Remarkable heat-resistant halloysite nanotube/polyetherimide composite nanofiber membranes for high performance gel polymer electrolyte in lithium ion batteries

The high performance gel polymer electrolytes (GPEs) based on remarkable heat-resistant composite nanofiber membrane composed of polyetherimide (PEI) and halloysite nanotubes (HNTs) were obtained through the activation of stacked membranes immersed into liquid electrolyte. The crystallization behavior, microstructure and thermal stability of nanofiber membranes were analyzed. The HNT/PEI composite nanofiber membranes showed the sufficient...
