CONDUCTIVE DILUENT FOR PRESSED NICKEL ELECTRODES

摘要

The conductive diluent is a combination of powdered carbon (preferably graphite) and nickel flakes. It is admixed with the active electrode material and a binder in the pressed nickel electrode so that the diluent is substantially homogeneously mixed with the active electrode material and is mixed in proportions (by weight) sufficient to provide between about 4% to about 10% of nickel flake and between about 5% to about 10% of powdered carbon within a preferred total conductive diluent range of 10-15%, with the remainder of the nickel electrode admixture essentially comprising active electrode material with a small amount of binder.
