Electrolyte, battery, battery pack and electric equipment

The invention provides an electrolyte, a battery, a battery pack and electric equipment. The electrolyte comprises a first additive and a second additive, the first additive comprises a compound shown in a formula I: # imgabs 0 # formula I, and the second additive comprises a compound shown in a formula II: # imgabs 1 # formula II. According to the electrolyte provided by the invention, the specific first additive and the second additive are combined, so that the anti-overcharge protection performance of the battery is obviously enhanced, gas production of the battery can be inhibited, and the high-temperature cycle performance of the battery is effectively improved.
