Neben der Füllstoffart ist dabei der Füllstoffvolumenanteil relevant. Der maximal verarbeitbare Füllstoffanteil ist hier gegenüber vergleichbaren Spritzgussmaterialien reduziert. An der Kunststofftechnik Paderborn (KTP) wurde untersucht, welchen Einfluss spezifische Füllstoffe auf die Materialeigenschaften haben. Die additive Fertigung (AM) gewinnt durch stetig steigende Anforderungen an die Bauteilkomplexität und Fertigungsflexibilität nicht nur im Prototypenbau an Bedeutung [1]. Eines der am weitesten verbreiteten additiven Fertigungsverfahren ist dabei das Fused Filament Fabrication (FFF) Verfahren [2]. Bei diesem Verfahren wird ein Kunststofffilament in eine temperierte Düse gefördert, dort aufgeschmolzen und in einer charakteristischen, näherungsweise elliptischen Stranggeometrie ausgetragen. Durch die Verfahrbewegung der Plastifiziereinheit und der Bauplattform können dreidimensionale Strukturen gefertigt werden [3]. Das FFF-Verfahren zeichnet sich unter anderem durch die Verarbeitung einer großen Bandbreite an thermoplastischen Kunststoffen aus [4]. Dies ermöglicht eine anwendungsspezifische Materialauswahl. In diesem Zusammenhang stellt auch die Modifizierung mit Füllstoffen eine Möglichkeit dar, die Materialeigenschaften gezielt einzustellen. Die Füllstoffe können dabei nach dem jeweiligen Aspektverhältnis in Kugeln, Plättchen oder Fasern unterteilt werden [5]. Die Steigerung der Wärmeleitfähigkeit von im FFF-Verfahren hergestellten Strukturen ist aktuell Stand der Forschung, gewinnt jedoch vor dem Hintergrund der aktuellen Herausforderungen, z. B. in der Elektrotechnik, an Bedeutung [6]. Die Kunststofftechnik Paderborn (KTP) befasst sich am Direct Manufacturing Research Center (DMRC) – Academic derzeit mit der Entwicklung und Verarbeitung wärmeleitfähiger Kunststoffe für das FFF-Verfahren. Der Fokus liegt dabei auf den material- und prozessseitigen Einflüssen auf die Materialeigenschaften. Für die Erzielung hoher Wärmeleitfähigkeiten sind dabei die Wahl der Füllstoffart und des Füllstoffvolumenanteils hervorzuheben. Kenntnisse über die Auswirkungen der Füllstoffzugabe und dem Zusammenspiel zwischen den mechanischen Eigenschaften und der Wärmeleitfähigkeit sind für die anwendungsgerechte Bauteilauslegung essenziell. Das Vorgehen Zur Analyse der Wärmeleitfähigkeit wurde eine am DMRC – Academic entwickelte Methode verwendet. Diese basiert auf der Fertigung von zylindrischen Probekörpern, welche im FFF-Verfahren entlang der Längsachse parallel zu den drei Koordinatenrichtungen X, Y und Z orientiert gefertigt werden. Im Anschluss werden die Probekörper spanend auf das für die Messung erforderliche Maß nachbearbeitet. Dadurch können fertigungsbedingte Einflüsse auf die Geometrie und Oberflächengüte reduziert und damit die Messgenauigkeit erhöht werden (Bild 2). Durch die Fertigung von drei unterschiedlichen Orientierungen kann weiterhin eine resultierende Anisotropie bewertet werden. Die auf einem Doppelschneckenextruder (Thermo Fisher Process11) hergestellten Filamente wurden nachfolgend mit einem Gewo HTP260 (Gewo Feinmechanik) verarbeitet. Die entsprechenden FFF-Prozessparameter sind in Tabelle 1 dargestellt. Dabei ist anzumerken, dass eine Bauraumtemperierung im Allgemeinen und der auf 120 °C beheizte Bauraum für die Verarbeitung der betrachteten Materialien im Speziellen zur prozesssicheren FFF-Fertigung unerlässlich sind. Die Analyse der Wärmeleitfähigkeit erfolgte schließlich mittels der Laser-Flash-Analyse (LFA) (Netzsch LFA 467 HyperFlash) entsprechend der DIN EN ISO 22007-4 [7]. Für die Bewertung der mechanischen Eigenschaften wurden Probekörper entsprechend der DIN EN ISO 527-2 Typ 1BA unter Verwendung einer Kolben-Spritzgussmaschine (Thermo Fisher Mini Jet Pro) gefertigt und mit einer Zugprüfmaschine (Zwick/Roell ProLine Z 010) geprüft, um den grundlegenden Füllstoffeinfluss bewerten zu können [8]. Für die Untersuchungen wurde ein Kunststoff-Compound basierend auf Polybutylenterephthalat (PBT) ohne (PBTx) und mit (PBTxa) Verarbeitungshilfe verwendet. Als Füllstoffe kamen zwei wärmeleitfähige plättchenförmige Füllstoffe (Bezeichnung: F1 und F2) zur Anwendung, welche einen mittleren Partikeldurchmesser (d50) für F1 von 5,0 µm und für F2 von 7,9 µm aufweisen. Ergebnisse der Zugversuche Die Auswertung der mechanischen Eigenschaften zeigt den Einfluss des Füllstoffvolumenanteils anhand des Elastizitätsmoduls und der Bruchdehnung auf (Bild 3). Die resultierende Festigkeit wird durch die geringe Verstärkungswirkung der Plättchen hingegen nur geringfügig beeinflusst und ist folglich nicht gesondert aufgeführt. Im Gegensatz dazu erhöht sich die Steifigkeit mit steigendem Füllstoffvolumenanteil, was auf den erhöhten E-Modul der Füllstoffe gegenüber der Kunststoffmatrix zurückzuführen ist. So kann durch die Füllstoffzugabe mit einem Volumenanteil in Höhe von 22 {%} der E-Modul für das Material PBTxa-F1 gegenüber der reinen Kunststoffmatrix um den Faktor 2,7 gesteigert werden. Hingegen nimmt die Bruchdehnung mit steigendem Füllstoffvolumenanteil ab. Diese mit dem Volumenanteil positiv korrelierende Versprödung stellt einen begrenzenden Faktor bei der Herstellung hochgefüllter Filamente dar. So neigen höher gefüllte Filamente eher zu einem Bruch bei der Herstellung und Verarbeitung. Dies resultiert in den vorliegenden maximalen Füllstoffvolumenanteilen, welche im Vergleich zu Spritzgussmaterialien deutlich reduziert sind. Eine weitere Erhöhung führt zu einer unzureichenden Prozessstabilität und damit zu einer unzureichenden Verarbeitungseignung für das FFF-Verfahren. Weiterhin zeigt sich, dass der Einfluss der verwendeten plättchenförmigen Füllstoffe für eine identische Kunststoffmatrix vergleichbar ist. Durch die Verwendung von Verarbeitungshilfen können die mechanischen Eigenschaften allerdings beeinflusst werden. Die Erhöhung des E-Moduls und der Bruchdehnung ist dabei auf die verbesserte Benetzung der Füllstoffpartikel und damit eine verbesserte Kunststoff-Füllstoff-Interaktion zurückzuführen. Bewertung der Wärmeleitfähigkeit Zur Darstellung der Ergebnisse der Wärmeleitfähigkeit wurden die Messergebnisse von je vier Probekörpern über die Prüftemperaturen zwischen 30 °C und 180 °C in 30 °C Inkrementen gemittelt (Bild 4). Die Ergebnisse zeigen eine positive Korrelation zwischen einem zunehmenden Füllstoffvolumenanteil und der Wärmeleitfähigkeit. Diese Steigerung ist wiederum abhängig von der jeweilig verwendeten Füllstoffart. Hierbei liefert das Material PBTx-F2-X eine vergleichbare Wärmeleitfähigkeit wie die Materialien PBTx-F1 und PBTxa-F1 in der jeweiligen Y-Orientierung. Die Unterschiede zwischen den beiden Materialien PBTx-F1 und PBTxa-F1 sind hingegen minimal und der Einfluss der Verarbeitungshilfe auf die Wärmeleitfähigkeit dementsprechend als vernachlässigbar anzusehen. Weiterhin ist eine anisotrope Wärmeleitfähigkeit für die mit Plättchen gefüllten Kunststoffe ersichtlich. Während die X-Orientierung (entlang der abgelegten Stränge) eine erhöhte Wärmeleitfähigkeit für alle Materialien liefert, ist diese für die Z-Orientierung (zwischen den Schichten) am geringsten. Gründe hierfür sind der Strangverbund sowie die Füllstofforientierung innerhalb der abgelegten Stränge. Dabei ist die aufgezeigte Anisotropie für den Füllstoff F2 im Vergleich zu F1 leicht reduziert und bestätigt den spezifischen Einfluss der Füllstoffart. Auf Basis der Ergebnisse können allgemein drei charakteristische Orientierungen zur Bewertung der Wärmeleitfähigkeit erfasst werden. Für die Bauteilauslegung ist der aufgezeigte Einfluss plättchenförmiger Füllstoffe auf die sich einstellende Anisotropie von im FFF-Verfahren gefertigten Strukturen zwingend zu beachten. Ausblick Die angeführten Untersuchungen zeigen, dass die Verwendung von plättchenförmigen Füllstoffen in Abhängigkeit von dem Füllstoffvolumenanteil zu einer Beeinflussung der Materialeigenschaften führt. Die dargelegten Ergebnisse stellen in diesem Kontext eine Grundlage zur Bewertung des Zusammenhangs zwischen den mechanischen Eigenschaften und der Wärmeleitfähigkeit dar. Insbesondere die Limitierung des Füllstoffvolumenanteils durch die erhöhte Versprödung ist hierbei anzuführen. Aktuelle Untersuchungen an der Kunststofftechnik Paderborn befassen sich mit der Betrachtung weiterer material- und prozessseitiger Einflussgrößen auf die Wärmeleitfähigkeit. Die generierten Daten sollen schließlich für die Entwicklung eines Modells zur Vorhersage der Wärmeleitfähigkeit von im FFF-Verfahren gefertigten Strukturen zusammengeführt werden."}],"citation":{"mla":"Moritzer, Elmar, et al. “Wie Der Füllstoffvolumenanteil Die Materialeigenschaften Beeinflusst.” <i>Plastverarbeiter</i>, vol. 2024, 2024.","bibtex":"@article{Moritzer_Elsner_Salm_2024, title={Wie der Füllstoffvolumenanteil die Materialeigenschaften beeinflusst}, volume={2024}, journal={Plastverarbeiter}, author={Moritzer, Elmar and Elsner, Christian Lennart and Salm, Maximilian Karl Franz}, year={2024} }","ama":"Moritzer E, Elsner CL, Salm MKF.

For this purpose, different screw elements are used for dispersive and distributive mixing on a co-rotating twin-screw extruder. Optimising the screw configuration requires precise knowledge of the screw elements’ mixing properties, which have not been thoroughly investigated. This study analyses the mixing behaviour of individual screw elements regarding dispersive and distributive mixing using 3D CFD flow simulations with subsequent particle tracking. For distributive mixing, the particle distribution behind the screw elements in the XY plane is analysed and the mixing index MQ, which relates the standard deviation and the mean value of the triangular areas between the particles, is calculated. For dispersive mixing, the maximum shear stress on the particle path and the integral of the shear stress over the residence time of each individual particle are determined. The results show that screw element geometry and rotation speed have a significant influence on dispersive and distributive mixing. In addition, better dispersive mixing is achievable with highly viscous materials. These findings enable the optimisation of the mixing zone of a co-rotating twin-screw extruder for the efficient mixing of mineral fillers."}],"language":[{"iso":"eng"}],"_id":"59135","doi":"10.3390/polym16212952","user_id":"59363","volume":16,"title":"Analysis of the Dispersive and Distributive Mixing Effect of Screw Elements on the Co-Rotating Twin-Screw Extruder with Particle Tracking","year":"2024","status":"public","author":[{"id":"56781","full_name":"Oldemeier, Jan Philipp","first_name":"Jan Philipp","last_name":"Oldemeier"},{"id":"20530","first_name":"Volker","last_name":"Schöppner","full_name":"Schöppner, Volker"}],"date_updated":"2025-03-27T12:56:35Z","intvolume":"        16"},{"status":"public","title":"The Potential of DEM Simulation for the Prediction of Torque Differences in the Melting Zone of Co-rotating Twin-Screw Extruders","year":"2024","author":[{"first_name":"Laura","last_name":"Austermeier","full_name":"Austermeier, Laura","id":"45326"},{"id":"20530","last_name":"Schöppner","first_name":"Volker","full_name":"Schöppner, Volker"}],"date_updated":"2025-03-27T13:16:31Z","_id":"59133","publisher":" DCS Computing GmbH, TU Graz Institut für Prozess- und Partikeltechnik","language":[{"iso":"eng"}],"user_id":"59363","doi":"10.3217/978-3-99161-020-5","publication":"Book of Abstracts of the 5th Aspherix(R) & CFDEM(R) Conference","citation":{"chicago":"Austermeier, Laura, and Volker Schöppner. “The Potential of DEM Simulation for the Prediction of Torque Differences in the Melting Zone of Co-Rotating Twin-Screw Extruders.” <i>Book of Abstracts of the 5th Aspherix(R) &#38; CFDEM(R) Conference</i>, 2024. <a href=\"https://doi.org/10.3217/978-3-99161-020-5\">https://doi.org/10.3217/978-3-99161-020-5</a>.","short":"L.

Chief among them, barium titanate (BaTiO3; BTO) sees widespread applications such as in electronics but equally is a ferroelectric model system for fundamental research, e.g., to study the interplay of such FE domains, the domain walls (DWs), and their macroscopic properties, owed to BTO’s multiple and experimentally accessible phase transitions. Here, we employ Second Harmonic Generation Microscopy (SHGM) to in situ investigate the cubic-to-tetragonal (at ∼126°C) and the tetragonal-to-orthorhombic (at ∼5°C) phase transition in single-crystalline BTO via three-dimensional (3D) DW mapping. We demonstrate that SHGM imaging provides the direct visualization of FE domain switching as well as the domain dynamics in 3D, shedding light on the interplay of the domain structure and phase transition. These results allow us to extract the different transition temperatures locally, to unveil the hysteresis behavior, and to determine the type of phase transition at play (first/second order) from the recorded SHGM data. The capabilities of SHGM in uncovering these crucial phenomena can easily be applied to other ferroelectrics to provide new possibilities for in situ engineering of advanced ferroic devices.","lang":"eng"}],"date_created":"2025-04-02T15:57:11Z","department":[{"_id":"15"},{"_id":"623"},{"_id":"288"}],"type":"journal_article"},{"oa":"1","citation":{"mla":"Ratzenberger, Julius, et al. “Toward the Reproducible Fabrication of Conductive Ferroelectric Domain Walls into Lithium Niobate Bulk Single Crystals.” <i>Journal of Applied Physics</i>, vol. 136, no. 10, AIP Publishing, 2024, p. 104302, doi:<a href=\"https://doi.org/10.1063/5.0219300\">10.1063/5.0219300</a>.","bibtex":"@article{Ratzenberger_Kiseleva_Koppitz_Beyreuther_Zahn_Gössel_Hegarty_Amber_Rüsing_Eng_2024, title={Toward the reproducible fabrication of conductive ferroelectric domain walls into lithium niobate bulk single crystals}, volume={136}, DOI={<a href=\"https://doi.org/10.1063/5.0219300\">10.1063/5.0219300</a>}, number={10}, journal={Journal of Applied Physics}, publisher={AIP Publishing}, author={Ratzenberger, Julius and Kiseleva, Iuliia and Koppitz, Boris and Beyreuther, Elke and Zahn, Manuel and Gössel, Joshua and Hegarty, Peter A. and Amber, Zeeshan H. and Rüsing, Michael and Eng, Lukas M.}, year={2024}, pages={104302} }","ama":"Ratzenberger J, Kiseleva I, Koppitz B, et al.

One key requirement hereto is their reproducible manufacturing by gaining preparative control over domain size and domain wall conductivity (DWC). To date, most works on DWC have focused on exploring the fundamental electrical properties of individual DWs within single-shot experiments, with an emphasis on quantifying the origins of DWC. Very few reports exist when it comes to comparing the DWC properties between two separate DWs, and literally nothing exists where issues of reproducibility in DWC devices have been addressed. To fill this gap while facing the challenge of finding guidelines for achieving predictable DWC performance, we report on a procedure that allows us to reproducibly prepare single hexagonal domains of a predefined diameter into uniaxial ferroelectric lithium niobate single crystals of 200 and 300 μm thickness, respectively. We show that the domain diameter can be controlled with an uncertainty of a few percent. As-grown DWs are then subjected to a standard procedure of current-limited high-voltage DWC enhancement, and they repetitively reach a DWC increase of six orders of magnitude. While all resulting DWs show significantly enhanced DWC values, their individual current–voltage (I–V) characteristics exhibit different shapes, which can be explained by variations in their 3D real structure reflecting local heterogeneities by defects, DW pinning, and surface-near DW inclination.","lang":"eng"}],"language":[{"iso":"eng"}],"main_file_link":[{"url":" https://doi.org/10.1063/5.0219300","open_access":"1"}],"doi":"10.1063/5.0219300","publication_identifier":{"issn":["0021-8979","1089-7550"]},"author":[{"full_name":"Ratzenberger, Julius","first_name":"Julius","last_name":"Ratzenberger"},{"full_name":"Kiseleva, Iuliia","last_name":"Kiseleva","first_name":"Iuliia"},{"last_name":"Koppitz","first_name":"Boris","full_name":"Koppitz, Boris"},{"last_name":"Beyreuther","first_name":"Elke","full_name":"Beyreuther, Elke"},{"full_name":"Zahn, Manuel","first_name":"Manuel","last_name":"Zahn"},{"last_name":"Gössel","first_name":"Joshua","full_name":"Gössel, Joshua"},{"full_name":"Hegarty, Peter A.","first_name":"Peter A.","last_name":"Hegarty"},{"first_name":"Zeeshan H.","last_name":"Amber","full_name":"Amber, Zeeshan H."},{"id":"22501","full_name":"Rüsing, Michael","first_name":"Michael","orcid":"0000-0003-4682-4577","last_name":"Rüsing"},{"last_name":"Eng","first_name":"Lukas M.","full_name":"Eng, Lukas M."}],"title":"Toward the reproducible fabrication of conductive ferroelectric domain walls into lithium niobate bulk single crystals","year":"2024","article_type":"original","intvolume":"       136","publication_status":"published","date_updated":"2025-04-02T16:14:31Z"},{"issue":"22","publication":"Journal of Applied Physics","abstract":[{"lang":"eng","text":"Piezoresponse force microscopy (PFM) is one of the most widespread methods for investigating and visualizing ferroelectric domain structures down to the nanometer length scale. PFM makes use of the direct coupling of the piezoelectric response to the crystal lattice, and hence, it is most often applied to spatially map the three-dimensional (3D) near-surface domain distribution of any polar or ferroic sample. Nonetheless, since most samples investigated by PFM are at least semiconducting or fully insulating, the electric ac field emerging from the conductive scanning force microscopy (SFM) tip penetrates the sample and, hence, may also couple to polar features that are deeply buried into the bulk of the sample under investigation. Thus, in the work presented here, we experimentally and theoretically explore the contrast and depth resolution capabilities of PFM, by analyzing the dependence of several key parameters. These key parameters include the depth of the buried feature, i.e., here a domain wall (DW), as well as PFM-relevant technical parameters such as the tip radius, the PFM drive voltage and frequency, and the signal-to-noise ratio. The theoretical predictions are experimentally verified using x-cut periodically poled lithium niobate single crystals that are specially prepared into wedge-shaped samples, in order to allow the buried feature, here the DW, to be “positioned” at any depth into the bulk. This inspection essentially contributes to the fundamental understanding in PFM contrast analysis and to the reconstruction of 3D domain structures down to a 1 μm-penetration depth into the sample."}],"date_created":"2024-07-01T21:00:43Z","department":[{"_id":"15"},{"_id":"169"},{"_id":"288"},{"_id":"623"}],"keyword":["Ferroelectrics","lithium niobate","piezoresponse force microscopy"],"type":"journal_article","publication_identifier":{"issn":["0021-8979","1089-7550"]},"author":[{"last_name":"Roeper","first_name":"Matthias","full_name":"Roeper, Matthias"},{"full_name":"Seddon, Samuel D.","first_name":"Samuel D.","last_name":"Seddon"},{"full_name":"Amber, Zeeshan H.","last_name":"Amber","first_name":"Zeeshan H."},{"id":"22501","first_name":"Michael","orcid":"0000-0003-4682-4577","last_name":"Rüsing","full_name":"Rüsing, Michael"},{"full_name":"Eng, Lukas M.","first_name":"Lukas M.","last_name":"Eng"}],"title":"Depth resolution in piezoresponse force microscopy","year":"2024","article_type":"original","intvolume":"       135","publication_status":"published","date_updated":"2025-04-03T12:35:34Z","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://doi.org/10.1063/5.0206784","open_access":"1"}],"doi":"10.1063/5.0206784","citation":{"ama":"Roeper M, Seddon SD, Amber ZH, Rüsing M, Eng LM.

Addressing the key challenges in this endeavor, algorithms are described to reliably construct structurally compatible partitions of two shapes with constraints regarding star-shapedness and to compute a parsimonious common refinement of two triangulations.</jats:p>"}],"language":[{"iso":"eng"}],"doi":"10.1145/3687950","year":"2024","title":"Bijective Volumetric Mapping via Star Decomposition","author":[{"id":"116615","last_name":"Hinderink","first_name":"Steffen","full_name":"Hinderink, Steffen"},{"last_name":"Brückler","first_name":"Hendrik","full_name":"Brückler, Hendrik","id":"115694"},{"full_name":"Campen, Marcel","last_name":"Campen","orcid":"0000-0003-2340-3462","first_name":"Marcel","id":"114904"}],"publication_identifier":{"issn":["0730-0301","1557-7368"]},"publication_status":"published","date_updated":"2025-07-14T12:33:54Z","intvolume":"        43"},{"_id":"52346","publisher":"Royal Society of Chemistry (RSC)","language":[{"iso":"eng"}],"user_id":"48467","doi":"10.1039/d4ta00704b","status":"public","title":"Insights into the First Multi-Transition-Metal Containing Ruddlesden Popper-Type Cathode for all-solid-state Fluoride Ion Batteries","year":"2024","author":[{"full_name":"Vanita, Vanita","last_name":"Vanita","first_name":"Vanita"},{"full_name":"Waidha, Aamir Iqbal","first_name":"Aamir Iqbal","last_name":"Waidha"},{"last_name":"Vasala","first_name":"Sami","full_name":"Vasala, Sami"},{"full_name":"Puphal, Pascal","first_name":"Pascal","last_name":"Puphal"},{"full_name":"Schoch, Roland","first_name":"Roland","orcid":"0000-0003-2061-7289","last_name":"Schoch","id":"48467"},{"first_name":"Pieter","last_name":"Glatzel","full_name":"Glatzel, Pieter"},{"orcid":"0000-0002-9294-6076","first_name":"Matthias","last_name":"Bauer","full_name":"Bauer, Matthias","id":"47241"},{"full_name":"Clemens, Oliver","first_name":"Oliver","last_name":"Clemens"}],"publication_identifier":{"issn":["2050-7488","2050-7496"]},"publication_status":"published","date_updated":"2025-08-15T12:50:31Z","date_created":"2024-03-07T10:01:09Z","keyword":["Xray"],"type":"journal_article","department":[{"_id":"306"}],"issue":"12","publication":"Journal of Materials Chemistry A","citation":{"bibtex":"@article{Vanita_Waidha_Vasala_Puphal_Schoch_Glatzel_Bauer_Clemens_2024, title={Insights into the First Multi-Transition-Metal Containing Ruddlesden Popper-Type Cathode for all-solid-state Fluoride Ion Batteries}, DOI={<a href=\"https://doi.org/10.1039/d4ta00704b\">10.1039/d4ta00704b</a>}, number={12}, journal={Journal of Materials Chemistry A}, publisher={Royal Society of Chemistry (RSC)}, author={Vanita, Vanita and Waidha, Aamir Iqbal and Vasala, Sami and Puphal, Pascal and Schoch, Roland and Glatzel, Pieter and Bauer, Matthias and Clemens, Oliver}, year={2024} }","ama":"Vanita V, Waidha AI, Vasala S, et al.

So far, multi-elemental compositions were not investigated, but could alternate electrochemical performance similar to what has been found for cathode materials for lithium-ion batteries. Within this study, we investigate RP type La2Ni0.75Co0.25O4.08 as an intercalation-based active cathode material for all-solid-state FIBs. We determine the structural changes of La2Ni0.75Co0.25O4.08 during fluoride intercalation / de-intercalation by ex-situ X-ray diffraction, which showed that F- insertion leads to transformation of the parent phase to three different phases. Changes in Ni and Co oxidation states and coordination environment were examined by X-ray absorption spectroscopy and magnetic measurements in order to understand the complex reaction behaviour of the phases in detail, showing that the two transition metals behave differently in the charging and discharging process. Under optimized operating conditions, a cycle life of 120 cycles at a critical cut-off capacity of 40 mAh g-1 against Pb/PbF2 was obtained, which is one of the highest observed for intercalation electrode materials in FIBs so far. The average Coulombic efficiencies ranged from 85% to 90%. Thus, La2Ni0.75Co0.25O4.08 could be a promising candidate for cycling-stable high-energy cathode materials for all-solid-state FIBs","lang":"eng"}]}]
