In situ growth of ZnO nanosheets on Ti3C2Tx MXene for Superior-Performance Zinc-Nickel secondary battery

ZnO quantum dots@covalent organic frameworks for high-performance alkaline zinc-based batteries

“…57 Even from 3800 to 3820 cycles (Fig. 5e), the voltage level remains as stable as the initial level, indicating that the introduction of the TpPa-1 COF reduces the occurrence of side reactions and alleviates the polarization phenomenon, 58 which proves that the material has good stability. To further illustrate the effects of ZnO QDs and the TpPa-1 COF on the morphological changes of the anode, the SEM images and corresponding mapping of the electrodes in different cycles were collected.…”

ZnO@NC/CNT as Anodic Material for Zinc Nickel Secondary Batteries with Ultra-High Stability and Long Cycle Life

“…The oxidation peak of the three materials is stronger than the reduction peak due to the overlap of the hydrogen precipitation peak and the reduction peak. The conversion equations for the charging and discharging process are as follows: …”

“…The oxidation peak of the three materials is stronger than the reduction peak due to the overlap of the hydrogen precipitation peak and the reduction peak. The conversion equations for the charging and discharging process are as follows: 0.25em ZnO + 2 normalO normalH − + normalH 2 normalO → Zn false( OH false) 4 2 − 0.25em Zn false( OH false) 4 2 − + 2 normale → Zn + 4 normalO normalH − …”

ZnO@ATO as an Anode Material to Achieve Ultra-long Stable Cycling for Zinc–Nickel Secondary Batteries

“…As an emerging material with a charged surface, MXene is not only used for the construction of 2D nanofluidic membranes but also used as a substrate material for the modification of zinc anodes. 17,18 In addition, replacing zinc oxide with calcium zincates, 19 layered double hydroxides, 20 and layered double oxides 21 as new active materials for zinc−nickel batteries can enhance the stability of electrode cycling and alleviate the self-corrosion of zinc anodes to a certain extent. Although these strategies have been proven to have a positive effect on improving the cycle life of batteries, the defects of zinc−nickel batteries are difficult to be solved in a focused and comprehensive manner.…”

“…Metal oxides (such as Bi 2 O 3 and In 2 O 3 ) are added to the zinc anode to raise the hydrogen evolution potential of the electrode, thereby inhibiting the corresponding side reactions. , The conductivity of zinc anodes can be increased by using conductive materials as substrates or by coating the active material surface with metal monomers, , which can effectively inhibit electrochemical polarization. As an emerging material with a charged surface, MXene is not only used for the construction of 2D nanofluidic membranes but also used as a substrate material for the modification of zinc anodes. , In addition, replacing zinc oxide with calcium zincates, layered double hydroxides, and layered double oxides as new active materials for zinc–nickel batteries can enhance the stability of electrode cycling and alleviate the self-corrosion of zinc anodes to a certain extent.
