In order to meaningfully compare active battery materials with different properties, it is important to consider both the intrinsic electrochemical properties and the differences in the porous electrode structures at the same practically relevant area capacities. In this study, graphite and microsilicon anodes with a practical area capacity of 2.8 mAh cm-2 for lithium-ion batteries are compared… [read more]

The study investigates the stability limits of layered transition metal oxides (LiMO2) with higher nickel content as cathode active materials (CAMs). The improved performance is attributed to the lower potential of nickel-rich CAMs, which prevents detrimental electrolyte oxidation. The research finds that the stability of CAMs is determined by their composition and structural stability during… [read more]
