Material design and surface chemistry for advanced rechargeable zinc–air batteries

Abstract

Zinc-air batteries (ZABs) have been considered as a next-generation battery system with a high energy density and abundant resources. However, the sluggish multi-step reaction of the oxygen is the main...

Bifunctional Nb-N-C atomic catalyst for aqueous Zn-air battery driving CO2 electrolysis

“…Conversely, during the charging process, oxygen and zinc metal regenerate (backward Reactions (1) and ( 2)). The reaction involved in a ZAB is illustrated as follows [61,62]:…”

Bifunctional BiPd Alloy Particles Anchored on Carbon Matrix for Reversible Zn–CO2 Battery

“…Moreover, the aqueous zinc batteries are applied extensively, attributed to their high safety, lower cost, and high theoretical capacity of zinc (820 mA h g –1 ). − The discharge process of ZAB can be assumed that zinc electrode dissolution drives cathodic ORR along with anodic Zn metal forming zincate ions (Zn­(OH) 4 2– ) and further decomposing to insoluble zinc oxide (ZnO). Oppositely, extra electricity powers oxygen and zinc metal to regenerate during the charging process. , Inspired by the reversible oxygen-reduction and oxygen-evolution reactions (ORR and OER) of ZAB, the emerging reversible Zn–CO 2 battery (ZCB) system based on CO 2 –HCOOH interconversion was proposed for simultaneously releasing electricity and converting CO 2 into value-added resources (e.g., hydrocarbon and alcohol) . Unlike other kinds of battery systems, ZCBs are inclined to transform CO 2 into value-added chemical production instead of providing electricity .…”

Surface chemistry and structure manipulation of graphene-related materials to address the challenges of electrochemical energy storage

“…Among metal-air batteries, rechargeable ZABs get attention due to their high theoretical energy density (1086 W h kg À1 ), excellent safety (aqueous electrolyte), unique open structure and abundance of zinc in earth's crust, consuming atmospheric oxygen as a cathodic active material. 4 However, ZABs currently suffer from poor cycling stability and inferior charging/discharging rates. Another interesting idea for aeronautics and automotive sectors is the use of structural batteries, i.e.…”
