405 Wh kg-1 Ah-level Lithium-Sulfur Pouch Battery Stabilized over 200 Cycles by Electron-Triode-like GeS2-NiS2 Heterostructure

Lithium-sulfur batteries (LSBs) form soluble polysulfides (LiPSs) during discharge, leading to decline of cycling performance, especially the failure of pouch batteries. The failure may be since conventional sulfur hosts can...
