Amorphous Sb 2 S 3 Anodes by Reactive Radio Frequency Magnetron Sputtering for High‐Performance Lithium‐Ion Half/Full Cells

Herein, amorphous Sb 2 S 3 (a‐Sb 2 S 3 ) anodes are prepared on 3D conductive networks by a simple reactive radio frequency (RF) magnetron sputtering process, and their application feasibility in both a lithium half cell and LiFePO 4 full cell is assessed. The a‐Sb 2 S 3 electrodes exhibit excellent cycling performance and rate capacity in the half cells, owing to the amorphous phase and 3D structure, and thus yield a high discharge capacity of 585.4 mAh g −1 at a current density of 0.2 C after 250 cycles. Moreover, the assembled a‐Sb 2 S 3 /LiFePO 4 full cell can deliver 467.1 mAh g −1 at a high current density of 1000 mA g −1 even after 100 cycles. The prepared a‐Sb 2 S 3 shows great potential to be a promising alternative anode in the application of high‐electrochemical‐performance lithium‐ion batteries.
