Abstract
The present invention provides a battery, including a cathode, a anode, and an electrolyte solution. The cathode includes a cathode active substance and a cathode current collector. The electrolyte solution includes first metal ions and second metal ions. In a charging/discharging process, the first metal ions can be reversibly deintercalated-intercalated at the cathode, the second metal ions can be reduced and deposited as a second metal at the anode, and the second metal can be oxidized and dissolved back to the second metal ions. The anode includes a anode active substance and a anode current collector. A lead-containing substance is provided on a surface of the anode active substance and/or in the electrolyte solution. A mass ratio of lead in the lead-containing substance to the battery is not greater than 1000 ppm. The present invention can effectively improve a dendrite problem at a anode of a battery, prolong the cycle life of the battery, and improve the electrochemical performance and safety performance of the battery.
