Abstract

Rapid capacity decay and sluggish reaction kinetics are major barriers hindering the applications of manganese-based cathode materials for aqueous zinc-ion batteries. Herein, the effects of crystal plane on the in-situ transformation behavior and electrochemical performance of manganese-based cathode is discussed. A comprehensive discussion manifests that the exposed (100) crystal plane is beneficial to the phase transformation from tunnel-structured MnO2 to layer-structured ZnMn3O7·3H2O, which plays a critical role for the high reactivity, high capacity, fast diffusion kinetics and long cycling stability. Additionally, a two-stage zinc storage mechanism can be demonstrated, involving continuous activation reaction and phase transition reaction. As expected, it exhibits a high capacity of 275 mAh g−1 at 100 mA g−1, a superior durability over 1000 cycles and good rate capability. This study may open new windows toward developing advanced cathodes for ZIBs, and facilitate the applications of ZIBs in large-scale energy storage system.

晶面诱导的锰基阴极原位电化学活化实现了长期水性锌离子电池
快速的容量衰减和缓慢的反应动力学是阻碍锰基阴极材料在水性锌离子电池中应用的主要障碍。本文讨论了晶面对锰基阴极原位转化行为和电化学性能的影响。综合讨论表明,暴露的(100)晶面有利于从隧道结构的MnO2向层结构的ZnMn3O7·3H2O的相变,这对高反应性、高容量、快速扩散动力学和长循环稳定性起着关键作用。此外,还可以证明锌的两阶段储存机制,包括连续活化反应和相变反应。正如预期的那样,它在100 mA g−1下表现出275 mAh g−1的高容量,在1000次循环中具有卓越的耐用性和良好的倍率性能。这项研究可能为开发先进的ZIBs阴极打开新的窗口,并促进ZIBs在大规模储能系统中的应用。
