NiCo2O4 for alkaline Zn-based batteries (AZBs) suffers from low capacity and an unsatisfactory cycling life. Meanwhile, the widespread application of is seriously limited by costly tedious synthetic procedures. In this work, a facile economically efficient surface corrosion strategy demonstrated to fabricate high-performance Mn-doped (SMNC) nanosheet cathode AZBs. Compares undoped (SNC), SMNC shows enhanced mass transfer ability increased active sites. Consequently, Zn/SMNC cell reaches big areal 0.58 mA h cm–2 at 2 as well ultralong cycle life with 95% retention over 6000 cycles. This work provides effective, low-cost, method prepare advanced materials

Due to the continuous depletion of lithium resources and security risks organic electrolytes such as combustion explosion, there is an imminent requirement develop a type energy accumulation system adapt progression progress society. Zinc-ion batteries using aqueous electrolyte have advantages high safety, low cost, environmental friendliness, which make them ideal alternative lithium-ion next-generation storage system. Among zinc-ion battery cathode materials, manganese-based materials carbon occupy main positions, respectively. them, nickel manganate (NiMn2O4) nanosheets nanotubes (CNTs) active received extensive attention. The CNTs could provide electronic conductive channels NiMn2O4 supply more points for electrochemical reactions. shell with porous structure also improves electron transport ionic conduction processes, so that manganate/carbon nanotube (NiMn2O4/CNTs) nanocomposites obtained specific capacitance 333.6 mAh g–1 at current density 0.2 A g–1. After 500 cycles 0.5 led capacity 73.6 g–1, it was shown material exhibits excellent comprehensive properties. This synergistic strategy combining structural design activation in NiMn2O4/CNTs can be reference other materials.
