Abstract
Ozonated manganese dioxide is prepared by an ozonation process and utilized as a cathode active material. An ozone containing gas stream contacts manganese dioxide and produces ozonated manganese dioxide with high efficiency. After preparation, ozonated manganese dioxide is stored for a limited time at a low temperature and incorporated into a cathode active material for alkaline batteries.
