This patent describes an electrochemical battery apparatus for producing electrical power, comprising: (a) a container for containing an electrolyte; (b) at least one bipolar electrode for generating the electrical power, which is located in the container to separate the container into a first compartment and a second compartment, the bipolar electrode comprised of (i) a base member, which is comprised of a core portion composed of titanium, an integral, substantially continuous and non-porous layer of lead, which is electroplated onto at least one face surface of the core portion and diffused a selected, limited distance into the core portion, and a substantially continuous, residual layer in the core portion that is substantially free of lead, (ii) a negative-type active mass connected to a first face surface of the base member, (iii) a positive-type active mass connected to a second face surface of the base member; (c) a positive electrode located in the first compartment of the container; (d) a negative electrode located in the second compartment of the container; and (e) sealing means for preventing leakage of electrolyte around the bipolar electrode between the first and second compartments of the container.
