Rechargeable Zn-air batteries: Recent trends and future perspectives

1D confined materials synthesized via a coating method for thermal catalysis and energy storage applications

“…[182][183][184] Materials with high ORR and OER activity to guarantee the reversible formation of oxide species, high conductivity to enhance electron transfer, and a high specic surface area to boost the air/O 2 diffusion into the electrolyte and accommodate the discharge products are desired for MABs. [185][186][187] 1D conned electrode materials can be efficiently applied for MABs because the chemical compositions of both guest and host materials can be tailored to form bi-functional catalysts with both high ORR and OER activities, increase the specic surface area so as to expose more active sites and promote air/O 2 diffusion, improve the conductivity, enhance the structural stability and electrolyte correction resistance of carbon electrodes etc.…”

“…In the latter case, the process, together with its oxidative counterpart, that is, the oxygen evolution reaction (OER), is becoming increasingly strategic in several technological contexts. These include the perspective of designing efficient bifunctional electrodes for a novel generation of metal-air secondary batteries, , in particular with Zn anodes and aqueous electrolytes, either of the traditional alkaline type or innovative neutral ones, , as well as recently proposed solid-state ionic conductors . These devices are highly prospective for tomorrow’s green energy scenarios and enable the bypass of many issues associated with state-of-the-art Li-ion based technologies, chiefly the following: volumetric energy density, sustainability, environmental friendliness, recyclability, safety, and durability .…”

“…ZABs have been widely studied because of their high energy density (1086 W h kg À1 ), large theoretical capacity (820 mA h g À1 ), eco-friendliness, and superior security. [13][14][15][16] Conventionally, ZABs operate in alkaline electrolytes (e.g. 6 M KOH); 17 however, an extremely basic environment would corrode the containing materials, carbonize electrolyte by absorbing carbon dioxide from air, not to mention the safety and durability issues.…”
