| 英文摘要 | Due to the intrinsic poor ionic/electronic conductivities of Li2S, it is a great challenge to realize high-rate all-solid-state lithium-sulfur batteries (ASSLSBs) with long cyclic performance. Herein, ultrasmall Li2S (similar to 15 nm) is evenly deposited on a carbon nanotube (CNT) via a facile liquid-phase method to address these issues. The unique structure of the Li2S deposited on a CNT composite cathode can improve ionic/electronic conductivities of Li2S effectively and relieve the generated internal stress/strain during cycling. Specifically, the resultant Li/75%Li2S-24%P2S5-1% P2O5/Li10GeP2S12/Li2S-53%CNT ASSLSBs show a reversible capacity of 651.4 mAh g(-1) under 1.0C at 60 degrees C after 300 cycles and even at a much higher cathode load of 5.08 mg cm(-2), a high discharge capacity of 556 mAh g(-1) can still be obtained under 0.1C after 20 cycles. The outstanding electrochemical performances are also attributed to the high diffusion coefficient of Li2S-53%CNT, which is 39 times that of pristine Li2S. This work presents an efficient procedure to design cathode materials with high ionic/electronic conductivities and paves the way for the successful commercialization of high-rate ASSLSBs. |
