Zinquinone hybrid for the anode of drainage potassium ion battery

Based on the development of energy materials, phenazine (PNZ) and its analogues were selected as the development target, and the high purity TAPQ was obtained through actual synthesis. The resulting TAPQ was applied to strong alkaline conditions (6 M KOH). Through actual assembly and debugging, and cyclic voltammetric test, it was found that the specific capacity was 370 mAh g-1 at the current capacity of 0.1 A g-1, and the ratio ratio was still maintained 100%. Meanwhile, the redox reaction of TAPQ was found to be step by step with high reversibility. At the same time, the full cell cycle voltammogram shows that TAPQ has good cycle stability in actual operation. Based on the performance results of the detection and the comparative analysis of the current data, the practical application of TAPQ provides a new idea for exploring new organic electrode materials.
