Electrospun LATP /PAN composite fiber-based membrane for lithium-ion battery separators

摘要

The lithium aluminum titanium phosphate (LATP)/Polyacrylonitrile (PAN) composite fiber-based membrane were prepared by electrospinning composite solution of LATP and PAN in N, N-dimethylformamide(DMF). The crystallization phase of the LATP particles were characterized by X-ray diffraction(XRD). The electrolyte uptakes of the electrospun LATP/PAN composite fiber-based membranes were also evaluated. In addition, the electrochemical performance of the liquid electrolyte-soaked electrospun LATP/PAN composite fiber-based is also improved after the introduction of LATP particles.
