Abstract
Electrochemical cells containing lithium and a solid polymer electrolyte in the form of thin films are produced by making multilayer assemblies from double-layer solid polymer electrolyte/composite positive electrode sub-assemblies which are subsequently associated with the other constituent layers of the cell so that the multilayer assembly so obtained comprises a layer of a metal of low ductility. Cells may be made from multilayer assemblies by stacking, rolling or bending techniques.
