To improve distribution of SiO2 nanoparticles for the incompatible PPS/SiO2 mixture, prerequisite for the efficient porous architecture, interface modulation by plasma-assisted mechanochemical (MP) treatment has been performed, and the MP-treated PPS/SiO2 composite exhibited perfectly homogeneous distribution of SiO2 nanoparticles, finally resulting in porous PPS membrane including a large number of pores with nearly monodisperse pore diameter after removal of SiO2 phase. Alongside the well-developed porous architecture, the porous PPS membrane also deployed notably improved wetting to electrolyte imparted by the MP-based interface modulation, which gave rise to the complete suppression of disastrous build-up and intrusion of lithium dendrite on a separator as well as the electrochemical performances superior to those of the existing PP separator such as the highly sustainable cyclic charging/discharging behavior. Furthermore, it was notable that the PPS membrane exhibited outstanding mechanical stability especially at high temperature even after a large number of pores were developed inside, which has been generic from the nature of PPS. Conclusively, it could be stated that the porous PPS separator is a promising candidate fulfilling the performance requirements for the high-performance LIB. ？ 2021 The Authors English Elsevier Ltd Highly sustainable polyphenylene sulfide membrane of tailored porous architecture for high-performance lithium-ion battery applications Article 10.1016/j.mtadv.2021.100186 1 Materials Today Advances, v.12 Materials Today Advances 12 scie scopus 000724694500001 2-s2.0-85119285883 Materials Science, Multidisciplinary Materials Science Article Lithium-ion battery Mecahnochemical treatment Polyphenylene sulfide membrane Porogen Porous separator
