Lead acid battery having cellular matrix positive electrode

In a lead-acid electrolyte battery, an improved positive electrode comprising:

• an electrically conducting current collector bus plate;
• a honeycomb matrix structure extending from one side of said collector bus plate forming multiple positive active material compartments and having electrically conducting surfaces in electrical communication with said collector bus plate;
• an acid ion porous retainer means adjacent the ends of said material compartments opposite said collector bus plate and in contact with said acid electrolyte;
• and positive active material within said compartments and in electrical communication with said collector bus plate and said honeycomb matrix electrically conducting surfaces, said positive active material comprising lead oxide reactive material and powdered electronic conductive additive resistive to electrolyte corrosion throughout a stable acid ion porous structure, the acid ions of the electrolyte passing through said retainer means and contacting said reactive material to produce electronic flow whose conductance to said honeycomb matrix structure and said current collector bus plate is increased by said conductive additive.

A process for obtaining high rate discharge from a lead-acid battery comprising:

• passing acid ions of an acid electrolyte through an acid ion porous retainer means to contact positive active material;
• reacting said acid ions with said positive active material comprising lead oxide thereby producing electronic flow;
• increasing the conductance of said electronic flow through said positive active material to an electrically conducting surface of a honeycomb matrix structure positive active material retention compartment and to an electrically conducting current collector bus plate by a powdered conductive additive throughout said positive active material within a stable acid ion porous structure;
• conducting said electronic flow through said honeycomb matrix structure to said current collector bus plate, and withdrawing said electronic flow from said current collector bus plate to produce high rate discharge.
