PURPOSE:To lengthen life by reventing the formation of electric insulating corroded layer on the latticing material surface by the procedure in which the joint portion between a latticing material of Sb-free lead and active substance is buried in the active substance and the outside surface of the active substance is strongly pressed. CONSTITUTION:The joint portion S between the latticing material 1 of pure lead, lead-calcium alloy, or lead-strontium alloy, and the active substance 2 is buried in the active substance layer 2. And, a glass fiber mat of a fiber diameter of approx. 1mu, for example, is pressed on the plate by a pressing force of 200g/cm<2> or more to assemble an elemental cell. |
