SURFACE PURIFICATION OF NATURAL GRAPHITE AND EFFECT OF IMPURITIES ON GRINDING AND PARTICLE SIZE DISTRIBUTION |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To develop a purification method of natural graphite which is equal to or exceeds electrochemical properties of graphite actually used as electrode material in a lithium-ion battery. <P>SOLUTION: The natural graphite is ground into a small grain size before purification and certain chemical purification is performed thereafter so that an extremely uniform electrode can be obtained. <P>COPYRIGHT: (C)2013,JPO&INPIT |
