摘要
Abstract All‐solid‐state design is effective to address the challenges of Lithium –organic batteries, such as the dissolution of organic electrode materials (OEMs) and the safety of the Li anode. However, previous attempts, based on carbonyl‐type OEMs failed to achieve acceptable electrochemical performance in room‐temperature all‐solid‐state Li batteries (ASSLBs). Herein, the authors report the first organodisulfide cathode, poly(trithiocyanuric acid) (PTTCA), for ASSLBs. By compositing with carbon nanotubes to enhance the electronic conductivity and using the sulfide electrolyte, Li 7 P 3 S 11 , to build an electrochemically favorable interface, PTTCA demonstrates an electrochemical performance superior to all the OEMs reported so far in ASSLBs at room temperature, including a reversible capacity of 410 mAh g −1 , an energy density of 767 Wh kg −1 , and a capacity retention of 83% after 100 cycles. It is believed that this work provides new orientation and insights for the further development of both ASSLBs and OEMs.
