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 using an active material composition with a liquid content such that active material is filtered out by the porous envelope, and a bed of active material is built up in the envelope, the bed building up from the end remote from that at which the composition is introduced back to the end at which the composition is introduced, liquid issuing through the walls of the envelope throughout the period that the bed is being built up.
A variety of suitable active material compositions are described together with apparatus suitable for carrying out the method.
