Abstract
The disclosure of this application is directed to silver catalyzed manganese dioxide which is useful as a hydrogen gas absorber. The silver catalyzed manganese dioxide of this invention can be formed into a shaped article of desired configuration, inserted into an electrochemical cell such as a battery, which is subsequently sealed, to absorb hydrogen gas evolved within the cell. Absorption of hydrogen gas by the silver catalyzed manganese dioxide prevents excessive build-up of gas pressure within the sealed cell thus minimizing the possibility of rupture and complete failure of the cell.
