<p>PCT No. PCT/JP84/00416 Sec. 371 Date Apr. 17, 1985 Sec. 102(e) Date Apr. 17, 1985 PCT Filed Aug. 30, 1984 PCT Pub. No. WO85/01155 PCT Pub. Date Mar. 14, 1985.This invention provides an iodine cell in which a composition obtained by including a carbon such as carbon black and graphite in dispersed form in a composition comprising iodine and a polymer having the ability to form a complex adduct with it, said polymer fixing iodine, is used as a positive electrode material and preferably a cation exchange membrane is used as a separator. The iodine cell is characterized by having a high output, a low internal resistance, a high charging-discharging life (a large cycle number) and a long service life and being able to be charged even when almost all of iodine has been liberated from the positive electrode. It can be used suitably as a primary cell, preferably as a secondary cell.</p> |
