Metal–air batteries (MABs) offer exceptional energy density, making them attractive for vehicle electrification and storing intermittent renewable energy. However, several challenges persist, including sluggish oxygen reduction and oxygen evolution reactions, interfacial stability issues, and challenges related to current collectors. Herein, the reasons behind MAB's failures are analyzed, considering their thermodynamic aspects (Gibbs free energy, entropy), electrochemical factors (redox potentials, polarization, and ion concentrations), and kinetic properties (mobility of charges). Strategies for mitigating energy barriers of the electrodes are explored, encompassing insights into the initiation process of the oxygen reduction and determinants of oxygen evolution kinetics. The impact of humidity on the electrolyte is assessed, and effective methods for dendrite prevention are elucidated. Additionally, the utilization of 3D electrodes, oxygen‐selective membranes, solid‐state electrolytes, hybrid polymer electrodes, conductive electrocatalysts, and artificial solid‐electrolyte interfaces, and their effects on addressing the challenges faced by MABs are discussed. The study also emphasizes six critical commercialization aspects for the advancement of MABs. Lastly, the potential prospects and challenges in the field of MAB technology are discussed.

“…Porous carbon derived from biomass has been found to provide excellent ion diffusion characteristics in battery systems [79]. A few other examples are fish scale lamellae, shrimp skin, lotus petal, and crab shell structure, containing essential salts and biopolymers, which increases the mobility of ions in electrolytes while effectively inhibiting the agglomeration of nanoparticles [80][81][82][83]. The Bouligand structure of a crab shell serves as an effective host, allowing transfer of sulfur in Li-S batteries [84,85].…”

With growing environmental and ecological concerns, innovative energy storage systems are urgently required to develop smart grids and electric vehicles (EVs). Since their invention in the 1970s, rechargeable lithium-ion batteries (LIBs) have risen as a revolutionary innovation due to their superior benefits of high operating potential and energy density. Similarly, fuel cells, especially Proton Exchange Membrane Fuel Cells (PEMFC) and Solid-Oxide Fuel Cells (SOFC), have been developed as an energy storage system for EVs due to their compactness and high-temperature stability, respectively. Various attempts have been made to explore novel materials to enhance existing energy storage technologies. Materials design and development are significantly based on trial-and-error techniques and require substantial human effort and time. Additionally, researchers work on individual materials for specific applications. As a viewpoint, we present the available sustainable routes for electrochemical energy storage, highlighting the use of (i) green materials and processes, (ii) renewables, (iii) the circular economy approach, (iv) regulatory policies, and (v) the data driven approach to find the best materials from several databases with minimal human involvement and time. Finally, we provide an example of a high throughput and machine learning assisted approach for optimizing the properties of several sustainable carbon materials and applying them to energy storage devices. This study can prompt researchers to think, advance, and develop opportunities for future sustainable materials selection, optimization, and application in various electrochemical energy devices utilizing ML.
