Winding type valve control sealed lead-acid battery industrialization is the key to making plate grid, the United States of America on winding valve-controlled sealed lead-acid accumulator grid manufacturing technology and equipment has been kept secret, not to export and transfer. China's independent development and design, finally solved the winding type valve-controlled sealed lead-acid accumulator grid scale production technology and equipment problems. In mass production of belt type grid products.

Winding type valve control sealed lead-acid battery used in hybrid electric vehicle battery potential, because of its good safety, quick charging, low self-discharge rate, instantaneous high output power, gas escape less, low temperature performance and shock resistance and other excellent performance, more and more attention.

Coiled lead-acid battery, mostly with lead or lead cloth as the collector, the current development of lead foam for winding type lead-acid battery. The positive electrode adopts negative grid for lead foil, such winding battery, discharge voltage, and discharge time is long, high active material utilization and quality than the capacity of its battery, regardless of the state of charge, lead foam negative electrode has an extremely low electrochemical reaction resistance, large exchange current and smaller Warburg impedance, which has higher electrochemical reaction activity.
