LITHIUM-SULPHUR CELL |
| 摘要 |
A lithium-sulphur cell comprising an anode comprising lithium metal or lithium metal alloy, a cathode comprising a mixture of electroactive sulphur material and solid electroconductive material, an electrolyte comprising a tetrafluoroborate salt and an organic solvent, wherein the tetrafluoroborate salt is present in the electrolyte at a concentration of 0.05 to 0.5M, and wherein the tetrafluoroborate salt is present in an amount, wherein the molar ratio of tetrafluoroborate anion, BF4, to sulphur, S, in the electroactive material is 0.009-0.09:1. |

1. A lithium-sulphur cell comprising:
an anode comprising lithium metal or lithium metal alloy, a cathode comprising a mixture of electroactive sulphur material and solid electroconductive material, an electrolyte comprising a tetrafluoroborate salt and an organic solvent, wherein the tetrafluoroborate salt is present in the electrolyte at a concentration of 0.05 to 0.5M, and wherein the tetrafluoroborate salt is present in an amount, wherein the molar ratio of tetrafluoroborate anion, BF4−, to sulphur, S, in the electroactive material is 0.009-0.09:1. |
