随着电池在为电动车辆提供动力方面的应用增加以及对公用事业规模存储的潜在贡献，仍然需要识别和开发用于锂（Li）和钠（Na）离子电池的高效和可持续的活性材料。有机阴极材料为无机阴极材料提供了理想的替代品，而无机阴极材料通常会带来有害的环境影响和供应链的不确定性。有机材料为活性电极提供了一条可持续的途径，该活性电极还能够通过结构设计微调电化学电势。在这里，我们报告了一个双蒽醌功能化的s-引达省-1，3，5，7（2 H，6 H）-四酮（BAQIT）合成使用一个简单和廉价的路线作为高容量的正极材料用于锂离子和钠离子电池。BAQIT为Li和Na离子提供多个结合位点，同时在商业有机电解质中保持低溶解度。电化学锂离子电池表现出优异的稳定性，在0.1C倍率下300次循环后放电容量超过190 mAh g-1。该材料还显示出优异的高倍率性能，在10 C倍率下实现了142 mAh g-1的可逆容量。该材料提供上级当前最先进的有机阴极材料的高功率能力，其值达到5.09 kW kg-1。还评价了Na离子性能，在0.1C速率下90次循环后表现出130 mAh g-1的可逆容量。这项工作提供了一种结构设计，以鼓励多功能，高功率，长循环寿命的电化学储能材料。
With the increased application of batteries in powering electric vehicles as well as potential contributions to utility-scale storage, there remains a need to identify and develop efficient and sustainable active materials for use in lithium (Li)- and sodium (Na)-ion batteries. Organic cathode materials provide a desirable alternative to inorganic counterparts, which often come with harmful environmental impact and supply chain uncertainties. Organic materials afford a sustainable route to active electrodes that also enable fine-tuning of electrochemical potentials through structural design. Here, we report a bis-anthraquinone-functionalized s-indacene-1,3,5,7(2H,6H)-tetraone (BAQIT) synthesized using a facile and inexpensive route as a high-capacity cathode material for use in Li- and Na-ion batteries. BAQIT provides multiple binding sites for Li- and Na-ions, while maintaining low solubility in commercial organic electrolytes. Electrochemical Li-ion cells demonstrate excellent stability with discharge capacities above 190 mAh g–1 after 300 cycles at a 0.1C rate. The material also displayed excellent high-rate performance with a reversible capacity of 142 mAh g–1 achieved at a 10C rate. This material affords high power capabilities superior to current state-of-the-art organic cathode materials, with values reaching 5.09 kW kg–1. The Na-ion performance was also evaluated, exhibiting reversible capacities of 130 mAh g–1 after 90 cycles at a 0.1C rate. This work offers a structural design to encourage versatile, high-power, and long cycle-life electrochemical energy-storage materials.
