Highly conductive and stable nonaqueous electrolyte for lithium electrochemical cells

摘要

The present invention is directed towards an electrolyte which comprises a linear di-ether as a first solvent, a cyclic carbonate as a second solvent, a linear carbonate as a third solvent and a linear mono-ether as a fourth solvent. This electrolyte has improved conductivity and provides electrochemical cells with enhanced discharge performance. A most preferred electrolyte comprises 1,2-dimethoxyethane, propylene carbonate, dimethyl carbonate and diisopropyl ether.
