| titleOfInvention | Lithium ion battery positive electrode slurry and positive electrode sheet and preparation method thereof, and lithium ion battery |
| abstract | The invention relates to the field of lithium ion batteries, and discloses a positive electrode slurry for a lithium ion battery, which contains a positive electrode active material, a polymerizable monomer having a polymerizable group and an initiator; the positive electrode active material is LiMn 1-m M m PO 4 or LiMn 1-m M m PO 4 and carbon complex, wherein, 0≤m<1, M is selected from Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Al, Mg and Ga At least one of; the polymerizable monomer is a siloxane monomer and/or a silazane monomer. Also disclosed are a lithium ion battery positive electrode sheet and a preparation method thereof, and a lithium ion battery. Through the above technical solution, the above slurry is coated on the conductive substrate. During the drying process, the polymerizable monomer can polymerize on the surface of the positive electrode active material particles to form a polymer layer, which effectively prevents the electrolyte from affecting the positive electrode active material. Erosion, preventing the dissolution of manganese. The lithium ion battery provided by the invention also has excellent cycle performance, high safety and high battery life. |
