A cell-array battery is disclosed having end-of-life cells that can be activated at the end of a battery's life to, illustratively, neutralize the toxic chemicals inside the battery. In one embodiment, neutralization of the electrolyte in the battery is achieved through immobilization of the electrolyte at the end of the life of the battery by, for example, a vitrification process. Using electrowetting techniques, the electrolyte is made to contact a neutralizing substance between the nanostructures in one or more end-of-life cells, thus causing a reaction that results in the electrolyte becoming immobilized by, for example, a polymer substance. In a second illustrative embodiment, when the electrolyte contacts the substance between the nanostructures in one or more end-of-life cells, the chemical composition of the electrolyte is changed into a less toxic chemical compound, thus neutralizing the electrolyte.

A lead-acid battery according to the invention contains an electrode grid structure that comprises dispersoid-containing lead having relatively high strength and good corrosion resistance. The dispersoid particles exemplarily are selected from the oxides, nitrides and carbides that are substantially insoluble in lead and in sulfuric acid of concentration suitable for use in a lead-acid battery. Significantly, the dispersoid-containing lead has average grain size of at least 20 .mu.m. In consequence of the relatively large grain size, the total length of grain boundaries exposed to electrolyte is relatively small, and corrosion resistance is improved. Exemplary techniques for forming the dispersoid-containing lead are disclosed.

Metal hydrides are activated by an electrochemical procedure. In this procedure, a bulk sample of the corresponding metal is immersed in an aqueous electrolyte and contacted by a cathode. Current passed through the aqueous electrolyte causes electrolysis of the water and a concomitant reaction with the formation of metal hydride. As a result, the metal hydride is fractured and smaller particles result. Additionally, the resulting metal hydride has a substantial amount of absorbed hydrogen. A novel plating method, taking advantage of the reducing power of hydrogen absorbed in a metal hydride, is useful to encapsulate such metal hydride with a variety of metals. Therefore, such hydrides are uniformly coated by using plating solutions without the standard reducing agent and stabilizer.

Batteries based on lead chemistry, e.g., lead-acid batteries, are substantially improved through the use of a particular positive material. This material is formed by the electrochemical conversion of tetrabasic lead sulfate (TTB) where this TTB is synthesized at a pH in the range 9.3 to 12 and under reaction conditions that provide a substantial excess of sulfate to the reactive lead. The resulting materials provide needle-like structures with a width generally in the range 3 to 1 .mu.m. The relative narrow needles, when employed on the positive electrode of a lead acid battery, improve the efficiency of formation, provide good adhesive to the positive plate, extend battery life, as well as, yield excellent capacity per gram of active material.
