PROCESS FOR REDUCING MAGNETIC AND/OR OXIDIC IMPURITIES IN LITHIUM-METAL-OXYGEN COMPOUNDS |
摘要 |
A method of reducing magnetic and/or oxidic contaminants in lithium metal oxygen compounds in particle form, in order to obtain purified lithium metal oxygen compounds, by means of treatment in a grinding process and sifting process with continuous or non-continuous removal and obtaining of the purified lithium metal oxygen compound. The grinding process and sifting process are terminated prematurely before the residue amounts to less than 1% of the quantity m. The residue, containing contaminants, is discarded. |
