A new approach to the design of lead/acid batteries has been developed based upon the use of very thin, lead foil current collectors and a unique method for facilitating high current-carrying capacity to and from external sources. The basic cell construction and the performance characteristics for this valve-regulated lead/acid design are described. Spiral-wound cells with electrode/cast-on-strap (COS) configuration exhibit extremely high power output with a very flat discharge voltage plateau at all normal currents. Conversely, equally fast recharges of 10 min, or less, to 100% capacity can be realized for the same reasons. Cycle life in deep-discharge applications does not appear to be compromised by the thin foil used, as normal behaviour is observed. Applications for this high-power technology include portable-power tools, UPS systems, electrically-heated catalytic converters, repetitive pulse-power applications, and electric and hybrid vehicles
