Experiment design of aqueous organic flow batteries based on improved electrolyte materials

水系有机液流电池由于其丰富的原料、对环境友好和高效性已成为储能领域的主要研究对象。实验通过加布里埃尔氨合成反应合成了具有电活性吩嗪结构单元的共价有机化合物三苯并喹喔啉吩嗪二酮(HATTNQ),并对制备的HATTNQ形貌进行SEM表征。使用循环伏安法测试了HATTNQ在1 mol/L KOH碱性水溶液体系中的电化学性质,并以HATTNQ作为正极材料,组建了一个水系混合液流电池,探究其在水系液流电池系统的电池性能。该实验将吩嗪有机物在电化学研究领域的创新性研究成果引入实验化学教学,拓宽了学生的学科知识视野,提升了学生的创新实践能力和科学素养。

Aqueous organic flow batteries have become an important target of the energy storage research community due to their wide raw materials,environmental friendliness and high efficiency.In this study,an covalent organic compound,triple benzokinoxalene phenazine(HATTNQ)with electrically active phenazine building block,is synthesized by a Gabriel ammonia synthesis method.The morphology of HATTNQ is characterized by SEM.Then,the electrochemical properties of HATTNQ are tested by cyclic voltammetry in a 1 mol/L alkaline KOH aqueous solution.Subsequently,it is used as the positive material for the aqueous flow battery to study the performances of HATTNQ.This experiment introduces the innovative research achievements about phenazine organic compounds in the field of electrochemical research into the teaching of experimental chemistry,which broadened the students’perspective of subject knowledge and improved their innovative practical ability and scientific literacy.
