Abstract :
The authors report studies on the influence of low temperature on the properties and cycling performance of six selected electrolytes. The electrolytes investigated were 2-MeTHF, EC/2-MeTHF, THF, THF/2-MeTHF, EC/THF, and EC/THF/2-MeTHF. All the electrolytes contained 1.5 M LiAsF 6. Open circuit stand tests indicated that organic electrolytes exhibited improved stability towards lithium at 10°C. However, cycling of the cells at 10°C did not result in improved cycle life performance
