Hepatocellular carcinoma(HCC)is the second most common cancer and the third leading cause of cancer-related death worldwide[1].Recently,HCC incidence and mortality rates have further increased due to changes in the global social environment and dietary habits[2].HCC is treated by surgical resection or combination chemotherapy,but the overall survival rate of HCC patients has not improved,and the recurrence rate is still high due to strong invasiveness and resistance to chemotherapy[3].

Most organic electrode materials （OEMs） for rechargeable batteries employ n-type redox centers, whose redox potentials are intrinsically limited <3.0 V versus Li+/Li. However, p-type materials possessing high redox potentials experience low specific capacities because they are capable of only a single redox reaction within the stable electrochemical window of typical ***, we report 5,11-diethyl-5,11-dihydroindolo[3,2-b]carbazole （DEICZ） as a novel p-type OEM, exhibiting stable plateaus at high discharge potentials of3.44 and 4.09 V versus Li+/Li. Notably, the second redox potential of DEICZ is within the stable electrochemical window. The mechanism of the double redox reaction is investigated using both theoretical calculations and experimental measurements, including density functional theory calculations, ex situ electron spin resonance, and X-ray photoelectron spectroscopy. Finally,hybridization with single-walled carbon nanotubes （SWCNT） improves the cycle stability and rate performance of DEICZ owing to theπ–πinteractions between the SWCNT and co-planar molecular structure of DEICZ, preventing the dissolution of active materials into the electrolyte. The DEICZ/SWCNT composite electrode maintains 70.4%of its initial specific capacity at 1-C rate and also exhibits high-rate capability, even performing well at 100-C rate.
