Lithium carbide composition, cathode, battery and process

摘要

The gist of the instant invention is the use of lithium carbide in the cathode of a rechargeable lithium ion battery. Lithium carbide is used to electrochemically release electrons and lithium ions from the cathode. A preferred cathode of the instant invention is graphite intercalated with a mixture of lithium carbide and a lithium salt such as lithium tetrafluoroborate.
