摘要

锰基材料被认为是很有前途的水性锌离子电池（azib）阴极候选者。Mg2+掺入可以稳定MnO，促进反应动力学，提高电化学性能。此外，掺镁的MnO在2000次循环后，即使在高2a g-1速率下，也具有80.7 mAh的可逆容量。

Compositional Doping and Structure Insights for High-Performance Aqueous Zn-Ion Batteries

Mn-based materials are considered as promising cathodes candidates for aqueous Zn-ion batteries (AZIBs). Herein, Mg2+ incorporation is developed to stabilize MnO, which can promote the reaction kinetics and improve the electrochemical performance. In addition, Mg-doped MnO exhibits 80.7 mAh g-1 reversible capacity after 2000 cycles even at high rate of 2 A g-1.
