Abstract
A secondary lithium electrochemical charge storage device, such as a battery (10) is taught. The battery (10) includes a first composite electrode (20), and electrolyte layer (40), and a second composite electrode (30). The composite electrodes include at least an active material, and a polymer or polymer blend for lending ionic conductivity and mechanical strength. The electrolyte may also include a polymer as well as an electrolyte active material. The polymer from which the composite electrode is fabricated may be the same as or different than the polymer from which the electrolyte layer is fabricated.
