  • Lead-titanium, bipolar electrode in a lead-acid battery
    Patent number: 4683648
    Abstract: A bipolar electrode for generating electrical power in an electrochemical cell includes a base member, which is comprised of a core portion composed of titanium. An integral, substantially continuous and non-porous layer of lead is electroplated onto at least one face surface of the core portion and diffused a selected distance into the core portion. A substantially continuous, residual layer of the titanium alloy in the core portion remains substantially free of lead. A negative-type active mass is connected to a first face surface of the base member, and a positive-type active mass is connected to a second face surface of the base member.
