Cathode active material and preparation method therefor |
| abstract |
The present invention relates to a cathode active material and a preparation method therefor and, specifically, to a cathode active material comprising: a core comprising natural graphite; and a shell encompassing the core and comprising a roughened amorphous carbon layer. According to the present invention, the cathode active material is roughened, and thus adhesive strength can be improved even while using a small amount of a binder because of the anchoring effect in which curved surfaces are caught between active materials coming in contact with each other. Therefore, the problem of an increase in resistance caused by the use of an excessive amount of a binder can be solved while implementing high loading of a cathode. In addition, high output of a battery can be implemented by facilitating the entering and exiting of lithium ions since the specific surface area increases due to a roughened surface. |
