An electrolyte includes a compound represented by formula I-A, where A
1
, A
2
, and A
3
are each independently selected from formula I-B or formula I-C, and at least two of A
1
, A
2
, and A
3
are formula I-C. In formula I-A, n is selected from integers 1 to 10, and m is selected from 0 or 1. In formula I-B and formula I-C,
represents a site at which two adjacent atoms are joined. The electrolyte can significantly improve high-temperature storage performance, cycle performance, and floating charge performance of the electrochemical device.
