Abstract: A lithium ion battery electrolyte, a preparation method therefor, and a use thereof. The lithium ion battery electrolyte comprises a lithium salt, an organic solvent and an additive, the organic solvent comprising a nitrile solvent. The room temperature conductivity s of the lithium ion battery electrolyte satisfies the following relational expression: 15=(K×e×?)/µ=30, K=0.02-0.07, e being the dielectric constant, ? being the mass fraction of nitrile solvent in the lithium ion battery electrolyte, and µ being the viscosity of the lithium ion battery electrolyte at room temperature. The electrolyte can effectively inhibit reductive decomposition of a nitrile solvent, and has the characteristic of weak solvation binding energy, while having relatively high ionic conductivity at low temperatures, and exhibiting relatively good rapid-charging performance. Furthermore, a battery prepared based on said electrolyte has excellent low-temperature capacity retention rate, thereby effectively improving the safety, energy density, power, rate, cycle, and other attributes thereof.
