A negative electrode ( ) for a non-aqueous electrochemical cell ( ) with an intermetallic host structure containing two or more elements selected from the metal elements and silicon, capable of accommodating lithium within its crystallographic host structure such that when the host structure is lithiated it transforms to a lithiated zinc-blende-type structure. Both active elements (alloying with lithium) and inactive elements (non-alloying with lithium) are disclosed. Electrochemical cells and batteries as well as methods of making the negative electrode are disclosed.

Anodes for rechargeable lithium batteries

Improved lithium vanadium oxide formulations are presented having a nominal formula of Li,V,M,O,. Herein preferred cation doped vanadium oxide materials, electrodes using such materials, and electrochemical cells including at least one electrode therein comprising such materials are provided.
