The dissolution of calix[4]quinone(C4Q) in electrolytes can be inhibited by the C4Q/CMK-3(mesoporous carbon) nanocomposites prepared through perfusion method, but the electrochemical performance of the nanocomposites needs to be further improved. We prepared a serious of C4Q/CMK-3/SWCNTs(single-walled carbon nanotubes) composites with different ratio by deaerating-stirring method. In these composites, SWCNTs substituted conductive carbon blacks Super-P of the original C4Q/CMK-3 composites, which also reduced the content of CMK-3. SEM and electrochemical tests are conducted to investigate the relation of the morphology and electrochemical performance that cased by SWCNTs. The results show that the optimum mass ratio was m(C4Q):m(CMK-3):m(SWCNTs)=(1:1:1), which shows a capacity retention of 55% after 100 cycles at 0.1 C. Even at 1 C, the discharge capacity is still 260 mA·h/g. The significant improvement in the electrochemical performance could be ascribed to the formation of three-dimensional conductive network by SWCNTs.
