Abstract:
Herein, hollow sulfur spheres encapsulated hermetically by FePS3 flakes (HSS@FePS3) are utilized in lithium sulfur batteries (LSBs). Via the encapsulation, soluble polysulfide can be trapped obviously and volume expansion during discharge can be accommodated effectively. The HSS@FePS3 cathode shows an excellent cycling stability even at a current density of 1C (a capacity decay of 0.0461% per cycle during 1000 cycles).
