| abstract | An electrolyte, a secondary battery, a battery module, a battery pack and a device. The electrolyte comprises a lithium salt, an organic solvent and an additive. The additive comprises nitrogen. Nitrogen is added into the electrolyte, such that oxygen and carbon dioxide can be effectively removed, reducing the impedance of a battery. Lithium precipitated during use of a battery can react with nitrogen in the electrolyte to produce Li 3N, and Li 3N due to high activity of the precipitated lithium, and thus will prevent direct contact between electrons and lithium ions caused by a low potential in a lithium precipitation region, so as to prevent the spread of lithium precipitates, passivate lithium precipitates, and extend the service life of a battery during use, while also avoiding safety issues in which lithium dendrites are produced during extended use. The battery module, the battery pack and the device comprise the secondary battery and thus at least have the same advantages as those of the secondary battery. |
