Method of synthesizing phosphate salt of high purity for preparation of electrode material |
| abstract |
The present invention provides a cost-effective method of synthesizing phosphate salt of a metal M such as Fe and Mn that can be used for electrode active material of a lithium secondary battery. An oxidization-precipitation reaction is carried out on metal such as Fe(II) and Mn(II) to produce phosphate salt and hydroxide of the metal oxidized e.g. Fe(III) and Mn(III). With overdosed phosphoric acid, hydroxide of the oxidized metal is then converted to a phosphate salt. The invention also provides a method of preparing “wet” phosphate salt nanoparticles and their application in the synthesis of a cathode material. The present invention exhibits numerous technical merits such as lower cost, easier operation, and being environmentally friendly. |
