Phosphorus/nitrogen co-doped and bimetallic MOF-derived cathode for all-solid-state rechargeable zinc–air batteries

Abstract

The bimetallic FeNi-MOFs are employed to fabricate P–FeNi and N–carbon co-doped bifunctional catalyst. Due to the enhanced catalytic performance, the peak power density of all-solid-state zinc–air battery is 159 mW cm−2.

A hybridization cage-confinement pyrolysis strategy for ultrasmall Ni3Fe alloy coated with N-doped carbon nanotubes as bifunctional oxygen electrocatalysts for Zn–air batteries

“…[1][2][3] Among all the candidate batteries, the Zn-air battery (ZAB) is expected to be the next generation of global battery due to its unique semi-open system, signicant theoretical energy density, exible electrodes, environmental friendliness, and abundant resources. 4,5 However, the kinetics of the oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) of ZABs in the process of charging and discharging is sluggish, resulting in high overpotential, low roundtrip efficiency, low cycle life, and energy conversion efficiency, which are the major bottlenecks for large-scale commercial applications of ZABs. [6][7][8] Noble metal Pt-based and Ru-and Irbased catalysts are considered to be effective catalysts for the ORR and OER, respectively.…”

Investigation of the cycling stability and energy storage properties of zinc titanate (ZnTiO3) perovskite material for zinc–air batteries

“…Also, because of their high catalytic activity, perovskites are highly durable for the OER in alkaline conditions. 16,17 Perovskites show effectiveness in the fields of thermostable glasses (showing application in blue lasers), 18 capacitors 19,20 and other energy storage applications. 21…”

“…Perovskites (molecular formula -ABO 3 ) benefitting from the arrangement of transition metals (e.g., Mn, Co, Ni) with rare-earth metals and oxygen have recently received a lot of attention as rich sources for the intentional design of effective, bifunctional and non-precious metal catalysts for zinc-air batteries. 16 They have controllable functionalities, adsorption affinity, and a high surface area due to their open three-dimensional structure, making them a viable option. Also, because of their high catalytic activity, perovskites are highly durable for the OER in alkaline conditions.…”

Nanofiber Composite for Improved Water Retention and Dendrites Suppression in Flexible Zinc‐Air Batteries

“…Flexible and rechargeable ZABs are promising power supply sources for next-generation wearable electronic devices due to the merits of low cost, high energy density (1086 Wh kg −1 ), and nontoxicity. [1][2][3][4] Traditional flexible and rechargeable ZABs are sandwich structures consisting of zinc anode, solid-state polymer electrolyte, and open-air cathode. [5,6] In general, GPEs are widely used in the ZABs due to their advantages of high water retention and easy preparation.…”
