An expander formulation for use in a battery paste incorporates an organic component or lignosulfonate characterized by improved resistance to high temperature degradation. Battery plates made from battery pastes which incorporate this expander formulation exhibit considerable improvements in the life of the batteries, especially at high battery operating temperatures. The organic component preferably is a purified, partially desulfonated, high molecular weight sodium lignosulfonate made from softwood. |
