Abstract: The present invention provides a metal and metallic ion mixed battery, which contains a positive electrode, a negative electrode, and an electrolyte, the positive electrode contains a positive electrode material with a metallic component of the battery; It only coats a small amount of negative electrode active materials that can form a metallic ion battery on the negative electrode and makes the negative electrode of the battery included dual advantages of metal and metallic ion battery; when charging, the metallic ions from the positive electrode are embedded in the negative electrode active material to make the battery have the characteristics of a metallic ion battery, and then continue to deposit on the current collector to form a metal battery. After several cycles, the battery can be charged and discharged stably and retains more than 99% of Coulombic efficiency, enhancing the overall energy density of the battery.
