二次锌-空气电池锌阳极研究新进展

Zinc-air battery has attracted widespread attention due to the high theoretical energy, excellent safety and low cost, which is hopeful to be a candidate for energy storage devices in applications like electric vehicles and portable electronic devices. Zinc anode, as the key part of zinc-air battery, has many disadvantages, such as dendrite growth, shape change, passivation and hydrogen evolution etc, which limits the further development and commercialization of secondary zinc-air battery. Thus, how to solve above problems existing in zinc anode has become an research focus of zinc-air battery. The key to develop zinc-air battery includes the design and preparation of zinc anode materials with outstanding reversibility and long cycle life, which mainly concentrates on the additives, alloying, coating of zinc anode and hybrid battery. In this context, some new findings and the latest progress on the anode of zinc-based battery in recent years are introduced, which can be applied to secondary zinc-air battery.
