Popis:	100 Nano-composite polymer electrolytes were prepared by mixing various amounts of poly(acrylonitrile) (PAN), ethylene carbonate, and α-Al2O3 nano-particles. Batteries using these nano-composite polymer electrolytes were assembled with lithium iron phosphate and lithium metal as electrodes. Both electrolyte and the battery were characterized by powdered x-ray diffraction, differential scanning calorimetry, thermogravimetry, cyclic voltammetry, AC impedance analysis and battery charger/ discharger. Adding α-Al2O3 nano-particles in polymer electrolytes can effectively increase the conductivity of lithium ion, reduce the crystalline phase of PAN, and the interface resistances between the electrolyte and the electrodes. The electrolyte becomes solid as more PAN is added. This can improve the safety and the charge capacity of the battery.
