Organic small structure quinones go with ionic liquids electrolytes would exhibit ultrastable electrochemical properties. In this study, calix[6]quinone (C6Q) cathode was matched with ionic liquid electrolyte Li[TFSI]/[PY13][TFSI] (bis(trifluoromethane)sulfonimide lithium salt/N-methyl-N-propylpyrrolidinium bis(trifluoromethanesulfonyl)amide) to assemble lithium-ion batteries (LIBs). The electrochemical performance of LIBs was systematically studied. The capacity retention rates of C6Q through 1000 cycles at current densities of 0.2 C and 0.5 C were 70% and 72%, respectively. At 5 C, the capacity was maintained at 190 mAh g⁻¹ after 1000 cycles, and 155 mAh g⁻¹ even after 10,000 cycles, comparable to inorganic materials. This work would give a big push to the practical process of organic electrode materials in energy storage.

有机小结构醌与离子液体一起使用时，电解质将表现出超稳定的电化学性能。在这项研究中，杯[6]醌（C6Q）阴极与离子液体电解质Li [TFSI] / [PY13] [TFSI]（双（三氟甲烷）磺酰亚胺锂盐/ N-甲基-N-丙基吡咯烷鎓双（三氟甲烷磺酰基））匹配酰胺）组装锂离子电池（LIB）。系统地研究了LIB的电化学性能。C6Q在0.2 C和0.5 C的电流密度下经过1000次循环的容量保持率分别为70％和72％。在5 C下，经过1000次循环后，容量保持在190 mAh g ^-1，而在155 mAh g ^-1即使经过10,000次循环，也可以媲美无机材料。这项工作将极大地推动有机电极材料在储能中的实际应用。
