Method for fabricating electrodes for use in lead storage batteries

摘要

A method for fabricating an electrode for use in lead storage batteries in which an aqueous emulsion of a silicone capable of forming an elastic, porous matrix on breaking of the emulsion, is contacted with a finely divided active electrode material at the stage of preparing an electrode paste, or after formation as an electrode. The contacted material is dried, so that the elastic, porous silicone matrix formed in association with and in intimate contact with the finely divided active electrode material. An aqueous dispersion of fluorocarbon resin can be further added to the paste, or an electrode having a fibrous network of fluorocarbon resin can be applied with the silicone emulsion. Fine particles obtained from the silicone emulsion can also be applied to a finely divided active electrode material.
