Nitrogen-linked hexaazatrinaphthylene polymer (N -HATN) as organic cathode material with low HOMO-LOMO gap was synthesized and was observed to possess reversible high capacity and unexpected long-term cycling stability. The pre-treated N -HATN and pRGO combination demonstrated good structure compatibility and the resultant cathode exhibited a constant increment of capacity during the redox cycles. The initial capacity at 0.05 A g was 406 mA h g , and increased to 630 mA h g after 70 cycles. At 0.5 A g discharging rate, the capacity increased from an initial value of 186 mA h g to 588 mA h g after 1600 cycles. The pseudocapacitance-type behavior is postulated to be attributed to the structure compatibility between the active material and pRGO.
合成了具有低HOMO-LUMO能隙的氮连接六氮杂三萘聚合物(N-HATN)作为有机阴极材料,并观察到其具有可逆的高容量和意想不到的长期循环稳定性。预处理后的N-HATN与pRGO的组合表现出良好的结构相容性,所得阴极在氧化还原循环中容量持续增加。在0.05 A g时的初始容量为406 mA h g,70次循环后增加到630 mA h g。在0.5 A g的放电速率下,容量从初始值186 mA h g在1600次循环后增加到588 mA h g。推测赝电容型行为归因于活性材料与pRGO之间的结构相容性。
