A new high rate lead acid battery

A new approach to the design of lead acid batteries has been developed based on the use of very thin lead foil current collectors. The basic cell construction and the performance characteristics for the new cell are described. Spiral wrap cells based on this electrode concept exhibit extremely high power output with excellent capacity maintenance. Additionally, these cells exhibit very flat voltage at all currents, and are capable of very rapid recharge. Applications for this high power technology cover a broad spectrum such as portable power tools, UPS systems, electrically heated catalytic converters, military pulse power applications and electric and hybrid vehicles.<
