Abstract
There is disclosed a method for preparing enveloped plates for batteries by introducing an active material composition containing liquids into the porous envelope of the plate, when the envelope is assembled on the current conducting element of the plate, the active material composition being 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 being one which 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.
