“…[24,25] More remarkably, using environmentally insensitive zinc enables easier and cheaper fabrication and packaging of Zn-based batteries than those of lithium-based countparts. [8,26] The recent development of nanomaterials and nanotechnology have strongly propelled the emergence of Zn-based batteries with excellent rechargeability through optimizing structure, composite, and morphology of their components, etc. These batteries possess a similar configuration, which consists of a zinc anode, an aqueous alkaline electrolyte solution, and a cathode (i.e., MnO 2 , Ni(OH) 2 , air electrode).…”

“…[8,29,34] While, as compared to large volume of flexible Zn-based batteries literature that focused on cathode materials or electrolyte system, research papers that concentrated on the mechanism of zinc dendritic growth are surprisingly rare. This is considered to be another critical factor in developing Zn-based batteries with superior rechargeability that could be compared to that of conventional lithium-ion batteries.…”

“…[4] This performance roll-off is largely due to the fact that high barrier encapsulation of air and moisture sensitive lithium battery materials can severely impact the effective volumetric efficiency as the batteries are miniaturized. [6][7][8] The potential to yield high volumetric capacities by using less environmentally sensitive materials in the batteries sees zinc as an attractive anode alternative to lithium.

date, there have been commercial efforts to manufacture lithium thin film batteries (<1 mm in thickness) being flexible and suitable for use in card-type and wearable devices. [3] However, these thin and flexible lithium-ion batteries have typically exhibited far less volumetric energy densities (<200 Wh L −1 ) than those of conventional lithium-ion batteries (<650 Wh L −1 ). [4] This performance roll-off is largely due to the fact that high barrier encapsulation of air and moisture sensitive lithium battery materials can severely impact the effective volumetric efficiency as the batteries are miniaturized. Therefore, high volumetric energy density lithium batteries with thickness <1 mm will be critical to enabling flexible electronics. [5] To this end, notable advancements have been made in the design of flexible lithium-sulfur and lithium-air batteries-those cathode chemistries enable high theoretical energy densities of 2800 and 6940 Wh L −1 , respectively-yet there remains substantial room for improvement. [6][7][8] The potential to yield high volumetric capacities by using less environmentally sensitive materials in the batteries sees zinc as an attractive anode alternative to lithium. In addition to the stability, zinc is likely to experience less cost pressure on raw material availability compared to lithium. In all cases, zinc secondary batteries represent a highly promising area of technology for Flexible Zn-based batteries are regarded as promising alternatives to flexible lithium-ion batteries for wearable electronics owing to the natural advantages of zinc, such as environmental friendliness and low cost. In the past few years, flexible Zn-based batteries have been studied intensively and exciting achievements have been obtained in this field. However, the development of flexible Zn-based batteries is still at an early stage. The challenges of developing flexible lithium-ion batteries are presented here. Then, a brief overview of recent progress in flexible zinc secondary batteries from the perspective of advanced materials and some issues that remain to be addressed are discussed.

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.

The development of high‐efficiency Zn−air batteries represents one of the emerging energy storage and conversion technologies. In this work, hierarchically structured N, P co‐doped graphene (NPHG) has been synthesized through the chemical polymerization of aniline and phytic acid in the presence of SiO2 nanoparticles and applied as air cathodes for rechargeable Zn−air batteries, owing to its high bifunctional oxygen electrocatalytic activities. The P−N bond, rather than P−C or P=N bonds, in NPHG is proposed to be responsible for the high catalytic activity. The rechargeable Zn−air batteries assembled from this NPHG exhibited much higher reversibility and better stability as compared with a benchmark Pt/C catalyst.
