Consumers require lead-acid batteries with a high level of reliability, low cost and improved life, and/or with less weight and good tolerance to high-temperature operation. To reduce the thickness (weight) of the grids, the alloy materials must exhibit higher mechanical properties and improved corrosion resistance. In this study, the performance of negative and positive grids is evaluated in battery...
The operating conditions of automotive and some industrial batteries are involving increasingly higher temperatures and heavier duty cycles. These place stress on the positive-grid materials which are presently not sufficiently resistant to corrosion and to creep. Conventional lead-calcium-tin-aluminium alloys can usually be optimized by a proper choice of calcium and tin contents for each specific...
