Abstract
A lithium sulfur battery with a low solvating electrolyte at an amount of less than 2 μl per mg sulfur. The electrolyte comprises dioxolane and hexylmethylether, as well as a Li salt, for example LiTSFi. The electrolyte is free from lithium nitrate, LiNO3.
Claims14
A battery containing an electrochemical cell comprising
- a negative lithium electrode;
- a positive sulfur electrode, the positive sulfur electrode comprising an electrically conductive porous carbon matrix having pores containing sulfur;
- a current collector abutting the positive sulfur electrode;
- a separator arranged between the negative lithium electrode and the positive sulfur electrode;
- an electrolyte arranged between the electrodes for transport of Li ions between the electrodes;
- wherein the electrolyte comprises Hexylmethylether, HME, 1,3 dioxolane, DOL, and a lithium salt, wherein the electrolyte between the electrodes is provided at an amount of less than 2 μl per mg sulfur.
