Abstract
A method of making a lead-acid storage battery including the step of depositing antimony on the surface of a substantially non-antimonial lead grid used for positive plates. The antimony film/deposit extends the cycle life of non-antimonial grids by maintaining paste-to-grid adhesion without (1) significantly degrading battery initial performance, (2) substantially decreasing the hydrogen overvoltage which leads to gassing, and (3) substantially increasing the battery's tendency toward self-discharge.
