Abstract
Abstract Disclosed herein is an electrochemical battery having electrodes immersed in an organic solvent electrolyte solution so that the electromotive force is generated by doping to and/or undoping from said electrodes. One electrode is made of metal which is electrochemically equilibrated with cations in the electrolyte, and the other electrode is made of carbon molded product having a specific surface area of 100 to 2,500 m2/g. The electrodes according to this invention are capable of accepting a large quantity of doping, light in weight and easy to handle.
