Abstract
An all solid state battery power source which operates efficiently at room temperature. The battery includes (1) a solid state protonic conductor electrolyte, (2) an anode active material based on an aromatic organic compound capable of producing protons and electrons in an anodic reaction during battery discharge, and (3) a solid cathode capable of reacting with protons. Anode and cathode active materials can be chosen so that the battery has the feature that the electrochemical reactions at the anode and cathode are at least partially reversible. It is suitable for electronic consumer products, biomedical applications, electric vehicle applications, and the like. The battery can be fabricated in any desired shape without any special production precautions.
