摘要：

A material and method for a surface-treated electrode active material for use in a lithium ion battery is provided. The surface-treated electrode active material includes an ionically conductive layer comprising a multivalent metal present as a direct conformal layer on at least a portion of the outer surface of the electrode active material. The surface-treated electrode active material improves the capacity retention and cycle life as well as reduces undesirable reactions at the surface of the electrode active material.
