“…The Al–H 2 O 2 cell with CNF‐0.25 cathode exhibited superior peak power densities of 273 and 360 mW cm −2 at 20°C and 50°C, respectively, indicating that Co/Ni foam was a potential alternative cathode for H 2 O 2 reduction in alkaline fuel cells 43 .

[58][59][60][61][62] 3.2 | Mg-H 2 O 2 batteries Among the metal-air batteries, the Mg-air battery is considered a promising candidate for future energy storage and conversion systems owing to the high theoretical potential of 3.1 V and impressive theoretical energy density of 6.8 kWh kg −1 . 3 In fact, the Mg-air battery exhibits lower work potential and capacity, which is severely hampered by the output voltage loss and the limited anodic utilization efficiency of Mg due to selfcorrosion or side reactions.…”

The aqueous metal–H2O2 batteries have been paid rapidly increasing attention due to their large theoretical energy densities, attractive power density, and multiple applications (air, land, and sea), especially in low‐content oxygen or nonoxygen conditions in which metal–air cells are out of work. However, the requirements of metal–H2O2 batteries are different due to the order of metal activities (Mg > Al > Zn) as well as metal–air cells. Aqueous metal–H2O2 batteries mainly include Al–H2O2, Mg–H2O2, and Zn–H2O2 batteries with the respective scientific problems, including battery structures, single/dual‐electrolyte systems, electrocatalysts for O2 reduction/evolution reactions, H2O2 reduction/production/decomposition, and the designability of anode to inhibit self‐corrosion. In this review, we summarized battery architectures, possible mechanisms, and recent progress in metal–H2O2 batteries, including Al–H2O2, Mg–H2O2, and Zn–H2O2 batteries. Several perspectives are also provided for these research fields, which may be focused on in the future.

“…In the literature, this characteristic is obtained in Al-air battery tests. [37] The power density of the Al-smooth electrode reaches a maximum at a current density of about 7 mA cm À 2 , the power density of the Al-porous electrode reaches a maximum at about 14 mA cm À 2 , and then the power densities decrease as the current density increases. The maximum power densities obtained for the Al-smooth and Alporous electrode are 5.24 mWh cm À 2 and 7.42 mWh cm À 2 , respectively.…”

This study compared the electrochemical performances of porous surface electrodes obtained by the salt casting process against a smooth surface electrode. Potentiodynamic polarization test, linear sweep voltammetry (LSV), and electrochemical impedance spectroscopy (EIS) tests of porous and smooth Al electrodes were performed using 0.5 M NaOH solution. According to the Tafel analysis, the Jcor value of the Al‐porous electrode was measured as 3.23 mA cm−2, which is approximately 55 % higher than the Al‐smooth electrode. The Ecor value was more negative for the Al‐porous electrode. Results of the low charge transfer resistance (2.2 Ω) of the Al‐porous electrode compared to the Al‐smooth electrode (2.8 Ω) concluded that the porous surface was increased the current density by increasing charge transport due to higher surface area. The galvanostatic discharge tests of the electrodes were carried out in an Al‐air battery test cell using a graphite carbon air cathode. As a result, the power density of the Al‐porous electrode was approximately 42 % higher than the Al‐smooth surface electrode.

“…Electrospun CNFs with unique properties such as high porosity, flexibility, strength, and high specific surface area possess great advantages by having the space for a large number of active sites, shortening the diffusion pathways, and improving the reaction kinetics, which makes them promising for RZAB air electrode catalyst application [ 5 , 9 ]. Furthermore, this technique enables versatile introduction of different transition metals (TMs) and their compounds into CNFs, which have been confirmed to provide the active sites for ORR (e.g., TM-Nx) and OER (e.g., TM oxides) [ 8 , 9 , 13 , 14 ]. Despite the problems with uniform distribution of several TMs at once in one nanocarbon catalyst, multiple TM-containing materials have been proposed to be more efficient non-PGM bifunctional oxygen catalysts than single TM-based ones [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ].…”

The goal of achieving the large-scale production of zero-emission vehicles by 2035 will create high expectations for electric vehicle (EV) development and availability. Currently, a major problem is the lack of suitable batteries and battery materials in large quantities. The rechargeable zinc–air battery (RZAB) is a promising energy-storage technology for EVs due to the environmental friendliness and low production cost. Herein, iron, cobalt, and nickel phthalocyanine tri-doped electrospun carbon nanofibre-based (FeCoNi-CNF) catalyst material is presented as an affordable and promising alternative to Pt-group metal (PGM)-based catalyst. The FeCoNi-CNF-coated glassy carbon electrode showed an oxygen reduction reaction/oxygen evolution reaction reversibility of 0.89 V in 0.1 M KOH solution. In RZAB, the maximum discharge power density (Pmax) of 120 mW cm−2 was obtained with FeCoNi-CNF, which is 86% of the Pmax measured with the PGM-based catalyst. Furthermore, during the RZAB charge–discharge cycling, the FeCoNi-CNF air electrode was found to be superior to the commercial PGM electrocatalyst in terms of operational durability and at least two times higher total life-time.
