A positive electrode 10 for a lead acid electric storage cell 24 is made by chemically preparing beta lead dioxide. The beta lead dioxide is then applied to a support structure 14 with a binder, or poured into a permeable, tubular container located about a current collecting rod. The negative electrode 26 can be made by compacting fine lead metal 30 about a carrier 32, and the fine lead metal might comprise lead wool or particulate lead metal.
