PURPOSE:To obtain the captioned battery whose energy density during high output discharge is enhanced and whose life performance is improved, by lowering the apparent density of the positive active material and by using as the separating part a ribbed or a corrugated, finely perforated plate. CONSTITUTION:In a power lead storage battery, a positive plate where the apparent density of the positive active material is 3.2g/cm<3> is employed. Also, in the separating part, a ribbed plate or a corrugated, finely perforated plate is employed separately. Furthermore, the grid frame structure of the positive electrode plate is made to be Japanese shoji-like (paper sliding door) and the thickness shall be less than 1.0mm.. Consequently, generation of high output and also reduction of the weight of the lead storage battery can be achieved without lowering the power characteristic thereof. |
