Synthesis of PVDF-SiO₂ nanofiber membrane using electrospinning multi-jet vertical on conveyor collector as a lithium-ion battery separator

Abstract Research on synthesis of PVDF-SiO 2 nanofiber membrane by electrospinning multi-jet vertical method conveyor collector as a lithium-ion battery separator was systematically investigated. Various voltages 15 kV, 16 and 17 kV types PVDF such Aldrich, Solvay, both mixtures were used for synthesis. The synthesized 4 hours with distance between the tip needle, 10 cm, flow rate 2.6 mL/hour speed 37 rpm. Furthermore, results tested physicochemical properties nanofiber. Solution B (PVDF Solvay) treated 17kV has largest porosity percentage value membrane, which 84.659%. optimum shrinkage ratio test from solution A Aldrich) voltages. smallest average diameter obtained voltage 15kV. FTIR spectrum not affected variations. In addition, assembled in using mixed types. then electrochemical battery. (Solvay) charge-discharge showing specific charge 107.472 mAh/g discharge 77.990 mAh/g.
