ABSTRACT:
A grid is obtained by punching or expanding a sheet comprising a pure lead (Pb: 99.99 mass % or more) plate having a lead-tin alloy layer formed at least on one side of the pure lead plate. By using it as a positive electrode of a lead-acid battery, the problem that a pure lead grid shows bad charge acceptance characteristics after deep discharge can be solved, maintaining the excellent trickle life performance which a pure lead grid shows originally.
