ABSTRACT:
A polyelectrolytic battery wherein a porous film having a polyelectrolyte impregnated into its cavities is interposed between a positive electrode and a negative electrode, the porous film having a porosity of not less than 80% and the polyelectrolyte impregnated therein at a ratio of 20 to 90% by volume of the cavities thereof. Another polyelectrolytic battery includes a positive electrode, a negative electrode including a carbon material, and a polyelectrolytic film interposed between the positive and negative electrodes, the positive and negative electrodes each containing a polyelectrolyte composed of a high polymer having a polystyrene main chain and a side chain of polyethlene oxide and a lithium salt.
