甲基增强的高性能亚胺类锌离子电池正极材料
High-performance imine cathode materials of zinc-ion batteries enhanced by methyl groups
摘要
Abstract
Organic compounds are widely used as cathode materials for zinc-ion batteries due to their high capacity and excellent performance.However,low specific capacity and short cycle life limit their developments.Therefore,a compound hexamethyl-hexaazatrinaphthalene(HATN-Me)with C=N(imino)functional group and polymethyl structure is designed.The fabricated zinc-ion battery still has a capacity retention rate of 87％after more than 7 000 cycles at current density of 1 A/g.Ex-situ analysis proves that C=N is the active center,and the polymethyl structure effectively enhances the electron transport performance.Prospectively,HATN-Me cathode material with excellent electrochemical performance and stability will promote the development of aqueous zinc-ion batteries.关键词
