However, LixCoO2 is prone to disproportionation reaction to produce CoO2, and the product can react with oxygen to generate Co3O4. When Co3O4 is in contact with the electrolyte solution, the reaction continues to release heat under high charge, thus leading to “thermal runaway phenomenon...
Transition metal nitride (TMN-) based materials have recently emerged as promising non-precious-metal-containing electrocatalysts for the oxygen reduction reaction (ORR) in alkaline media. However, the lack of fundamental understanding of the oxide surface has limited insights into structure–(re)activit...
