  "textContent": "A lead-acid battery includes a positive electrode plate, a negative electrode plate, and an electrolyte solution. The negative electrode plate includes a negative electrode material. The negative electrode material contains a polymer compound, and the polymer compound has a peak in a range of 3.2 ppm or more and 3.8 ppm or less in a chemical shift of H-NMR spectrum. Alternatively, the negative electrode material contains a polymer compound having a repeating structure of oxy Calkylene units. A ratio: C/Sof a content Cof the polymer compound in the negative electrode material to a specific surface area Sof the negative electrode material is 25 ppm·m·g or more.",
