The surface-modified effects of Zn anode with CuO in Zn-air batteries
Applied Surface Science, 2019Abstract Copper oxide nanoparticles (CuO-NPs) can be used to prevent dendrite formation and increase the reversibility of Zn anode. The zinc surface was modified with CuO and the Cu source used was copper nitrate. It also contained 0.1 wt%, 0.5 wt%, 1.0 wt%, and 3.0 wt% CuO by weight of zinc.

Tuning Zn Ion Transport Kinetics for Stable Zn Anode
With the proposed goal of carbon neutrality, the expansion of renewable energy use (wind and solar power) and the reduction of fossil fuel dependency (to curb CO2 emissions from generation) have become global priorities. Despite rapid advances in new energy technologies, energy storage remains a major bottleneck for large-scale deployment.openaire +1 more source
Achieving high-durability aqueous Zn-ion batteries enabled by reanimating inactive Zn on Zn anodes
Journal of Colloid and Interface ScienceThe heavy by-products generated on Zn anode surface decrease the active surface of Zn anodes and thus induce uneven Zn deposition, seriously reducing the service life of aqueous Zn-ion batteries (AZIBs). Herein, we propose an elimination strategy enabled by the coordination chemistry to dissolve the main by-products (Zn4SO4(OH)6·xH2O).
