ELECTROCHEMICAL CELL WITH CARBONACEOUS MATERIAL AND MOLYBDENUM CARBIDE AS ANODE

摘要

A rechargeable lithium ion electrochemical cell (101) and/or battery configured to provide improved reversible energy storage capacity is disclosed. The electrochemical cell (101) and/or battery comprising a body o f aprotic, non-aqueous electrolyte, first and second electrodes (102,104) in effective electrochemical contact with the electrolyte, the first electrode (102) comprising a cathode formed by active materials such as a lithiated intercalation compound and the second electrode (104) comprising an anode formed by a carbonaceous material combined with molybdenum carbide. An electrochemical lithium ion cell (101) and/or battery according to the invention is designed to provide improved reversible energy storage capacity characteristics as compared with similar lithium-ion cells having carbon anodes that are not combined with molybdenum carbide.
