Abstract
A method is described for placing electrochemically-active material in the pores of sintered nickel plaques. The plaque is first immersed in aqueous nickel nitrate; then the nickel nitrate in the pores is decomposed at high temperatures to an intermediate which converts rapidly to nickel hydroxide in caustic solutions. The effects of temperature and time of immersion and of thermal decomposition, and of the surrounding atmosphere, have been studied. Results on electrical behavior of the plates are presented, and a preliminary discussion of the mechanism of the impregnation process is offered.
