中山大学余丁山教授 & 广西大学朱园勤教授研究论文——Long-lifespan aqueous alkaline and acidic batteries enabled by redox conjugated covalent organic polymer anodes
在本期封面文章中,中山大学余丁山教授课题组与广西大学朱园勤教授课题组合作,构筑了一种兼具氧化还原活性、超亲水性和宽pH适应性的共价有机聚合物(COP) 作为酸性和碱性水系电池的长寿命负极材料。传统无机负极材料难以同时具备对酸性和碱性电解液的耐受性,且在反应过程中易产生溶解、腐蚀或枝晶等问题,严重制约了电池循环寿命的提升。COP的无定形交联网络和扩展共轭结构能够赋予其畅通的离子和电子传输通道以及优异的酸碱共耐受性,因此展现出了快速的表面控制氧化还原反应动力学以及在单电极和全电池体系中一致的超高稳定性。该项研究为用于酸性和碱性水系电池的高性能和长寿命聚合物电极的结构设计和实际应用提供了理论指导。
