Abstract

A composite electrode for a rechargeable lithium battery is described. The composite electrode has a metallic current collector in contact with an electrically conducting organic polymer laminate made of a blended and annealed polymeric mixture containing fine carbon particles, and coated with an electrode-active substance bearing layer. The conducting polymer is capable of reversible resistivity changes of several orders of magnitude in only a portion of the laminate, thereby reducing locally excessive current flow and over-heating in the rechargeable lithium battery.
