Combining polymeric membranes with inorganic woven fabric: Towards the continuous and affordable fabrication of a multifunctional separator for lithium-ion battery

Analysis of Thermal–Mechanical Properties of Silicon Dioxide/Polyvinylidene Fluoride Reinforced Non-Woven Fabric (Polypropylene) Composites

“…After the test of high temperature heating in the previous step, we further carried out the flame combustion test. A similar phenomenon was found in the combustion test [18]. The combustion properties of different composites are shown in Figure 6.…”

Enhancement of the electrochemical performance of lithium-ion batteries by SiO2@poly(2-acrylamido-2-methylpropanesulfonic acid) nanosphere addition into a polypropylene membrane

“…Under high power output or high temperature, the separator of lithium batteries can exhibit severe thermal shrinkage, which leads to short circuiting of the cells with safety problems. [55][56][57][58] As presented in Fig. 6, the SiO 2 @PAMPS/PP-18% maintains complete dimensional stability at 165 C, and the thermal shrinkage is inferior to that of the pristine PP membrane at 185 C owing to the excellent heat resistance of the SiO 2 particles.…”

Aramid Nanofibers Reinforced Cellulose Paper-Based Lithium-Ion Battery Separator with Improved Safety and Cycling Stability

“…Furthermore, it was observed from DSC curves (Fig. 5(b)) that the endothermic peak of PP separator appeared at about 165°C, which could be assigned to the melting of PP and caused the shutdown of micropores (Xu et al 2019). In contrast, no obvious endothermic peak was recorded below 300°C for the CF-based separators, demonstrating the high stability in the pore structure of CF-based separators at high temperatures.…”

“…(decreased from 145.4 mA h g − 1 to 130.3 mA h g − 1 ), which was also higher than that of PP separator (82.8%). Additionally, the coulombic e ciency was found to be nearly 100% for the battery using CF/ANF-20 separator during 100 cycles, but was relatively low at rst cycle due to the generation of solid electrolyte interfacial (SEI) layer (Xu et al 2019). The severe capacity degradation and poor cycling performance of CF-based battery mainly arose from the non-homogeneous pores of the CF separator, through which a mass of lithium dendrites could be formed as a consequence of the undistributed deposition of Li + , therefore leading to the depletion of liquid electrolyte and formation of thick SEI layer (Lv et al 2021;Zhang et al 2015).…”
