The core components of a sodium-ion battery include a positive electrode, a negative electrode and an electrolyte. When charging, sodium ions are removed from the positive active material and embedded into the negative active material. During discharge, sodium ions are removed from the negative active material and embedded into the positive active material. The cathode MATERIAL of sodium ion battery is similar to that of LITHIUM battery in the preparation process of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC, and the active material is prepared first.
Then, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC active material for iron removal is mixed with adhesive to prepare the slurry, and then the slurry is coated on the diaphragm for drying. After drying, the positive electrode sheet of sodium ion battery can be wound and sliced to obtain. However, the traditional preparation method and device are not uniform when coating the slurry. Moreover, the active material in the slurry is easy to deposit during the coating process, resulting in poor positive discharge effect of the prepared sodium-ion battery.
In addition, hot air drying is used throughout the drying process. If the temperature of hot air drying is too low, the drying effect will be affected. If the drying temperature is too high or the drying time is too long, the coated paste will crack. As a result, the sodium ions prepared by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field are easily damaged during use.
