Synthesis, Structure, Solid State NMR Spectroscopy, and Electronic Structures of the Phosphidotrielates Li3AlP2 and Li3GaP2 / T. M. F. Restle, J. V. Dums, G. Raudaschl-Sieber, T. F. Fässler / Chemistry - A European Journal 10.1002 (2020), DOI In this publication Li3AlP2 and Li3GaP2 are introduced as two new representatives of lithium phosphidotrielates and… [read more]

Scientists of the Chair of Technical Electrochemistry study the chemical and electrochemical processes leading to the degradation of the standard Li-ion battery. [read more]

Scientists study the growth of solid electrolyte interphases (SEI) on graphite anodes in the graphite-NMC-cells and characterize the accumulation of Li on the graphite particles. Furthermore the impact of lamination, formation and cycling of the cell on this SEI accumulation was quantified. [read more]

Modelling of the Calendering Process of NMC-622 Cathodes in Battery Production Analyzing Machine/ Material–Process–Structure Correlations David Schreiner,* Maximilian Oguntke, Till Günther, and Gunther Reinhart / Energy Technology 7.11 (2019): 1900840, DOI [read more]

In the recent publication "Li-ion half-cells studied operando during cycling by small-angle neutron scattering" a Li-ion half-cell with a graphite electrode is cycled against a metallic lithium counter-electrode using small-angle neutron scattering. [read more]

The recently published paper "Analysis and modeling of cycle aging of a commercial LiFePO4/graphite cell" by Dr. Maik Naumann and co-authors deals with the cyclic aging of commercial LFP graphite cells and its modeling.   Based on a large-scale cycling experiment, the most important influencing parameters for aging were identified and transferred into a semi-empirical… [read more]
