| titleOfInvention | Potassium ion battery, negative electrode active material and negative electrode thereof, and preparation method and application of negative electrode active material and negative electrode |
| abstract | The invention discloses a potassium ion battery, a negative electrode active material, a negative electrode, a preparation method and application thereof, and relates to the technical field of potassium ion batteries. The potassium ion battery negative active material comprises a bimetallic oxide or a composite material thereof, and the general formula of the composition of the bimetallic oxide is M Ⅰ1‑x M Ⅱx O(OH) x Wherein M is I Is a divalent metal, M Ⅱ Is a trivalent metal, x is in the range of 0<x<1. The invention takes the layered double metal oxide and the composite material thereof as the cathode active material, the double metal oxide has a rapid potassium ion transmission channel, the rapid embedding and de-embedding of potassium ions can be realized, the crystal structure is stable, the phase change does not occur in the embedding and de-embedding process of the potassium ions, the reaction mechanism is the intercalation and conversion reaction, and the potassium ion battery adopting the double metal oxide or the composite material thereof as the cathode active material has high specific capacity, good rate capability and long cycle life. |
