Abstract
A composite carbon/polymer electrode for a rechargeable electrochemical lithium cell comprises a powder of carbonaceous material and a coating polymer rendered ionically conductive by the addition of a lithium salt, and possibly carbon black or carbon fibers. The carbonaceous material has a proportion of volatile matter between 5 and 22 wt %, and is preferably a raw coke or a semi-coke.
