Unraveling the Intricacies of Residual Lithium in High-Ni Cathodes for Lithium-Ion Batteries

Youngjin Kim et al.

Summary: High-nickel layered oxide cathodes face problems with residual lithium causing slurry gelation and gas evolution. A study showed that Li2CO3 impurity in lithium raw materials increases residual lithium in high-Ni cathodes, while LiOH formed during analyte preparation exacerbates LiOH content in residual lithium. A dry cobalt hydroxide coating on high-Ni cathodes effectively reduces residual lithium content and forms a Co-rich layer that suppresses Li leaching in contact with water.
