The Modification and Characterization of Mesophase Carbon Microspheres
Abstract: Mesophase carbon microspheres having a high charge-discharge efficiency, long life and other properties of the material, but its large current performance to be improved. Therefore, improving the performance of the intermediate phase structure, improve performance and power performance of its capacity to further expand its field of application for the positive significance. In this study, mesophase carbon graphite heat acidified its expanding treatment, research experimental conditions affect the performance of its structure in order to expect a high-performance carbon mesophase microspheres. The experimental determination of its acidification before and after puffing density, mixed acid and found that the ratio of the sample, high moisture content before puffing and puffing temperature greater impact on its structure.
