Abstract
Polyethylene terephthalate (PET)–Al2O3 ceramic composited separator is prepared with organic adhesives PDA, inorganic adhesives, silane-coupling agent, and colloidal silica. The obtained separator is characterized in different ways. Morphology characterization by SEM shows that porous separator is obtained, and Al2O3 is evenly distributed on it. The Gurley number of the separator is 8 s/100 cc. Thermal behavior investigation and linear sweep voltammetry test show that the prepared separator has an outstanding thermal performance and electrochemical stability. Half-cell assembled with the composited separator reveals an outstanding cycle performance and a good rate performance. Therefore, the separator may be a suitable and excellent candidate for application in power battery, especially the one with higher safety.
