Abstract

Cobalt-free cathode materials like LNMO (LiNi0.5Mn1.5O4) are promising candidates on the way to more sustainable and affordable batteries. However, up to now the cycle life of LNMO full cells is limited. To tackle this challenge, LNMO-based prototype pouch cells are developed and built in the Horizon 2020 project Hydra. In this talk, we will present the results from the comprehensive analysis of their performance and cycling behavior. The influence of upper cut-off voltage, charge and discharge current rate as well as temperature on the degradation are thoroughly investigated by electrochemical methods such as differential voltage analysis and impedance spectroscopy. We thereby analyze the main degradation modes as a function of the cycling conditions and derive solutions on how to increase the cycle life.
