摘要
Tetrabasic lead sulfate, 4 (PbOPbSO4)-Pb-. (4BS), was prepared from an aqueous suspension of leady oxide by using a simple hydrothermal method. Digesting the paste at a moderate temperature (125 degrees C) and heating for a short time (30 min) ensured the obtainment of particles of small, uniform size. The material was deposited on a lead alloy substrate 0.2 mm thick by spraying from aqueous suspensions. The deposits were highly uniform and homogeneous, with a coating thickness of 100 mu m. A multi-step charge algorithm involving no preliminary soaking provided the best 4BS -> PbO2 conversion. The resulting electrodes delivered a capacity of 115 Ah kg(-1) with excellent capacity retention over more than 500 cycles at 100% depth of discharge (DOD). (c) 2005 Elsevier B.V.
