Organic quinone compounds have attracted wide attention due to their high theoretical capacities. Here, a novel cyclic macromolecular calix[6]quinone (C6Q), which possesses 6 p-quinone units and can provide 12 electrochemical active sites, has been applied as a promising cathode material in lithium ion batteries (LIBs). The as-fabricated LIBs exhibited an initial specific capacity as high as 423 mA h g⁻¹ (C_theo = 447 mA h g⁻¹) at 0.1 C. After 100 cycles, the capacity of C6Q maintained at 216 mA h g⁻¹, and even after 300 cycles, C6Q still achieved a high specific capacity of 195 mA h g⁻¹ with negligible capacity fading (as compared with the 100^th cycle). Due to the large capacity and wide electrochemical window, C6Q can deliver a specific energy up to 1201 W h kg⁻¹. In addition, the method of immobilizing C6Q with ordered mesoporous carbon (OMC) CMK-3 could further enhance the electrochemical performance of C6Q.

有机醌化合物由于其高理论容量而受到广泛关注。在这里，具有6个对苯醌单元并可以提供12个电化学活性位的新型环状大分子杯[6]醌（C6Q）已被用作锂离子电池（LIBs）中有希望的阴极材料。制成的LIB在0.1 C时表现出高达423 mA hg ^-1（C _theo = 447 mA hg ^-1）的初始比容量。100次循环后，C6Q的容量保持在216 mA hg ^-1，甚至300次循环之后，C6Q仍实现195毫安Hg的高比容量^-1具有可忽略的容量衰减（与100相比^第周期）。由于容量大和电化学窗口宽，C6Q可以提供高达1201 W h kg ^-1的比能。此外，用有序介孔碳（OMC）CMK-3固定C6Q的方法可以进一步提高C6Q的电化学性能。
