This invention provides a method for producing a quasi-solid state charge storage device capable of being repeatedly charged and discharged, having one or more electrochemical cells with a structure capable of being stacked or combined to form primary or secondary battery devices, each cell composed entirely of an ionically conducting gel polymer electrolyte layer separating opposing surfaces of electronically conducting conjugated polymeric anode and cathode electrodes supported on lightweight porous substrates; a method of forming conjugated polymers into large area composite electrode structures with practical levels of charge storage capacity; and a quasi-solid state charge storage device produced by the above methods.
