Anion-hosting cathodes capable of reversibly storing large-size anions play a leading role in dual-ion batteries(DIBs). The purpose of the present review is to summarize the most promising anion-hosting cathodes for current and late-stage DIBs. This review first summarizes the developments in conventional graphite cathodes, especially the latest advances in the graphiterelated research. Next, organic cathodes for the anion storage are discussed, including aromatic amine polymers, heterocyclic polymers, bipolar compounds, and all-carbon-unsaturated compounds. Then, the review focuses on the conversion-type cathodes with high theoretical specific capacities. Finally, the future research directions of the cathodes of DIBs are proposed.

OBJECTIVE: To investigate the effect of Ganoderma Lucidum Spore Oil(GLSO) on the tumor growth and survival of H22 tumor-bearing mice treated with cyclophosphamide(CTX), and explore the underlying ***: Allograft H22 hepatocellular carcinoma mouse model was applied to investigate the effect of GLSO on the tumor growth and survival of animals, and Kaplan-Meier survival analysis was used to analyze the life span. Plasma biochemical examination was used to determine the levels of alanine aminotransferase(ALT),aspartate aminotransferase(AST), urea(UREA) and creatinine(CRE). Western blot analysis was performed to detect Programmed Death-1(PD-1), Programmed Death Ligand 1(PD-L1), Janus Kinase 2(JAK2),phosphorylated Signal Transducer and Activator of Transcription 3(p-STAT3), and Signal Transducer and Activator of Transcription 3(STAT3) expression. RESULTS: GLSO increased the anti-tumor effect of CTX and prolonged the survival of H22 tumor-bearing mice treated with CTX. Meanwhile, GLSO increased the thymus index and showed no obvious toxicity to liver functions of animals. GLSO also decreased the level of UREA in H22 tumor-bearing mice treated with CTX. Furthermore, GLSO could inhibit the expression of PD-1 in spleen, which was independent of JAK2 expression and STAT3 phosphorylation. However, GLSO did not affect the expression of PD-L1, JAK2, and p-STAT3 in tumor tissue. CONCLUSION: GLSO could strengthen the anti-tumor effect of CTX and prolong the life span of H22 tumorbearing mice, while the underlying mechanism might be relevant to the amelioration effect of thymus function and inhibition of PD-1 expression in spleen. Furthermore, these findings implied the promising role of GLSO in combination with CTX to extend the survival of patients in clinical chemotherapy of hepatocellular carcinoma.
