Protective layer technology for improving the cycle of Li-S based on high DN salt electrolyte |
| 초록 |
Uncontrolled growth of insulating lithium sulfide leads to pasivation of sulfur cathodes, which limits high sulfur utilization in lithium-sulfur batteries. Sulfur utilization can be augmented in electrolytes based on solvents with high Gutmann Donor Number; however, violent lithium metal corrosion is a drawback. A salt anion with a high donor number such as bromide or triflate can show better stability with lithium metal and high sulfur utilization. However, instability with lithium metal still remain compared to lithium bis(trifluoromethanesulfonyl)imide. Herein we report that why a salt anion with a high donor number have less stability at lithium anode and combination strategy can solve this problem. |
