An important secondary reaction of the Pb/PbO2 system is the one occurring at the positive electrode: 2H2 O ! O2 þ4Hþ þ 4e In a SLA cell, O2 can diffuse fast in the pores of the AGM not filled with electrolyte or in cracks of the gelled electrolyte. Therefore, it can reach the negative electrode and reform H2O: O2 þ4Hþ þ 4e ! 2H2 O This reaction is fast and allows recovering of O2 generated at the positive, thus maintaining practically unchanged H2O amount in the electrolyte. SLA batteries can be made in cylindrical or prismatic configurations.

In the bobbin structure, the amount of cathode is maximized to have high capacity and energy. Because of this structure, the cathode surface area is reduced and these cells can only be used at low drains. In the spirally wound structure, a thin layer of the cathode mix is supported on a metal grid; three strips, Li foil, separator and cathode, are tightly wound to form a high surface area structure capable of sustaining high currents. The cell cans are made of stainless steel and the separator is polypropylene.
