Ifilimu ye-Polyimide

Ifilimu ye-Polyimide: ifilimu yefilimu esebenza kakhulu esekelwe ku-polyimide, eyakhiwe yi-condensation nokukhishwa kwe-phthalic anhydride (PMDA) ne-diaminodiphenyl ether (DDE) ku-solvent ye-polar enamandla, elandelwa yi-imidization; Ingasetshenziswa njengento ehlukanisayo yamabhethri e-lithium, ekhonza ukuhlukanisa ama-electrode amahle namabi futhi ivimbele amasekhethi amafushane.
