dc.description.abstract | The surfaces of layer-structured Li[Li0.2Co0.1Mn0.7]O-2 nanodisks were nanocoated with polyaniline and examined by SEM and TEM studies, via the chemical oxidative polymerization of aniline in an acid medium for 10 min-Mn4+ ions in the pristine lithium manganese oxides acted as oxidants. During this reaction, the crystal structure of the pristine nanodisks was retained, and the XRD patterns showed no evidence of H+ exchange with the Li+ located between the manganese oxide layers. The nanocoated polyaniline was in the low molecular weight of base states, and the majority (similar to 70%) was complexed with Li[Li0.2Co0.1Mn0.7]O-2 nanodisks, as shown by UV-vis and FT-IR spectroscopic analysis. By application of nanocoated polyaniline nanodisks as the cathode material, the discharge capacity was improved by about 15%. Furthermore. the cyclability was enhanced with almost no change in discharge capacity being detected at extended cycle numbers, while that of pristine nanodisks showed a tendency to continually decrease as the number of cycles increased. Results from the present Study Suggest that a well-controlled polyaniline nanocoating, particularly formed with the aid of pristine metal oxides as oxidants for polymerization, call act as a potential buffer layer between electrodes and electrolytes, which makes this a promising method for the reducing/protection of Continuous Structural distortion that Occurs during extended charge-discharge cycling. | - |
