H2O–H–Na co-intercalation is beneficial to enhance the structure of open framework V-based materials, leading to the improvement of Zn2+ transport kinetics and solid-state solubility in V-based electrodes. Zn|Zn(CF3SO3)2|HNaV6O16·4H2O exhibits an excellent specific capacity of 432.4 mA h g−1 and a long-term cyclic performance up to 800 cycles at 2.0 A g−1 with a reversible phase transformation. For the fast charge capability, a high specific capacity of 411.2 mA h g−1 is achieved with a coulomb efficiency of 100%. The co-intercalation structure can provide a new strategy for the design of fast charge cathode materials in aqueous zinc ion batteries (AZIBs).

一种用于快速充电水性锌离子电池的共嵌入增强型钒基正极材料
H 2 O-H-Na 共嵌入有利于增强开放骨架 V 基材料的结构，从而改善V 基电极中的 Zn 2+传输动力学和固态溶解度。Zn|Zn(CF 3 SO 3 ) 2 |HNaV 6 O 16 ·4H 2 O 表现出优异的比容量 432.4 mA hg -1和在 2.0 A g -1 下长达 800 次循环的长期循环性能，具有可逆性相变。对于快速充电能力，411.2 mA hg -1的高比容量库仑效率达到 100%。共嵌入结构可以为水性锌离子电池（AZIBs）中快速充电正极材料的设计提供新的策略。
