As a result, the Zn/MnO 2 battery displays excellent rate capability and cycling performance. This work will pave the way toward the design of aqueous rechargeable batteries with non﹎etallic ions.doi:10.1002/ange.202017098Shuai WangNankai University College of Chemistry CHINAZishun Yuan...
[25] took the lead in using a weakly acidic electrolyte ( ZnSO4) instead of an alkaline electrolyte to design a new aqueous rechargeable Zn-MnO2 battery. Unlike alkaline Zn-Mn batteries, some by-products, such as ZnO and Zn(OH)2, are generated on metallic Zn. New aqueous Zn-based ...
Zn-MnO2 batteries promise safe, reliable energy storage, and this roadmap outlines a combination of manufacturing strategies and technical innovations that
The NTP@Zn/MnO2 battery represents the best long﹍ife performance among Zn/MnO2 batteries to date, which successfully retains a considerable capacity of 105 mA h g1 with a CE nearly 100% after 10 000 charge/discharge cycles at 10 C (≈1.5 A g1). Each cycle capacity attenuation rate is...
