摘要： PURPOSE:To increase the coefficiency of utilization of a positive electrode and improve the discharge characteristics in high current densities by comprising the positive electrode with a cylindrical porous carbon substance and a liquid-penetrating metal collector and providing the metal collector in contact with a separator at a negative electrode side. CONSTITUTION:A positive electrode 3' is comprised with a cylindrical porous carbon substance 6, metal collector 7' made of the cylindrical wire gauge provided in contact with a separator 4 at a negative electrode 2 side, and cylindrical separator 14. Consequently, even when the discharge product of a positive electrode active material that is the component material of an electrolyte is accumulated on a porous carbon substance during use, an increase of the impedance of the positive electrode 3' can be prevented due to the high resistance of the porous carbon substance 6. As a result, if the positive electrode active material of the electrolyte is fully contained in an outer can 1, the positive electrode 3' can effectively be used and the discharge characteristics in high current densities can be improved.
