| abstract |
The present invention relates to a non-aqueous electrolyte for a lithium secondary battery in which an electrolyte salt is dissolved in a non-aqueous solvent, and the 1,2-cyclohexanediol derivative having a specific structure in the non-aqueous electrolyte is a non-aqueous electrolyte. Is a non-aqueous electrolyte characterized by containing 0.01 to 30% by weight, and a lithium secondary battery using the non-aqueous electrolyte, and has battery characteristics such as electric capacity, cycle characteristics, and storage characteristics. Excellent and battery performance can be maintained for a long time. |
