Lead storage battery |
| abstract |
The invention provides a lead storage battery comprising a positive electrode plate, a negative electrode plate and an electrolyte. The negative electrode plate described above includes a negative electrode material. The negative electrode material includes a polymer compound, and the polymer compound has a peak in the range of 3.2 ppm to 3.8 ppm in the chemical shift of the 1 H-NMR spectrum. Alternatively, the above-mentioned negative electrode material includes a polymer compound, and the polymer compound includes a repeating structure of an oxide C 2-4 alkenyl unit. The ratio of the content C n of the polymer compound in the negative electrode material to the specific surface area Sn of the negative electrode material: C n /S n is 25 ppm·m -2 ·g or more. |
