Summary Organic electrode materials have attracted extensive attention because of their high flexibility and sustainability, but their application was limited by the disadvantage of dissolution in conventional electrolyte. Here, we designed an all solid-state lithium-ion battery (ASSLIB) with 11,11,12,12-tetracyano-9,10-anthraquinonedimethane (TCAQ) as the cathode and lithium metal as the anode. The solid electrolyte consisted of Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 (LLZTO)/polyoxyethylene(PEO) and lithium bis(trifluoromethanesulfonimide) (LiTFSI) salt. The Li||TCAQ ASSLIB delivered a discharge specific capacity of 83 mAh g −1 at a current density of 17 mA g −1 with a capacity retention of 72.2% after 100 cycles. Our research provided a new organic cathode material for high-performance ASSLIBs.

We fabricated a potassium-ion battery by using 11,11,12,12-tetracyano-9,10-anthraquinonedimethane (TCAQ) as the cathode for the first time. Owing to the unique molecular structure and configuration of ionic liquid electrolytes, TCAQ shows a high redox potential of 2.6 V vs. K + /K while delivering a capacity of 88 mAh g −1 at a current density of 17 mA g −1 and a capacity retention of 61% after 50 cycles. The mechanism of the reaction of TCAQ with K was investigated. The results prove that TCAQ holds great promise for broad applications in potassium-ion batteries while revealing new scientific insights into K + -organic cathode batteries.
