摘要： A lead-acid battery is disclosed. The lead-acid battery has a container with a cover and includes one or more compartments. One or more cell elements are provided in the one or more compartments. The one or more cell elements comprise a positive electrode, the positive electrode having a positive substrate and a positive electrochemically active material on the positive substrate; a negative electrode, the negative electrode having a negative substrate and a negative active mass on the negative substrate, wherein the negative active mass comprises a leady oxide, a synthetic organic expander, a very fine particle barium sulfate, and plurality of conductive carbons; and an absorbent glass mat separator between the positive plate and the negative plate. Electrolyte is provided within the container. A negative electrode for a lead-acid battery and a battery having improved performance are also disclosed.
