A sealed gas recombining lead-acid cell with absorbed electrolyte is produced by assembling unformed plates and high porosity glass mat separator whose surface area is from 0.2-1.7 m2/g, adding a limited quantity of acid into the cell, and then either prior to or after sealing of the cell electrochemically forming the plates of the cell in situ. High rate performance of the cell is significantly improved over the cells using conventional high surface area glass separators.

A normally sealed gas recombining lead-acid cell having a high rate discharge capability utilizing an “oxygen cycle”comprising: a container; at least one porous positive plate and at least one porous negative plate within the container, both plates having been electrochemically formed in situ in the container; a separator material interleaved between and in firm pressure contact with the plates, comprised of a mat of microfine glass fibers having a BET surface area of from about 0.2 to about 1.5 m2/g and a porosity of from about 70 to about 98 percent; and, liquid sulfuric acid electrolyte substantially fully absorbed within the pores of the plates and separator, the quantity of electrolyte being limited such that the pore volumes of the plates and the separator are less than fully filled.
