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...

5 Al 0.5 Ge 1.5 (PO 4 ) 3 (LAGP) is an inorganic solid electrolyte with a Na superionic conductor (NASICON) structure that provides a channel for lithium ion transport. We coated LAGP particles on one side of a polypropylene (PP) separator film to improve the ionic conductivity of the separator, and waterdispersed polyvinylidene fluoride-hexafluoropropylene (PVDF-HFP) on the other side to reduce the interfacial resistance between the separator and the lithium metal anode. The results show that the LAGP/PP/PVDF-HFP separator has a high ionic conductivity (1.06 mS cm À1 ) at room temperature (PP separator: 0.70 mS cm À1 ), and an electrochemical window of 5.2 V (vs. Li + /Li). The capacity retention of a NCM|LAGP/PP/PVDF-HFP|graphite full cell is 81.0% after 300 charge-discharge cycles at 0.2C. When used in a NCM|LAGP/PP/PVDF-HFP|Li half-cell system, the initial discharge capacity is 172.5 mA h g À1 at 0.2C, and the capacity retention is 83.2% after 300 cycles. More significantly, the surface of the Li anode is smooth and flat after 200 cycles. The interface resistance increased from 7 to 109 U after 100 cycles at 0.2C. This indicates that the synergistic effect of the asymmetric coated LAGP and PVDF-HFP is beneficial to inhibiting the growth of lithium dendrites in the battery and reduces the interface resistance.

Summary The power battery as an indispensable part of electric vehicle has attracted much attention in recent years. Among these, the lithium‐ion battery is the most important option due to the high energy density, good stability, and low discharge rate. However, the thermal safety problem of lithium‐ion battery cannot be ignored. Therefore, it is very necessary to explore an effective thermal management system for battery module. Here, a thermal silica cooling plate‐aluminate thermal plate (SCP‐ATP) coupling with forced convection air cooling system as a thermal management system is proposed for improving the cooling performance of pouch battery module. The results reveal that the heat dissipating performance and temperature uniformity of pouch battery module with SCP‐ATP are greatly improved compared with other thermal management systems. Moreover, the highest temperature can be controlled below 50°C, and the temperature differences can be maintained with 3°C when the SCP‐ATP coupling forced convection is utilized to enhance the heat transfer coefficient. Furthermore, considering the cooling effectiveness and consumption cost comprehensively, the optimal air velocity of the SCP‐ATP coupling forced convection cooling system is 9 m/s. In addition, the SCP‐ATP filling with different proportions of acetone has also been investigated for pouch battery module, indicating that 50% acetone exhibited a better heat transfer effect than the 30% one. Therefore, this research would provide a significant value in the design and optimization of thermal management systems for battery module.
