During solid‐state calcination, with increasing temperature, materials undergo complex phase transitions with heterogeneous solid‐state reactions and mass transport. Precise control of the calcination chemistry is therefore crucial for synthesizing state‐of‐the‐art Ni‐rich layered oxides (LiNi1‐x‐yCoxMnyO2, NRNCM) as cathode materials for lithium‐ion batteries. Although the battery performance depends...
Cathode Calcination
In article number 2207076, Sugeun Jo, Keeyoung Jung, Jongwoo Lim, and co‐workers show how solid‐state reaction heterogeneity affects the high‐temperature calcination of Li‐ion battery particles. Various parallel and serial combinations of the thermal (an)aerobic decomposition and Li2–O insertion/diffusion are chemically imaged during the calcination reaction. The cover image features...
