| 摘要 |
The present invention relates to a lithium ion cathode material lithium iron phosphate having oxygen vacancy and doped in the position of Fe and a preparation method of quick micro-wave sintering for the same. The molecular formula of the product in present invention is expressed as LiFe1-x-aMeaMxPO4-yNz, wherein Me is one or more elements selected from Mg, Mn or Nd, and M is one or more elements selected from Li, Na, K, Ag or Cu; 0≦̸x≦̸0.1, 0<a≦̸0.1, 0<y≦̸0.5, 0≦̸z≦̸0.5, wherein x and z can not be 0 simultaneously. The quick micro-wave sintering preparation method in the present invention has advantages of high production efficiency, low energy consumption, good batch stability of the prepared product, excellent rate performance and cycle performance. |
