| titleOfInvention | A kind of preparation method of positive electrode for lithium iron phosphate secondary battery and lithium ion battery |
| abstract | A method for preparing a positive electrode for a lithium iron phosphate secondary battery and a lithium ion battery belong to the technical field of lithium ion batteries. The purpose of the present invention is to solve the problem of unsatisfactory rate performance and low temperature performance of the existing lithium iron phosphate battery, the method is as follows: open the stirring tank, add conductive agent, lithium iron phosphate, positive electrode according to the mass ratio of the formula design Adhesive and NMP, stir and disperse evenly at the revolution speed of 20~60rpm, the speed of the dispersing disc is 200~2000rpm, adjust the revolution speed to 10~30rpm, take the material to measure the solid content, turn on the vacuum pump, and keep the vacuum degree ‑0.08~‑0.09MPa After stirring for 30 minutes, the vacuum was released to obtain a positive electrode slurry, and the obtained positive electrode slurry was coated on the positive electrode current collector to obtain a positive electrode. The positive electrode prepared by the invention has good adhesion and high ionic conductivity, and can realize high-rate rapid charge and discharge of lithium ion batteries. |
