Electrolyte, and electrochemical device and electronic device comprising the same

An electrochemical device, comprising a positive electrode, a negative electrode, a separator, and the electrolyte comprising at least a compound of formula I:

• wherein A1, A2, and A3 are each independently selected from the following formulas I-A, I-B, I-C, or I-D, and the A1, A2, and A3 are not all I-A:
• wherein
• represents a binding site for binding to an adjacent atom,
• wherein m and k are each independently selected from 0 or 1, and n is selected from integers 1 to 6,
• wherein R11, R13, R14, R15, R16, R17, R18, R19, R1a, R1b, R1c, and R1d are each independently selected from hydrogen, substituted or unsubstituted C1-C10 alkylidene groups, substituted or unsubstituted C2-C10 alkenylene groups, substituted or unsubstituted C2-C10 alkynylidene groups, substituted or unsubstituted C3-C10 cumulative dienyl groups, substituted or unsubstituted C6-C10 aryl groups, or substituted or unsubstituted C3-C10 alicyclic hydrocarbon groups;
• and
• R12 is selected from substituted or unsubstituted C1-C10 alkyl groups, substituted or unsubstituted C2-C10 alkenyl groups, substituted or unsubstituted C2-C10 alkynyl groups, substituted or unsubstituted C3-C10 in cumulative dienyl groups, substituted or unsubstituted C6-C10 aryl groups, substituted or unsubstituted C3-C10 alicyclic hydrocarbon groups, or substituted or unsubstituted heteroatom-containing functional groups,
• wherein when substitution is performed, substituents are each independently selected from halogens.
