Patent watch: ELECTROLYTE COMPOSITIONS FOR BATTERIES USING SULPHUR OR SULPHUR COMPOUNDS

Image
There are disclosed electrolytes comprising solutions of lithium salts with large anions in polar aprotic solvents with a particular concentration of background salts. The concentration of the background salts is selected to be equal or close to the concentration of a saturated solution of these salts in the aprotic solvents used. The electrolytes disclosed can be used in chemical sources of electric energy such as secondary (rechargeable) cells and batteries comprising sulphur-based positive active materials. The use of such electrolytes increases cycling efficiency and cycle life of the cells and batteries. Inventors: Vladimir KOLOSNITSYN, Elena KARASEVA  Application number: 13/153,157 Publication number: US 2011/0236766 A1 Filing date: Jun 3, 2011 Fig. 1 Charge/discharge capacity fade of standard Li-S cell Fig. 9 Charge/discharge capacity fade of Li-S cell with a saturated electrolyte solution as 1.7M of LiClO4 in methylpropylsulfone @ 0.25C ch/dch Fast...
