Arrhenius plots for Li-ion battery ageing as a function of temperature, C-rate, and ageing state – An experimental study
Kucinskis, Gints; Bozorgchenani, Maral; Feinauer, Max; Kasper, Michael; Wohlfahrt-Mehrens, Margret; Waldmann, Thomas (Elsevier, 2022)We present an extensive analysis of Li-ion battery ageing via Arrhenius plots. The V-shaped Arrhenius plots show minima at an optimum temperature corresponding to the longest cycle-life. The V-shape of the Arrhenius plots ... -
Experimental Confirmation of C-Rate Dependent Minima Shifts in Arrhenius Plots of Li-Ion Battery Aging
Bozorgchenani, Maral; Kucinskis, Gints; Wohlfahrt-Mehrens, Margret; Waldmann, Thomas (The Electrochemical Society, 2022)Li-ion batteries show a minimum of their aging rate at a certain temperature. This minimum in the corresponding Arrhenius plot expresses the longest cycle life at a certain C-rate. By characterizing aging of laboratory-made ...
