“…Substances and Reagents: The chemicals employed in the work were IrO 2 (99.9%), 20 wt% Pt/C (denoted as 20Pt/C), SrCO 3 Synthesis of Pt-SCFP/C Composites: First, SCFP powder was mixed with Super P Li at a weight ratio of 2:8 using ball milling, which led to 20SCFP/C mixture. Then, 20Pt/C and 20SCFP/C were placed on the ball milling jar at certain weight ratios (2:1, 1:1, 1:2, and 1:4) using the same procedure to obtain Pt-SCFP/C composites.…”

“…Zinc (Zn)-air battery represents one of the most attractive metal-air battery technologies given its non-flammability and high energy density. [3] Large-scale application of Znair battery however has been limited by the sluggish kinetics of oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) in its air electrode. [2] The interest to use Zn as an anode component also comes from the fact that Zn has a relatively high redox potential of −0.763 V versus standard hydrogen electrode, enabling its operation in an aqueous electrolyte; reversible Zn plating/stripping can be achieved in a near-neutral or slightly acidic electrolyte (pH of 3.6-6.0) condition, which enables long cycle life; and two electrons are involved in the Zn electrochemical reaction, which leads to its high volumetric energy density.…”

Constructing highly active electrocatalysts with superior stability at low cost is a must, and vital for the large‐scale application of rechargeable Zn–air batteries. Herein, a series of bifunctional composites with excellent electrochemical activity and durability based on platinum with the perovskite Sr(Co0.8Fe0.2)0.95P0.05O3−δ (SCFP) are synthesized via a facile but effective strategy. The optimal sample Pt‐SCFP/C‐12 exhibits outstanding bifunctional activity for the oxygen reduction reaction and oxygen evolution reaction with a potential difference of 0.73 V. Remarkably, the Zn–air battery based on this catalyst shows an initial discharge and charge potential of 1.25 and 2.02 V at 5 mA cm−2, accompanied by an excellent cycling stability. X‐ray photoelectron spectroscopy, X‐ray absorption near‐edge structure, and extended X‐ray absorption fine structure experiments demonstrate that the superior performance is due to the strong electronic interaction between Pt and SCFP that arises as a result of the rapid electron transfer via the PtOCo bonds as well as the higher concentration of surface oxygen vacancies. Meanwhile, the spillover effect between Pt and SCFP also can increase more active sites via lowering energy barrier and change the rate‐determining step on the catalysts surface. Undoubtedly, this work provides an efficient approach for developing low‐cost and highly active catalysts for wider application of electrochemical energy devices.

Hydrogels are widely used in flexible aqueous batteries due to their liquid-like ion transportation abilities and solid-like mechanical properties. Their potential applications in flexible and wearable electronics introduce a fundamental challenge: how to lower the freezing point of hydrogels to preserve these merits without sacrificing hydrogels' basic advantages in low cost and high safety. Moreover, zinc as an ideal anode in aqueous batteries suffers from low reversibility because of the formation of insulative byproducts, which is mainly caused by hydrogen evolution via extensive hydration of zinc ions. This, in principle, requires the suppression of hydration, which induces an undesirable increase in the freezing point of hydrogels. Here, it is demonstrated that cooperatively hydrated cations, zinc and lithium ions in hydrogels, are very effective in addressing the above challenges. This simple but unique hydrogel not only enables a 98% capacity retention upon cooling down to −20 °C from room temperature but also allows a near 100% capacity retention with >99.5% Coulombic efficiency over 500 cycles at −20 °C. In addition, the strengthened mechanical properties of the hydrogel under subzero temperatures result in excellent durability under various harsh deformations after the freezing process.

“…Recently, aqueous zinc‐ion batteries (ZIBs) have been attracting tremendous interest as the most favorable candidate, since the Zn anode possesses low redox potential, high theoretical capacity, and excellent stability in water . Additionally, divalent zinc ions transfer two electrons, allowing ZIBs to achieve high capacity and an acceptable energy density.…”

Li‐ion batteries (LIBs) with excellent cycling stability and high‐energy densities have already occupied the commercial rechargeable battery market. Unfortunately, the high cost and intrinsic insecurity induced by organic electrolyte severely hinder their applications in large‐scale energy storage. In contrast, aqueous Zn‐ion batteries (ZIBs) are being developed as an ideal candidate because of their cheapness and high security. Benefiting from high operating voltage and acceptable specific capacity, recently, manganese‐based oxides with different various crystal structures have been extensively studied as cathode materials for aqueous ZIBs. This review presents research progress of manganese‐based cathodes in aqueous ZIBs, including various manganese‐based oxides and their zinc storage mechanisms. In addition, we also discuss some optimization strategies that aim at improving the electrochemical performance of manganese‐based cathodes, and the design of flexible aqueous ZIBs based on manganese‐based cathodes (MZIBs). Finally, this review summarizes some valuable research directions, which will promote the further development of aqueous MZIBs.
