Abstract
High-Ni layered oxides are promising next-generation cathodes for lithium-ion batteries owing to their high capacity and lower cost. However, as the Ni content increases over 70 %, they have a high dynamic affinity towards moisture and CO2 in ambient air, primarily reacting to form LiOH, Li2 CO3 , and LiHCO3 on the surface, which is commonly termed residual lithium. Air exposure occurs after synthesis as it is common practice to handle and store...
