Publication/Patent Number: TW201927541A | Publication Date: 2019-07-16 | Application Number: 106143925 | Filing Date: 2017-12-14 | Inventor： Chen, Yi-lin Yang, Chun-chen Wu, Yi-shiuan Wu, Zong-han Wei, Chao-nan Lue, Shing-jiang Jessie Luo sin ping | Assignee: MING CHI UNIVERSITY OF TECHNOLOGY | IPC: B32B5/24 | Abstract: A composite separator comprises a nanofiber layer and two layers of porous polymer electrolyte membrane layers. The nanofiber layer comprises a plurality of organic nanofibers and a plurality of nanoparticles distributed in the organic nanofibers. The nanoparticles are the inorganic oxide nanoparticles functionalized by the nitrogen family quarternary onium salt. The two porous polymer electrolyte membrane layers are respectively formed on two opposite sides of the nanofiber layer. The porous polymer electrolyte membrane layer contains a vinylidene fluoride-hexafluoropropylene copolymer. The present invention also provides a manufacturing method of composite separator. The lithium ion battery made of the composite separator has a better discharge mAh/g and charging/discharging stability in high-power and high-temperature environment, which is advantageous to be applied in the power storage and power supply equipment in the high-power and high-temperature operation environment. | ||
