PURPOSE:To make the promotion of improvement for initial and life performance, by divisionally applying a paste, consisting of lead powder with highly apparent density, and a paste, consisting of lead powder with low apparent density, to the top and bottom portion. CONSTITUTION:In a top portion 1/2 of a lattice unit 1, is filled a paste 2, consisting of fine lead powder (lead powder with high apparent density), and in a bottom portion 1/2 of the lattice unit, is filled a paste 3, consisting of coarse lead powder (lead powder with low apparent density). In such constitution, an excellent plate can be obtained both for initial performance and charge-discharge cycle performance. |
