Abstract

Materials and methods for a coated active electrode material for use in a lithium-ion battery is provided. In one example, a coating for an active electrode material or active electrode material precursor of an electrode of a battery cell may include lithium, boron, and oxygen. In particular, the coating may include lithium tetraborate (LBO), and the coating may be coated on a lithium insertion electrode active material such as lithium nickel manganese cobalt oxide (LiNiMnCoOor NMC).
