description The invention discloses an electrolyte, a positive electrode, a lithium ion battery and a vehicle. The electrolyte comprises a lithium salt, an organic solvent and an additive, the additive comprises a first additive, the first additive is a dicyano cyclic ether compound, the structural formula of the dicyano cyclic ether compound is as follows: # imgabs0 #, n, x, y and z are respectively independent positive integers, n is greater than or equal to 1 and less than or equal to 3, x is greater than or equal to 0 and less than or equal to 5, y is greater than or equal to 0 and less than or equal to 5, and z is greater than or equal to 0 and less than or equal to 5; r1 is selected from one of a hydrogen atom, a halogen atom, a C1-C5 alkane group, a C2-C5 unsaturated alkyl group, a C6-C10 aryl group or a C7-C10 alkaryl group; hydrogen atoms in C1-C5 alkyl groups, C2-C5 unsaturated alkyl groups, C6-C10 aryl groups or C7-C10 alkaryl groups can be partially or completely substituted by substituent groups.
