Research and development on electrochemical energy storage and conversion (EESC) devices, viz. fuel cells, supercapacitors and batteries, are highly significant in realizing carbon neutrality and a sustainable energy economy. Component corrosion/ degradation remains a major threat to EESC device's long-term durability. Here, we provide a comprehensive account of the EESC device's corrosion and degradation issues. Discussions are mainly on polymer electrolyte membrane fuel cells, metal-ion and metal-air batteries and supercapacitors. Corrosion of bipolar plates/current collectors, carbon corrosion, electrode/ electrocatalyst degradation, and various mitigation approaches are detailed. The collective information provided could help develop EESC devices with better durability.

“…Besides, the aforementioned issues with metal anodes are also being addressed through the introduction of heavy metals, carbon, and surfactant additives. [117,[147][148][149][150] In general, compared with air cathodes of wearable aqueous metal-air batteries, research achievements in metal anodes are relatively few. Thus, more efforts should be made to optimize the mechanical and electrochemical performance of the metal anode of wearable aqueous metal-air batteries.…”

The advent of the information age has promoted the development of smart wearable electronics for acquiring real-time data, such as smart bracelets, real-time health monitors, electronic skins, and smart clothes, [1][2][3][4][5][6][7][8][9] which has in turn promoted the development of power supply systems with high operational safety, long cycle life, high energy, and excellent deformability. Among recently developed flexible power supplies, [10][11][12][13][14] flexible lithium-ion (Li-ion) batteries have been dominantly employed in wearable electronics because of competitive chargedischarge efficiency (≈90%), high energy density (≈400 W h kg −1 ), durable cycling life (≈5000 cycles) and mature Li-ion battery infrastructure. [15] Moreover, wearable fiber Li-ion batteries can be woven into textiles, offering a convenient way to power wearable electronics. [16][17][18] Nonetheless, the safety and environmental risks caused by the usage of flammable/ toxic organic electrolytes restrict the further advance of Li-ion batteries and make them unsatisfied to be integrated with wearable electronic devices in proximity to the human body. [15,19] Further efforts are highly demanded to explore alternative power systems with promising energy density, reliable discharge-charge characteristics, long operation life, and good safety.In recent years, metal-air batteries have received widespread attention because of their remarkable theoretical energy density, environmental-friendliness, low fuel cost, and superior safety. [20][21][22][23] In particular, their unique half-open systems can continuously utilize the oxygen from ambient air instead of storing gaseous oxygen in closed systems, thus the required mass and volume of the air electrode can be largely minimized, resulting in high theoretical energy densities. [24] Compared to the theoretical energy density of Li-ion batteries with a closed system (460 Wh kg −1 ), lithium-air (Li-air) batteries exhibit much higher theoretical energy density (≈3500 W h kg −1 , based on the discharge product of Li 2 O 2 ). [25,26] Flexible wearable metal-air batteries, combining the flexible deformation feature and the high theoretical energy density, have become attractive energy supply systems for wearable electronic devices. Since 2015, wearable metal-air batteries (i.e., zinc-air (Zn-air), Li-air, aluminum-air (Al-air), sodium-air (Na-air), potassium-air (K-air), With the increasing popularity of personal wearable electronic devices used for healthcare, entertainment, and sports applications, the corresponding energy supply and space adaptability of devices are required to meet higher standards. Owing to large energy densities and intrinsic safety, wearable aqueous metal-air batteries have shown great potential to be energy storage/ conversion integrated systems for wearable electronic devices characterized by long-term low-power operation. In contrast to non-aqueous electrolytes, aqueous-based electrolytes exhibit greater ionic conductivity, higher operational safety, lower cost, and super...

Nitrogen (N) doping of graphene with a three‐dimensional (3D) porous structure, high flexibility, and low cost exhibits potential for developing metal–air batteries to power electric/electronic devices. The optimization of N‐doping into graphene and the design of interconnected and monolithic graphene‐based 3D porous structures are crucial for mass/ion diffusion and the final oxygen reduction reaction (ORR)/battery performance. Aqueous‐type and all‐solid‐state primary Mg–air batteries using N‐doped nanoporous graphene as air cathodes are assembled. N‐doped nanoporous graphene with 50–150 nm pores and ≈99% porosity is found to exhibit a Pt‐comparable ORR performance, along with satisfactory durability in both neutral and alkaline media. Remarkably, the all‐solid‐state battery exhibits a peak power density of 72.1 mW cm−2; this value is higher than that of a battery using Pt/carbon cathodes (54.3 mW cm−2) owing to the enhanced catalytic activity induced by N‐doping and rapid air breathing in the 3D porous structure. Additionally, the all‐solid‐state battery demonstrates better performances than the aqueous‐type battery owing to slow corrosion of the Mg anode by solid electrolytes. This study sheds light on the design of free‐standing and catalytically active 3D nanoporous graphene that enhances the performance of both Mg–air batteries and various carbon‐neutral‐technologies using neutral electrolytes.
