RECYCLING METHOD OF ELECTRODE ACTIVE MATERIAL OF METAL OXIDE, ELECTRODE ACTIVE MATERIAL OF METAL OXIDE FOR LITHIUM SECONDARY BATTERY, ELECTRODE FOR LITHIUM SECONDARY BATTERY, AND LITHIUM SECONDARY BATTERY FABRICATED THEREBY |
摘要 |
The present invention relates to a recycling method of an electrode active material of a metal oxide for a lithium secondary battery. The method comprises: a first step for preparing electrode scrap containing an electrode active material of a metal oxide being generated in the process of manufacturing a lithium secondary battery; a second step for carbonizing a binder existing in the electrode scrap by thermally treating the electrode scrap in an atmosphere containing air or the mixed gas of air and nitrogen; and a third step for recovering the electrode active material of a metal oxide from the electrode scrap. According to the present invention, a user can minimize environmental pollution by using simple physical thermal treatment and a separation method and can recycle an electrode active material of a metal oxide contained in electrode scrap or a battery being generated in the process of manufacturing an electrode and a battery through a simple process with low costs. [Reference numerals] (S1) Preparing electrode scrap containing electrode active material of metal oxide;(S2) Heat-processing (300-700°C air atmosphere or air and nitrogen mixed gas atmosphere);(S3) Recovering electrode active material of metal oxide (grinding, sieving);(S4) Producing electrode for lithium secondary battery |
