Summary:

The present invention belongs to the field of secondary batteries, and discloses the application of fullerene derivatives as electrolyte additives and the corresponding metal batteries, and the fullerene derivatives are specifically added to the electrolyte of metal batteries as electrolyte additives. The invention introduces a fullerene derivative as an electrolyte additive to the electrolyte of a metal battery (in addition to the electrolyte additive of a single component composed of only fullerene derivatives, it can also be an electrolyte additive composed of a multi-component composed of fullerene derivatives in combination with other components), and obtains a corresponding metal battery, on the one hand, it can react with the metal anode to generate a stable passivation film in situ, thereby blocking the direct contact between the metal anode and the electrolyte, reducing the consumption of metal, and increasing the cycle life of the battery, On the other hand, the fullerene after the reaction will be deposited on the surface of the metal anode, so that the metal will be evenly deposited, thereby reducing the generation of dendrites and improving the safety performance of the battery.
