The alpha-MnO2/super-P composite, synthesized via in-situ hydrothermal method, exhibits excellent discharge capacity and coulombic efficiency in aqueous Zinc ion battery, mainly due to the short diffusion path of Zn2+ and the largescale conductive network of conductive carbon (super P) particles.
High crystallinity, nano size, and full contact with conductive media are essential for improving the performance of battery materials. Herein, alpha-MnO2/super-P composite is synthesized via in-situ hydrothermal method. As the cathode material of aqueous Zinc ion battery, the alpha-MnO2/super-P was maintained 47.0% of discharge capacity after 1000 cycles (decreased from 180 mAh g(-1) in the first cycle to 84.6 mAh g-(1) in the 1000th cycle) at a high rate of 1.0 A g(-1) and reaches the coulombic efficiency to 100% throughout the whole cycles. The excellent electrochemical performance of alpha-MnO2/super-P is mainly due to the short diffusion path of Zn2+ and the largescale conductive network of conductive carbon (super P) particles.
