METHOD FOR REDUCING GAS PRESSURE IN AN ELECTROCHEMICAL CELL

摘要

22,748 METHOD FOR REDUCING GAS PRESSURE IN AN ELECTROCHEMICAL CELL A method for treating carbon-containing cathodes of a primary electrochemical cell for the purpose of reducing the gas pressure in the cell during open circuit and during discharge of the cell. The method of the invention includes purging the carbon-containing cathodes of the cell with sulfur dioxide or thionyl chloride gas to displace water and insoluble gases (oxygen and nitrogen, and argon or helium) entrapped within the carbon of the carbon-containing cathodes. The purge gas is soluble in an electrolytic solution including liquid thionyl chloride as is employed to activate the cell for use in discharge.
