Poly(vinyl alcohol) is considered as a potential material in thin-layer ’all solid‘ batteries. By adding an appropriate doping agent, intrinsic ionic conduction is observed leading to its use as a solid electrolyte in zinc/halogen and zinc/metal oxide batteries. The association of zinc metal powder and conjugated salt in poly(vinyl alcohol) leads to a composite anode which acts as a proton generator or protode when the system is a proton conductor.
