“…Moreover, the R SEI for the cell with CPS is stabilized after 50 cycles, indicating more stable and suppressed SEI layer formation, which facilitates Li + transport through the interfacial layer (code 3–16). Similar changes in impedance also appear in other cells with filler‐coated PE separators, including SiO 2 ‐, [ 90 ] Al 2 O 3 ‐, [ 112,128 ] ZrO 2 ‐, [ 75 ] ZSM‐, [ 86 ] and OAPS‐coated [ 71 ] separators, indicating improved electrolyte/electrode interfaces and stable and suppressed SEI layer formation due to the filler coatings. These results were ascribed to the fact that the surface coated fillers enhance hydrophilicity and affinity with the electrolyte, leading to improved electrolyte adsorption and ion conduction in the coated separators.…”

Recently, stringent requirements brought on by environmental regulations and safety issues are driving the development of solid electrolytes to replace conventional liquid electrolyte systems for lithium‐based secondary batteries (LiBs). However, the low Li‐ion conductivity and/or poor mechanical properties of electrolytes remain the main obstacles hindering their commercialization. Hierarchitectural and composite polymer separators (CPSs) based on electrolyte membranes have been reported as promising tools for both high ionic conductivity and mechanical stability. In light of such work, the new types of flexible electrolytes based on phase‐separated and mixed‐phase morphologies achieved via self‐assembly and the use of functional molecular composites are reviewed along with the fundamental mechanisms associated with such systems. In particular, the structure and morphology, ionic conductivity, thermal/mechanical stability, and fabrication of polymer electrolytes are introduced. Additionally, recent advancements in CPSs including methods of ensuring low interfacial resistance, the respective contributions of these critical factors to the significant functional properties of CPSs, and directions for development and essential applications in the field of CPSs for LiBs are presented. Based on previous works, the perspectives put forth will aid in the design of advanced electrolytes for practical Li secondary batteries in the near future.

“…However, this type of thermally unstable separator could suffer thermal shrinkage when the operating temperature exceeds the melting point, which would further lead to thermal runaway and safety issues of the battery (Song et al, 2019). Therefore, the separator of the battery should have a good porosity property but not affect the thermal stability and mechanical strength at a certain level (Moon et al, 2019). To satisfy these requirements, a cellulose-based separator was introduced for the aluminium-air battery (Pan et al, 2018;Pan et al, 2019b).…”

Global energy demand is rising due to the rapid development and adoption of new technologies in every sector. Hence, there is a need to introduce a clean energy source that does not cause damage to the environment. Aluminium-air battery with its high theoretical specific volumetric capacity is an exciting alternative for post-lithium energy storage and has been at the forefront of energy research for years. However, the conventional aqueous electrolyte-based aluminium-air battery with bulky liquid storage, parasitic corrosion of aluminium in contact with the electrolyte, and formation of a passive oxide or hydroxide layer has precluded its widespread application. In order to achieve successful simplification and cost-effectiveness, a novel idea of a polypropylene-based aluminium-air battery is proposed. In this work, a polypropylene-based aluminium-air battery was constructed using aluminium foil as an anode, carbon fiber cloth as an air-cathode, and Polypropylene and Kimwipes as the separator. The effects of the electrolyte concentration on the aluminium-air battery were investigated and analyzed using various discharge currents. The study showed that the performance of the polypropylene separator is better than that of the Kimwipes separator. The battery capacity is negatively correlated with the concentrations of the electrolyte. At a discharge current of 30 mA, the aluminium-air battery has a specific capacity of 375 mAh g−1 when 1 M of potassium hydroxide was used as electrolyte.
