摘要 | delta-MnO2 was proposed as a promising cathode material for aqueous Zn-ion batteries. Nonetheless, its potential application has been impeded by its unstable crystal structure and sluggish reaction kinetics with Zn ions. Herein, we utilized Cr to modify delta-MnO2 by a simple hydrothermal method to develop cathode materials for aqueous Zn-ion batteries with better stability and electron transport properties. The introduction of Cr enhanced the specific capacity and cycling stability of delta-MnO2, in particular, the 3% Cr doped delta-MnO2 electrode exhibited a large specific capacity of 229.2 mAh |
