چکیده انگلیسی
A novel method improving the performance of spinel LiMn2O4 at high temperature is studied. The copolymer was put into the interspaces of the LiMn2O4 electrode layer prepared by maleic anhydride and acrylamide for decorating LiMn2O4, involving groups to compound with the manganese-ion. It is found that with the act of modification of the functional copolymer, the 45th discharge capacity was improved at 55 °C from 56.8 to 81.4 mAh gâ1 on the LiMn2O4 electrode. Fourier transformed infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), scanning electron micrographs (SEM), inductively coupled plasma atomic emission spectrometry (ICP-AES) and a series of electrochemical measurements have been conducted in this work, and the effects of modification of the polymer layer are discussed.
