Positive active material for rechargeable lithium battery and method of preparing same |
| 摘要 |
Disclosed is a method of preparing a positive active material for a rechargeable lithium battery. In this method, a lithium salt is reflux-reacted with a metal salt in a basic solution. The resulting positive active material is a compound represented by formulas 1 to 14. The positive active material has a spherical or spherical-like form, a diameter of 10 nm to 10 mum, and a surface area of 0.1 to 5 m2/g. <table-cwu id="TABLE-US-00001"> <number>1</number> <table frame="none" colsep="0" rowsep="0"> <tgroup align="left" colsep="0" rowsep="0" cols="3"> <colspec colname="OFFSET" colwidth="42PT" align="left"/> <colspec colname="1" colwidth="112PT" align="left"/> <colspec colname="2" colwidth="63PT" align="left"/> <thead> <row> <entry></entry> <entry></entry> </row> <row> <entry></entry> <entry namest="OFFSET" nameend="2" align="center" rowsep="1"></entry> </row> </thead> <tbody valign="top"> <row> <entry></entry> <entry>LixMnA2</entry> <entry> (1)</entry> </row> <row> <entry></entry> <entry>LixMnO2-zAz</entry> <entry> (2)</entry> </row> <row> <entry></entry> <entry>LixM1-yM'yA2</entry> <entry> (3)</entry> </row> <row> <entry></entry> <entry>LixMn1-yM'yO2-zAz</entry> <entry> (4)</entry> </row> <row> <entry></entry> <entry>LixMn2O4</entry> <entry> (5)</entry> </row> <row> <entry></entry> <entry>LixMn2O4-zAz</entry> <entry> (6)</entry> </row> <row> <entry></entry> <entry>LixMn2-yM'yA4</entry> <entry> (7)</entry> </row> <row> <entry></entry> <entry>LixBA2</entry> <entry> (8)</entry> </row> <row> <entry></entry> <entry>LixBO2-zAZ</entry> <entry> (9)</entry> </row> <row> <entry></entry> <entry>LixB1-yM''yA2</entry> <entry>(10)</entry> </row> <row> <entry></entry> <entry>LixNi1-yCoyA2</entry> <entry>(11)</entry> </row> <row> <entry></entry> <entry>LixNi1-yCoyO2-zAz</entry> <entry>(12)</entry> </row> <row> <entry></entry> <entry>LixNi1&
