IODINE CELL

Document Type and Number:

WIPO Patent Application WO/1985/001155

Kind Code:

A1

Abstract:

An iodine cell which has a depolarizing mix for cell positive electrode obtained in such a manner that a composite formed by setting iodine by means of a polymer having an ability to form a complex adduct in cooperation with iodine is allowed to dipersedly contain a carbonaceous material, such as carbon black or graphite. The iodine cell preferably employs a cation exchanger film as a separator. The iodine cell features high output, low internal resistance, high charging/discharging life (a high number of cycles), and long life and advantageously permits charging even in a state wherein almost all the iodine has been desorbed from the positive electrode. It is possible to use the iodine cell for a primary battery, more preferably a secondary battery.
