Highly aligned polyimide/graphene oxide (PI/GO) nanofibers fabricated by electrospinning exhibit excellent thermal stability and electrochemical performance as separators for Li-ion batteries, with improved mechanical strength and resistance to Li dendrites.
Highly aligned polyimide/graphene oxide (PI/GO) nanofibers were fabricated by using the electrospinning method. As a separator for Li-ion batteries, the PI/GO nanofibers show excellent thermal stability, good wettability toward organic liquid electrolytes and superior electrochemical performance compared to raw PI and commercial battery separators. The GO nanosheets not only greatly enhance the mechanical strength of the PI matrix, but also increase the resistance to Li dendrites.
