Abstract: The present invention relates to an electrode for the lithium iron phosphate battery and the manufacturing method thereof, and more particularly, to a coated electrode for the lithium iron phosphate with a smooth surface and without de-powder phenomenon and the manufacturing method thereof. The electrode provided in the present invention uses an arabic gum modified by adding silicone-based gel into the arabic gum. The lithium iron phosphate active material and the conductive agent in a certain ratio are added into the aforesaid modified arabic gums, after the mixing process, a liquid slurry with a certain viscosity is formed. Then, the liquid slurry is coated uniformly onto a positive current collector of aluminum foil or mesh, and followed by the process like drying, calendaring, cutting and etc. to form positive electrode plate. The electrode in the present invention has the characteristics of smooth surface and no de-powder phenomenon.

Abstract: 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.
