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}}, 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}}, issn = {{2050-7488}}, journal = {{Journal of Materials Chemistry A}}, keywords = {{Xray}}, number = {{12}}, publisher = {{Royal Society of Chemistry (RSC)}}, title = {{{Insights into the First Multi-Transition-Metal Containing Ruddlesden Popper-Type Cathode for all-solid-state Fluoride Ion Batteries}}}, doi = {{10.1039/d4ta00704b}}, year = {{2024}}, } @article{34099, abstract = {{Using a unique combination of advanced characterization techniques, we identify specific degradation mechanisms and quantify degradative species formed during fast charge cycling of lithium-ion battery pouch cells.}}, author = {{McShane, Eric J. and Paul, Partha P. and Tanim, Tanvir R. and Cao, Chuntian and Steinrück, Hans-Georg and Thampy, Vivek and Trask, Stephen E. and Dunlop, Alison R. and Jansen, Andrew N. and Dufek, Eric J. and Toney, Michael F. and Weker, Johanna Nelson and McCloskey, Bryan D.}}, issn = {{2050-7488}}, journal = {{Journal of Materials Chemistry A}}, keywords = {{General Materials Science, Renewable Energy, Sustainability and the Environment, General Chemistry}}, number = {{44}}, pages = {{23927--23939}}, publisher = {{Royal Society of Chemistry (RSC)}}, title = {{{Multimodal quantification of degradation pathways during extreme fast charging of lithium-ion batteries}}}, doi = {{10.1039/d2ta05887a}}, volume = {{10}}, year = {{2022}}, } @article{40556, abstract = {{ In situ TEM heating experiments combined with extensive chemical, structural and sorption analysis reveal the nanoscale mechanism of porosity formation in carbonaceous materials obtained directly from molecular precursors.}}, author = {{Piankova, Diana and Kossmann, Janina and Zschiesche, Hannes and Antonietti, Markus and Lopez Salas, Nieves and Tarakina, Nadezda V.}}, issn = {{2050-7488}}, journal = {{Journal of Materials Chemistry A}}, keywords = {{General Materials Science, Renewable Energy, Sustainability and the Environment, General Chemistry}}, number = {{47}}, pages = {{25220--25229}}, publisher = {{Royal Society of Chemistry (RSC)}}, title = {{{Following carbon condensation by in situ TEM: towards a rational understanding of the processes in the synthesis of nitrogen-doped carbonaceous materials}}}, doi = {{10.1039/d2ta05247d}}, volume = {{10}}, year = {{2022}}, } @article{40557, abstract = {{Laser patterning of different precursor mixtures allows modulating the selectivity of iron oxide supported on N-doped carbons for ORR electrocatalysis.}}, author = {{Wang, Huize and Jerigova, Maria and Hou, Jing and Tarakina, Nadezda V. and Delacroix, Simon and Lopez Salas, Nieves and Strauss, Volker}}, issn = {{2050-7488}}, journal = {{Journal of Materials Chemistry A}}, keywords = {{General Materials Science, Renewable Energy, Sustainability and the Environment, General Chemistry}}, number = {{45}}, pages = {{24156--24166}}, publisher = {{Royal Society of Chemistry (RSC)}}, title = {{{Modulating between 2e− and 4e− pathways in the oxygen reduction reaction with laser-synthesized iron oxide-grafted nitrogen-doped carbon}}}, doi = {{10.1039/d2ta05838c}}, volume = {{10}}, year = {{2022}}, } @article{62813, abstract = {{Nanostructured manganese oxides have a rich variety of morphologies and crystal phases which can undergo transformations during synthesis and application.

Despite the common purpose of introducing Fe dopants to enhance the conductivity of layered manganese oxides, the Fe galvanic exchange reaction was found responsible for such coupled phase/morphology transition. Electrochemical characterization confirmed a distinct electrochemical behaviour of the nanocones, emphasizing the need to unravel the mechanism of 2D MnO2 transformation. Such mechanistic insights were gained by systematic and rigorous electron microscopy studies. The effect of the local chemical composition was determined by energy dispersive X-ray spectroscopy while electron energy loss spectroscopy unravelled the key influence of the oxidation state of Mn ions within nanosheets and nanocones.

Li–S batteries hold great promise as the upcoming post-lithium-ion batteries owing to their notably high theoretical specific energy density of 2600 W h kg−1, nearly five-fold larger than that of current lithium-ion batteries. However, one of their major technical problems is found in the shuttling of soluble polysulfides between the electrodes, resulting in rapid capacity fading and poor cycling stability. This review spotlights the foremost findings and the recent progress in enhancing the electrochemical performance of Li–S batteries by using nanoscaled metal compounds and metals. Based on an overview of reported functional metal-based materials and their specific employment in certain parts of Li–S batteries, the underlying mechanisms of enhanced adsorption and improved reaction kinetics are critically discussed involving both experimental and computational research findings. Thus, material design principles and possible interdisciplinary research approaches providing the chance to jointly advance with related fields such as electrocatalysis are identified. Particularly, we elucidate additives, sulfur hosts, current collectors and functional interlayers/hybrid separators containing metal oxides, hydroxides and sulfides as well as metal–organic frameworks, bare metal and further metal nitrides, metal carbides and MXenes. Throughout this review article, we emphasize the close relationship between the intrinsic properties of metal-based nanostructured materials, the (electro)chemical interaction with lithium (poly)sulfides and the subsequent effect on the battery performance.

MOFs are widely utilised as precursors to synthesise functional materials by thermal decomposition (pyrolysis, carbonisation). Using electrochemically coated MOF precursor films instead of powder greatly simplifies the processing of such materials and potentially enhances the resulting active materials' performance. In the case of electrochemical energy storage electrodes, the coated substrate later functions as current collector which is well-attached to the active material without the need for any additives. This close connection decreases electron transfer resistances and saves multiple steps of powder formulation and coating. Films of a metal–organic framework based on 1,3,5-benzene-tricarboxylate (BTC) and cobalt(II) cations were electrochemically coated on cobalt foils which act as the Co2+ cation source. Manganese films were electrodeposited and subsequently partly redissolved in a linker-containing electrolyte to achieve Mn/Mn–BTC bilayered films on stainless steel. This procedure extends the method for any kind of current collector material. The films were thermolysed to gain nanostructured metal oxide spinel (Me3O4)/carbon hybrid electrodes. Investigations of the electrochemical properties in regard to supercapacitor applications show that Co3O4/C films exhibit pseudocapacitance and that Mn3O4/C films are suitable for redox electrodes with high-rate capability operating in a wide potential range in aqueous electrolytes. Co–BTC powder was also thermally treated yielding cobalt particles embedded in a graphitic carbon matrix.
