The invention belongs to the technical field of electrochemical energy storage, and discloses an aqueous lead-sulfur battery, which comprises a positive electrode, a negative electrode and an electrolyte, the positive electrode active material is PbSO4, the negative electrode active material is elemental sulfur, and the electrolyte is a mixed aqueous solution containing Cu < 2 + > and sulfuric acid; in the charging and discharging process, the positive electrode is subjected to PbSO4 / PbO2 conversion reaction, and the negative electrode is subjected to S / Cu2S conversion reaction. According to the invention, the sulfur negative electrode is designed to replace a negative electrode plate of the lead-acid battery and an original electrolyte of the modified lead-acid battery, so that the problem of sulfation of the negative electrode of the traditional lead-acid battery is fundamentally avoided, and the electrochemical properties such as cycle life and rate capability of the battery are greatly improved.
