Lead-acid battery |
摘要 |
A lead-acid battery includes a positive electrode plate including a positive electrode grid and a positive active material filled in the positive electrode grid and formed in advance, a negative electrode plate 2 including a negative electrode grid 4 and a negative active material 6 filled in the negative electrode grid 4 and formed in advance, and an electrolyte solution. The positive active material contains a tin compound in an amount of 0.5% by mass to 3.0% by mass (inclusive) on a metal tin basis, and the negative active material 6 contains carbon black in an amount of 0.4% by mass to 2.0% by mass (inclusive). Shrinkage of the negative active material 6 in a thickness direction in a charge-discharge cycle is prevented to improve the charge-discharge life performance. |
