Lead-acid battery |
abstract |
This lead-acid battery is provided with a positive electrode board, a negative electrode plate, and an electrolyte solution. The negative electrode plate is provided with a negative electrode material. The negative electrode material contains a polymer compound. The polymer compound has a peak in the range of 3.2 to 3.8 ppm in the chemical shift of the 1H-NMR spectrum. Alternatively, the negative electrode material comprises a polymer compound containing a repeating structure of oxy C2-4-alkylene units. A ratio Cn/Sn of the content Cn of the polymer compound in the negative electrode material to the specific surface area Sn of the negative electrode material is 25 ppm・m-2・g or higher. |
