Herein, we tune the redox potential of 3,6-diphenyl-1,2,4,5-tetrazine (DPT) by introducing various electron-donating/withdrawing groups (methoxy, t-butyl, H, F, and trifluoromethyl) into its two peripheral benzene rings for use as electrode material in a Li-ion cell. By both the theoretical DFT calculations and the practical cyclic voltammetry (CV) measurements, it is shown that the redox potentials
在这里,我们通过将各种给电子/吸电子基团(甲氧基,叔丁基,H,F和三氟甲基)引入3,6-二苯基-1,2,4,5-四嗪(DPT)的氧化还原电位它的两个外围苯环用作锂离子电池的电极材料。通过理论DFT计算和实际循环伏安(CV)测量,结果表明1,2,4,5-四嗪(s-tetrazines)的氧化还原电势(E 1/2)与取代基的哈米特常数。在锂离子纽扣电池中,根据取代基的给电子/吸电子能力成功地调节了s-四嗪电极的放电电压。此外,发现异质电子传递速率(k 0s-四嗪分子的电导率和s-四嗪电极中的锂离子扩散率(D Li)比常规电极活性材料快得多。
