“…[15][16][17] Exploring efficient and stable electrocatalysts for ORR/OER is crucial to overcome these issues. [18,19] Currently, there exist difficulties to find a favorable electrocatalyst to stimulate both reactions because elegant OER catalysts usually exhibit poor catalytic activity toward ORR and vice versa.The representative examples are single atoms catalysts (SACs) and layered double hydroxides (LDHs).

Representatively, the ORR/ OER delivers the discharge/charge process of both aqueous Zn-air batteries and aprotic Li-air batteries which are promising power source candidates for prevailing portable devices and electric vehicles. [7][8][9][10][11][12][13][14] However, the sluggish kinetics of molecular oxygen electrocatalytic reduction and evolution lead to high overpotentials, poor rate capability and short cycle life, severely hampering the widespread implementation of these systems. [15][16][17] Exploring efficient and stable electrocatalysts for ORR/OER is crucial to overcome these issues. [18,19] Currently, there exist difficulties to find a favorable electrocatalyst to stimulate both reactions because elegant OER catalysts usually exhibit poor catalytic activity toward ORR and vice versa.The representative examples are single atoms catalysts (SACs) and layered double hydroxides (LDHs). [20][21][22] There has been significant progress on SACs and LDHs with successfully exploration of various catalysts, such as MnNC, [23] Fe SAs/NC, [24] CoAl LDH, [25] and CoNiFe LDH, [26,27] etc.; however, SACs and LDHs exhibit dedicated catalytic activity toward ORR and OER, respectively. Take the noble metal catalysts for another example, Ru and Ir based materials are prominent OER catalysts while poor for ORR. Oppositely, Pt based materials are elegant toward ORR but poor for OER. Interface engineering is an efficient strategy to enhance the electrocatalytic activity of hybrid materials by taking advantage of the synergistic effect of double or even multiple active sites. Here, the rational design of a Pd/NiO atomic interface with well patterned Pd arrays imbedded into NiO thin films are reported to boost the catalytic activity toward the oxygen reduction/ evolution reaction. Theoretical analysis elucidates that the Pd (111)/NiO (111) interface with minimized lattice mismatch effectively adsorbs intermediates (OH * , LiO 2 * , Li 2 O 2 * , and Li 2 O * ) and induces the growth/decomposition of electrochemical reaction products, which greatly lowers the Gibbs energy barrier of crucial steps and boosts the reaction kinetics. As expected, such hybrid thin films exhibit high catalytic activity for both the oxygen reduction reaction and oxygen evolution reaction, with performance comparable to the benchmarked Pt/C and RuO 2 catalysts. Moreover, favorable performance is also achieved in both aqueous Zn-air batteries and aprotic Li-air batteries with an overpotential of only 0.69 and 0.50 V, respectively. This work suggests the great potential of such particularly morphological hybrid thin films in the development of high-performance catalysts for energy storage and conversion.

“…The free-standing and binder-free Co3O4@NiCo2O4/CC cathode displayed extraordinary ORR/OER activity and greater cycling stability, a specific capacity of 10645 mAh/g (Figure 9b), and stability of 225 cycles without obvious degradation were achieved. [119] With the same vision, in Li-O2 batteries, metal/metal oxide composite catalyst (Fe2O3@C@MnO2) which combine Fe2O3 and MnO2 displayed enhanced cycling performance and reduced charge voltage than single C and Fe2O3@C electrodes. [120] Zhang and et al designed and synthesized the metal hybrid catalyst Mn-MOF-74@CNTs as a cathode material for Li-O2 batteries where Mn-MOF-74 nanoparticles were grown directly on carbon nanotubes using additive-mediated synthesis method.…”

The cutting-edge photovoltaic cells are an indispensable part of the ongoing progress of earth-friendly plans for daily life energy consumption. However, the continuous electrical demand that extends to the night time requires a prior deployment of efficient real-time storage systems. In this regard, metal-air batteries have presented themselves as the most suitable candidates for solar energy storage, combining extra lightweight with higher power outputs and promises of longer life cycles. Scientific research over non-precious functional catalysts has always been the milestone and still contributing significantly to exploring new advanced materials and moderating the cost of both complementary technologies. Metal-organic frameworks (MOFs) derived functional materials have found their way to the application as storage and conversion materials, owing to their structural variety, porous advantages, as well as the tunability and high reactivity. In this review, we provide a detailed overview of the latest progress of MOF-based materials operating in metal-air batteries and photovoltaic cells.

volume and improving its energy density. [39-47] Under the proposition of guaranteeing electrochemical performance, the components in the flexible metal-air battery, including active cathodes, metal anodes, separators, current collectors, and packaging materials, should be flexible to endure frequent mechanical strain. [48-54] Moreover, the safety of flexible battery is paramount during repeated deformation conditions. [55-60] Up to now, there are many flexible metal-air batteries have been proposed, such as flexible lithium (Li)-air battery, flexible Li-CO 2 battery, flexible zinc-air battery, flexible aluminum-air battery, silicon-oxygen battery, and so on. [61-71] Among various metalair batteries, Li-air batteries have raised much concern and got rapid development as a result of their theoretical energy density up to 5928 Wh kg −1 , eco-friendly, good reversibility, and high operating voltage of 2.96 V. [24,25,72-74] Here, we review the latest advances of flexible Li-air battery, focusing on the fabrication of flexible cathodes for improving the electrochemical performance, development of electrolyte for obtaining long durability, design of battery structure for achieving high flexibility. It should be noted that some reported studies on Li-air batteries were tested in the oxygen atmosphere rather than the ambient air, which is described as "Li-O 2 batteries." [27,75] 2. Flexible Cathodes The typical Li-air battery commonly made of Li metal anode, air cathode and aprotic electrolyte, which worked through the reaction of 2Li + O 2 → Li 2 O 2 (E OCV = 2.96 V). [76-80] As mentioned above, all components in flexible Li-air batteries should be flexible to accommodate stresses and strains in deformation. [10] However, the cathode and current collector are typically rigid carbon paper or porous metal, which hardly meet the needs of flexible Li-air battery, seriously restricting the development of the battery flexibility. [81-83] Moreover, the cathode should possess high catalytic activity to facilitate the OER and ORR reactions of Li-air battery, and porous structure to store the discharge products. [84-88] Therefore, it is urgently required to develop flexible and high-performance cathode materials with high mechanical stability for flexible Li-air batteries. Different from carbon paper with a rigid structure, carbon cloth is flexible that woven from multistrands of carbon fiber. Because of its mechanical flexibility and conductivity, carbon cloth was widely used as a flexible substrate material for the cathode in Li-air battery. [89-92] Liu et al. first proposed a flexible Li-O 2 battery with a flexible and recoverable cathode that constructed on the carbon cloth by depositing densely TiO 2 Along with the popularity of flexible electronic products, the requirements for flexible energy storage devices are also increasing, including high energy density, long-term stability, and high-grade safety. Among various flexible energy storage devices, flexible lithium-air batteries are expected to be one of the best candidate...
