Sealed lead-acid electric vehicle battery: Research and development: Final report

OSTI ID:5584061

A multi-year cell development effort leading to a sealed lead-acid battery for fleet electric vans has been completed. The cell design features a calcium-tin alloy using thin grids in a deep cycle application. A horizontal element positioning is used in conjunction with positive axial pressure which is applied to the element stack in order to extend cycle life. Cell operation at 45/sup 0/C provides a means to augment the specific power and specific energy characteristics. Four engineering models, incorporating several design and operational variables, were constructed and tested at JPL. At the time the program was discontinued, 400 cycles had been achieved; this coincided with near-term program objectives. 4 refs., 34 figs., 14 tab.
