| titleOfInvention | Positive electrode active material and preparation method thereof, and sodium ion battery |
| abstract | The present application provides a positive electrode active material, a preparation method thereof, and an electrochemical energy storage device. The molecular formula of the positive active material is A x M[M'(CN) 6 ] y ·zH 2 O, wherein A is one or more of alkali metal ions and alkaline earth metal ions, and M and M' are transitional Metal, 0<x≤2, 0.8≤y<1, 0<z≤20. The content of M'(CN) 6 holes in the positive electrode active material is less than or equal to 0.2 mol/mol. Controlling the hole content of the positive active material within a certain range can improve the stability of the crystal framework structure of the positive active material, thereby improving the cycle performance of the sodium-ion battery, and on the other hand, it can also improve the alkali metal or alkaline earth in the positive active material. content of metal ions, thereby increasing the first charge capacity of sodium-ion batteries. In addition, the content of holes in the positive electrode active material is within a certain range, and the transport channel of sodium ions in the positive electrode active material will not be blocked due to the existence of holes, so the sodium ion battery can also have better performance. rate performance. |
