RECHARGEABLE ELECTROCHEMICAL CELL HAVING A SOLID ELECTROLYTE

摘要

A rechargeable electrochemical cell comprising a cathode, an anode based on a carbon-containing material capable of intercalating lithium ions, and an electrolyte constituted by a cross-linked polymer incorporating a lithium salt and a dipolar aprotic solvent. At least the surface of the carbon-containing material is less crystallized than graphite so as to be impermeable to said solvent, while allowing the lithium to diffuse.
