Abstract

Li[Ni0.6Co0.2Mn0.2]O2(NCM622) is one of the best commercialized cathodes in the battery field. However, poor cyclability at relatively high temperature hinders its multiple usages. Here, operando tests were performed to investigate the phase transitions and electron/ion transfer process of layered NCM622 at 25 and 55 °C. The identified spinel structure resulting in the poor cyclability at 55 °C guides the commercialization of batteries at high temperature.
