Abstract

There is provided a series of novel particulate stabilized lithiated compounds which can be utilized as cathodic materials in lithium ion battery cells. Each particle of the material defines an inner lithiated metal oxide core which acts as an intercalation cathode. A lithium ion conductor coating surrounds the core to stabilize the latter and to improve the electrochemical properties of the material.
