The precursors and cathode materials prepared by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC were observed. The pores in the precursors prepared by this method were evenly distributed. It can be seen that the residual amount of sodium on the surface of the anode material prepared by the method is significantly reduced compared with the corresponding proportion. The particle size of the prepared hydroxide precursor ranges from 3μm-18μm, the specific surface area is 8m2/g-30m2/g, the vibrational density is 1.2g/cm, 3-2.5g/cm3, and the internal pore size is 20nm-200nm.
The positive electrode MATERIAL prepared by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field is evenly mixed with conductive carbon black and polyvinylidene fluoride according to the mass ratio of 90:5:5, and then placed in a high-speed agitator grinding tool, after adding an appropriate amount of N-methylpyrrolidone, The slurry with appropriate viscosity was obtained by stirring at a speed of 3000rpm for 10min, and was coated on a clean fluid collector and placed in a vacuum drying oven for 24h.
After the positive electrode MATERIAL, which is dried well and PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic removal, is rolled to a suitable thickness, the electrode sheet with a diameter of 10mm is washed, and the battery shell is dried in a vacuum environment for 12h with the diaphragm. Finally, the 2025 button battery is assembled in the glove box with sodium sheet as the counter electrode. Blue electric ct2001a electrochemical tester was used for charge and discharge test. The voltage range was 2.5-4.2v, the current density was 0.2c, and the number of cycles was 50.
