ABSTRACT:
A method for manufacturing flat or planar batteries wherein a carbon-impregnated polymeric carrier web which is selectively zonally prelaminated with continuous strips of metal ultimately serving current collector purposes is machined to form discrete current collctor subassemblies as an initial step of production. Through the use of select laser cutting, geometries of individual battery elements are maintained. Chemical milling techniques may be utilized for the noted metal removal.
