Organic electrolyte for lithium-ion battery and lithium-ion battery comprising the same
Disclosed are an organic electrolyte for a lithium-ion battery and a lithium-ion battery comprising the same, wherein the electrolyte includes a base electrolyte containing a lithium salt dissolved in an organic solvent, and diphenyloctyl phosphate added thereto in an amount of 0.1 to 20 wt %. As compared to a conventional organic electrolyte using only a carbonate ester-based solvent, such as ethylene carbonate, ethyl methyl carbonate, etc., the lithium-ion battery employing the organic electrolyte can improve thermal stability of an electrolyte solution, high-rate performance, and charge/discharge cyclability of a battery, while maintaining battery performance of the base electrolyte.
