Abstract

Li-Ion Batteries In article number 2206576, Pilgun Oh and co-workers report a novel air- and moisture robust surface modification for LiNi0.8Co0.1Mn0.1O2 via the sol-gel coating method that selectively coats the internal surface area of the secondary particles. The LiCoO2-coated LiNi0.8Co0.1Mn0.1O2 exhibits high-capacity retention after exposure to all tested environments, due to the internal surface coating that prevents the penetration of harmful compounds into the polycrystalline structure.
