environmental concerns. In this context, developing the chemistry of anion-inserting electrode organic materials could promote the fabrication of molecular (metal-free) rechargeable batteries. However, few examples have been reported because little effort has been made to develop such anionic-ion batteries. Here we show the design of two anionic host electrode materials based on the N-substituted salts
对可充电电池的不断增长的需求给全球金属供应带来了巨大压力,资源枯竭,成本和环境问题日益严重。在这种情况下,开发插入阴离子的电极有机材料的化学性质可以促进分子(无金属)可充电电池的制造。但是,由于开发这种阴离子电池的努力很少,因此报道的例子很少。在这里,我们展示了基于氮杂芳香族化合物(两性离子)的N-取代盐的两种阴离子主体电极材料的设计。NMR,EDS,FTIR光谱学结合热分析和单晶XRD可以对化合物进行彻底的结构和化学表征。由于平均电位为2时具有可逆的电化学活性。
