Abstract

An electrolyte additive composition, an electrolyte, a battery, and an electric apparatus are provided. The electrolyte additive composition includes an isocyanate additive and an impedance-stabilizing additive at a weight ratio of (0.1 to 0.8):1. In the electrolyte additive composition, the impedance-stabilizing additive and the isocyanate additive are compounded, and a content ratio of the two is controlled, so that the stability of the impedance-stabilizing additive in the electrolyte can be improved, reducing the DCR of a cell of a battery and improving the stability of the DCR of the cell of the battery during charging, discharging, and storage, thereby improving the RTE of the battery during service.
