Here, we characterized electrodes consisting of activated carbon with polyacrylic acid binder in four different concentrations of sulfuric acid, using cyclic voltammetry and electrochemical impedance spectroscopy. Both datasets were evaluated with simple equivalent circuits and comparatively analyzed. Conductivity of the electrolyte was independently measured. Cyclic voltammograms (CV) show larger resistance and capacitance at low scan rates. Resistances obtained from EIS are in good agreement with those obtained by cyclic voltammograms particularly at high scan rates. The comparison against specific electrolyte resistance can reveal whether resistances within the solid electrode architecture or resistances within the electrolyte, partially confined by pores, are the dominant cause of increased resistance at low scan rate. Comparison between CV and EIS points to the main electrode capacitance being described by a constant phase element (CPE) used to fit the low-frequency region of EIS.","lang":"eng"}],"status":"public"},{"title":"Assessment of the Physicochemical Meaning of the Ohmic Series Resistance Observed for High Frequencies in Electrochemical Impedance Spectra","doi":"10.1109/iwis61214.2023.10302764","date_updated":"2026-01-19T15:40:41Z","publisher":"IEEE","date_created":"2025-12-03T15:58:28Z","author":[{"first_name":"Sebastian","last_name":"Reinke","full_name":"Reinke, Sebastian","id":"117727"},{"first_name":"Vera","full_name":"Khamitsevich, Vera","last_name":"Khamitsevich"},{"first_name":"Oliver","full_name":"Röth, Oliver","id":"117786","last_name":"Röth"},{"last_name":"Linnemann","orcid":"0000-0001-6883-5424","id":"116779","full_name":"Linnemann, Julia","first_name":"Julia"}],"year":"2023","citation":{"ama":"Reinke S, Khamitsevich V, Röth O, Linnemann J.

Although these structural features are crucial for their performance, the mechanisms behind such transitions are not well understood. Herein, we describe the mechanism of transformation from layered 2D δ-MnO2 nanosheets to the scarcely reported γ-MnO2 nanocone morphology. 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. We propose and demonstrate a Mn2+-mediated oxidative mechanism of coupled morphology/phase transformation subjected to the equilibrium of Fe and Mn ions during galvanic exchange reaction. These findings contribute to the understanding of the growth and morphology/phase transformations of manganese oxide nanostructures, providing insights for the rational design of nanomaterials."}],"publication":"Journal of Materials Chemistry A","title":"Mechanism of coupled phase/morphology transformation of 2D manganese oxides through Fe galvanic exchange reaction","date_created":"2025-12-03T16:02:15Z","publisher":"Royal Society of Chemistry (RSC)","year":"2022","issue":"45","quality_controlled":"1"},{"title":"Electrodeposited films to MOF-derived electrochemical energy storage electrodes: a concept of simplified additive-free electrode processing for self-standing, ready-to-use materials","date_created":"2025-12-03T15:43:52Z","publisher":"Royal Society of Chemistry (RSC)","year":"2017","issue":"35","quality_controlled":"1","language":[{"iso":"eng"}],"keyword":["electrodeposition","metal-organic framework","MOF","supercapacitors"],"abstract":[{"text":"The thermolysis of electrodeposited metal–organic framework (MOF) films represents a novel approach to build supercapacitor electrodes of already electrically contacted MOF-derived high-performance metal oxide/carbon materials which are also highly interesting for other applications. 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. The pseudocapacitive properties of conventionally coated films of this powder material are limited.","lang":"eng"}],"publication":"Journal of Materials Chemistry A","doi":"10.1039/c7ta01874f","main_file_link":[{"open_access":"1"}],"volume":5,"author":[{"id":"116779","full_name":"Linnemann, Julia","last_name":"Linnemann","orcid":"0000-0001-6883-5424","first_name":"Julia"},{"first_name":"Laura","full_name":"Taudien, Laura","last_name":"Taudien"},{"last_name":"Klose","full_name":"Klose, Markus","first_name":"Markus"},{"first_name":"Lars","last_name":"Giebeler","full_name":"Giebeler, Lars"}],"date_updated":"2025-12-03T16:34:29Z","oa":"1","page":"18420-18428","intvolume":"         5","citation":{"ieee":"J.

In this study, the capacitive properties of electrodeposited cobalt hydroxide/oxide were investigated in 1 M Na2SO4 solution with pH 5.5 by means of cyclic voltammetry, galvanostatic charging/discharging experiments and electrochemical impedance spectroscopy. The capacitance of the cobalt hydroxide/oxide was demonstrated to have high values of 141 F g−1 at scan rate 8 mV s−1 in this 1 M Na2SO4 solution. The anodic potential range is extended by 0.8–1.3 V vs. Ag/AgCl. A good cyclic stability and reversibility were observed.","lang":"eng"}],"publication":"Electrochimica Acta"}]
