摘要
This paper addresses a Fractal Theory based tipped needleless electrospinning technology. The electric field intensity distributions of the different fractal electrospinning spinnerets were simulated and analyzed using finite element analysis technology, and the distribution of the field intensity was optimized and improved thereof. Two layers of electrospun Si O_2 doped PI(Si O_2@PI) membranes prepared with fractal electrospinning technology was combined with a single layer of modified PE(m PE) membrane, forming a sandwich structured Si O-2@PI/m PE/Si O_2@PI nanofiber composite membrane, which could be used as lithium ion battery separator. The test results indicated that the sandwich like trilayered PI/PE/PI nanofiber composite separator could dramatically increase the thermal safety performance and impart the lithium ion battery with low temperature shutdown function and high temperature thermal stability, having slightly inferior mechanical strength and superior other relevant properties compared to the thrilayered separator of Celgard PP/PE/PP, resulting in potential applications in high end lithium ion batteries.
