A single crystalline Na2/3Ni1/3Mn2/3O2 microrods cathode is elaborately designed and synthesized in this work for aqueous zinc-ion batteries (ZIBs), which exhibits a reversible capacity of 130 mAh g(-1) at 5 A g(-1) after 2500 cycles. The excellent performance suggests that Ni doping modified Mn-based cathode material is a reasonable method to design high-performance ZIBs cathodes.
Aqueous zinc-ion batteries (ZIBs) receive considerable focuses due to their low flammability and high energy density. Herein, a single crystalline Na2/3Ni1/3Mn2/3O2 microrods cathode is elaborately designed and synthesized in this work for ZIBs. After 2500 cycles, it exhibits a reversible capacity of 130 mAh g(-1) at 5 A g(-1). The excellent performance suggests that Ni doping modified Mn-based cathode material is a reasonable method to design high-performance ZIBs cathodes.
