The role of antimony on the lead-acid battery negative in terms of its effect on charge efficiency, its effect on gassing overpotential, its interactive influence with lignin expander in controlling the charge efficiency, and its retentive behavior or purging characteristics as SbH/sub 3/ in the overcharge gas stream was investigated. Linear potential sweep (LPS) cycling of Plante-type lead electrodes were used to determine the effect of antimony on gassing overpotential and to monitor its concentration either in the active material or the exit gas stream. Results showed a significant contribution of antimony in decreasing charge efficiency and an overwhelming role of lignin expander in suppressing the effect of antimony on charge efficiency. The critical lead-electrode potential for purging antimony from the electrode is close to -1275 mV (vs. Hg/Hg/sub 2/SO/sub 4/).
