Foulkes, S C

There is disclosed a method for preparing enveloped plates for batteries. An active material composition containing liquids is introduced into the porous envelope of the plate when the envelope is assembled on the current-conducting element of the plate. The active material composition is an alkaline active material composition with a liquid content such that active material is filtered out by the porous envelope, while liquids pass out through the walls of the porous envelope. There is also disclosed a novel alkaline electric storage battery electrode comprising a porous envelope enclosing within it particulate active material which is electrochemically active under alkaline conditions. The porous envelope is capable of filtering out a bed of active material from an aqueous slurry of the active material containing 0.5 parts of the active material per part of water. 15 figures, 8 tables.
