SURFACE-MODIFIED LOW SURFACE AREA GRAPHITE, PROCESSES FOR MAKING IT, AND APPLICATIONS OF THE SAME |
摘要 |
Surface-modified, low surface area synthetic graphite may have a BET surface from 1.0 to 4.0 m2/g and a crystallite size Lc to crystallite size La ratio of greater than 1. Processes for modifying the surface of low surface area synthetic graphite may result in surface-modified, low surface area synthetic graphite have a BET surface from 1.0 to 4.0 m2/g and a crystallite size Lc to crystallite size La ratio of greater than 1. Such synthetic graphite may have many uses, including for example, as a negative electrode material in lithium-ion batteries. |
