PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC The method of removing iron graphite as a conductive agent for lithium ion battery positive slurry is carried out in the following steps: (1) First of all, the required amount of 70% to 90% of the solvent into the mixer, and then add the required amount of binder, mix 1 to 5 hours; (2) After the adhesive is completely dispersed, add the required amount of conductive agent graphite and mix for 0.5~2 hours; (3) After the conductive agent is completely dispersed, add the required amount of active material and mix for 2 to 6 hours.
After all components are completely dispersed, the residual solvent is added to adjust the viscosity of the slurry for removing iron from PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field to 4000~7000Mpa · S. The mixing equipment is a double planetary vacuum mixing machine, and the slurry temperature is controlled by the method of circulating water at the corresponding temperature into the planetary mixing bucket.
The beneficial effect of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC method is to provide a reasonable and reliable formula and preparation method for the actual use of graphite conductive agent in the cathode material of ion batteries. The use of graphite conductive agent can significantly reduce the internal resistance of batteries. Improve the battery performance of high current discharge, low temperature performance, high current charge-discharge cycle performance.
