PROBLEM TO BE SOLVED: To provide a negative electrode lattice for lead acid battery which can prevent penetration short circuit by suppressing growth of dendrite, not relying upon coating of a lattice frame bone with an active material, but by contributing the shape of a lattice frame bone itself.SOLUTION: In a lattice frame bone 21, the ratio of the area s of a separator contact surface 21a in contact with a separator 4 to the area S of an active material contact surface 21b in contact with an active material 3 is 0.35 or less. In particular, the ratio of the area s of a separator contact surface 21a for the area S of an active material contact surface 21b is 0.2 or less. |
