ABSTRACT:
A rechargeable battery of alkali metal, organic electrolyte tape has a low surface area particulate carbonaceous electrode intercalable with the alkali metal and experiences little capacity loss upon intercalation of the carbonaceous electrode with the alkali metal. The carbonaceous electrode may include a multi-phase composition including both highly graphitized and less graphitized phases or may include a single phase, highly graphitized composition which has been subjected to interlation of lithium at above about 50.degree. C. Incorporation of an electrically conductive filamentary material such as carbon black intimately interspersed with the carbonaceous composition minimizing capacity loss upon repeated cycling.
