“…The Al 2 O 3 -composite GPE also showed a better discharge capacity retention of ~96% (initial and final specific capacities of 166.3 and 160.2 mAh g −1 , respectively) ( Figure 11 f). Jain et al [ 101 ] presented efficient conduction pathways constructed in PVdF-based GPEs with Al 2 O 3 and boron nitride (BN) ceramic nano/microparticles. The high dielectric constants of Al 2 O 3 and BN facilitated anion capture in the GPE and the transfer of Li + without coordination to the anions.…”

Among the various types of polymer electrolytes, gel polymer electrolytes have been considered as promising electrolytes for high-performance lithium and non-lithium batteries. The introduction of inorganic fillers into the polymer-salt system of gel polymer electrolytes has emerged as an effective strategy to achieve high ionic conductivity and excellent interfacial contact with the electrode. In this review, the detailed roles of inorganic fillers in composite gel polymer electrolytes are presented based on their physical and electrochemical properties in lithium and non-lithium polymer batteries. First, we summarize the historical developments of gel polymer electrolytes. Then, a list of detailed fillers applied in gel polymer electrolytes is presented. Possible mechanisms of conductivity enhancement by the addition of inorganic fillers are discussed for each inorganic filler. Subsequently, inorganic filler/polymer composite electrolytes studied for use in various battery systems, including Li-, Na-, Mg-, and Zn-ion batteries, are discussed. Finally, the future perspectives and requirements of the current composite gel polymer electrolyte technologies are highlighted.

“…Many former researches have already proved that ceramic micro-or nano-materials (Al 2 O 3 [38,39], SiO 2 [40,41], ZnO [42], TiO 2 [43,44], etc) with low cost and easy operation were of particular significance in the battery applications, which are capable of promoting the electrolyte uptake capability, thermal and mechanical properties of separators. More interesting fact is that the introduction of ceramic particles into GPE as fillers can not only improve the dimensional stability of electrolyte membrane, but also enhance the absorption and maintenance of liquid electrolyte [38,45].…”

“…Hexagonal boron nitride (hBN) materials with outstanding thermal conductivity (up to 2000 W m −1 K −1 ) are considered to be promising fillers to improve the thermal conductivity of polymer separators and electrolytes. [ 15,16 ] Vishwakarma et al. presented a polyvinylidene fluoride (PVdF) gel polymer electrolytes with BN/Al 2 O 3 ceramic nano/microparticles.…”

“…presented a polyvinylidene fluoride (PVdF) gel polymer electrolytes with BN/Al 2 O 3 ceramic nano/microparticles. [ 16 ] The thermal conductivity of the electrolytes could be up to 1.2 W m −1 K −1 , which was 13 times higher than the inactivated PVdF membrane. However, the internal resistance of the electrolytes also increased since the volume fraction of the electrolyte mixture was reduced by the high loading of additions.…”

Proper distribution of thermally conductive nanomaterials in polymer batteries offers new opportunities to mitigate performance degradations associated with local hot spots and safety concerns in batteries. Herein, a direct ink writing (DIW) method is utilized to fabricate polyethylene oxide (PEO) composite polymers electrolytes (CPE) embedded with silane‐treated hexagonal boron nitride (S‐hBN) platelets and free of any volatile organic solvents. It is observed that the S‐hBN platelets are well aligned in the printed CPE during the DIW process. The in‐plane thermal conductivity of the printed CPE with the aligned S‐hBN platelets is 1.031 W −1 K−1, which is about 1.7 times that of the pristine CPE with the randomly dispersed S‐hBN platelets (0.612 W −1 K−1). Thermal imaging shows that the peak temperature (°C) of the printed electrolytes is 24.2% lower than that of the CPE without S‐hBN, and 10.6% lower than that of the CPE with the randomly dispersed S‐hBN, indicating a superior thermal transport property. Lithium‐ion half‐cells made with the printed CPE and LiFePO4 cathode displayed high specific discharge capacity of 146.0 mAh g−1 and stable Coulombic efficiency of 91% for 100 cycles at room temperature. This work facilitates the development of printable thermally‐conductive polymers for safer battery operations.
