“…This property makes them flame retardant, which is applicable for coating of the polyolefin separator. Both Al(OH) 3 (Figure C) and Mg(OH) 2 were investigated as the coating agent for PE separators . It was found that these metal hydroxides not only enhanced the thermal stability of the PE separator, but also improved the wettability of the separator.…”

Li-ion and Li-S batteries find enormous applications in different fields, such as electric vehicles and portable electronics. A separator is an indispensable part of the battery design, which functions as a physical barrier for the electrode as well as an electrolyte reservoir for ionic transport. The properties of the separators directly influence the performance of the batteries. Traditional polyolefin separators showed low thermal stability, poor wettability toward the electrolyte, and inadequate barrier properties to polysulfides. To improve the performance and durability of Li-ion and Li-S batteries, development of advanced separators is required. In this review, we summarize recent progress on the fabrication and application of novel separators, including the functionalized polyolefin separator, polymeric separator, and ceramic separator, for Li-ion and Li-S batteries. The characteristics, advantages, and limitations of these separators are discussed. A brief outlook for the future directions of the research in the separators is also provided.

“…While used in composite separators, they also enhance the thermal stability of separators. Yeon et al used aluminum hydroxide (Al(OH) 3 ) and magnesium hydroxide (Mg(OH) 2 ) metal hydroxides with PVDF‐HFP binder as a coating layer for PE separators. PE modified separators with both metal hydroxides show a reduction in self‐extinguishing time due to the respective fire‐retardant capabilities and also exhibit high dimensional stability at elevated temperatures, as given in Figure a,b.…”

metric tons of carbon dioxide (CO 2 ) and other pollutants per year, which accelerate global warming and major climate changes. [2] In order to mitigate these serious issues caused by fossil fuels and to compete with the energy generating devices based on fossil fuels, renewable energy sources like solar energy, wind energy, bioenergy, and geothermal energy are potential alternative power resources. However, these renewable energy resources need highly efficient energy storage devices for integrating and well distribution of energy. Rechargeable battery technology with high energy, high power density, long life cycle capability, fast cycling rate, and reasonable cost is the possible solution to store energy obtained from these renewable sources. [3] Among many rechargeable energy storage devices, lithium-ion batteries (LIBs) are the promising energy sources for integrating renewable resources and high power applications, owing to high energy density, lightweight, high flexibility, slow self-discharge rate, high rate charging capability, long battery life, and environmental benignity. [4,5] The aforementioned attractive properties of rechargeable LIBs promote its utilization in the wide range of applications like laptops, cell phones, electric vehicle, hybrid electric vehicles, renewable power stations, stationary electric power, defense arsenal, subsurface exploration, thermal reactors, and space vehicles. [6][7][8][9] From the last 30 years, rapid development has been observed in LIBs technology. Presently, LIBs hold twofold energy density as compared to the first commercial LIBs developed by Sony in 1991, but still, there are some challenges associated with LIBs that need to be solved for achieving high power density and efficient performances at high and low temperatures. Safety, cost, and enhancement in energy and power densities are the major concerns in next generation LIBs. [10][11][12] Separator is one of the important components of LIBs that is not directly involved in the electrochemical reaction, however, its properties, structure, and composition greatly influence the performance of batteries with respect to internal resistance, long cycle performances, high capacity, and safety. [13] The basic functions of the separator are to prevent the contact between anode and cathode to avoid internal short circuits, store liquid electrolyte, and permit the migration of ions during the chargedischarge process. [14][15][16] The ideal separator should possess Lithium-ion batteries (LIBs) are promising energy storage devices for integrating renewable resources and high power applications, owing to their high energy density, light weight, high flexibility, slow self-discharge rate, high rate charging capability, and long battery life. LIBs work efficiently at ambient temperatures, however, at high-temperatures, they cause serious issues due to the thermal fluctuation inside batteries during operation. The separator is a key component of batteries and is crucial for the sustainability of LIBs at high-temperatures. Th...

“…Since the separators in LIBs must have good affinities toward organic liquid electrolytes, their water contact angles [18,19] and electrolyte uptake amount [13,14,16] were also measured. The contact angles of the separators are nearly identical (~120 ) owing to the same raw materials and production conditions.…”
