摘要 |
Disclosed is a liquid electrolyte for a lithium accumulator and the use thereof in a lithium accumulator at low temperature. The liquid electrolyte includes at least one lithium salt dissolved in a mixture of non-aqueous organic solvents. The mixture of organic solvents is formed by propylene carbonate (PC), γ-butyrolactone (GBL) and ethyl methyl carbonate (EMC). The mixture of organic solvents preferably contains between: 0.5% and 33% in volume of propylene carbonate, 0.5% and 33% in volume of γ-butyrolactone and, 0.5% and 99% in volume of ethyl methyl carbonate, the sum of the respective volume percentages of propylene carbonate, γ-butyrolactone, and ethyl methyl carbonate in the mixture being equal to 100%. |
