PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC preparation process for cathode material of sodium ion battery, the process includes the following steps: First of all, the production line of cathode materials for sodium ion batteries is assembled, and then the sodium salt is mixed with manganese oxide, titanium oxide and nickel oxide in a mixing tank. After mixing, the sodium salt is added to the ball mill and anhydrous ethanol is added for ball grinding for 4h. After the ball grinding, it is screened and dried. The sodium salt is selected na2c4o4, and the specific drying temperature can be controlled at 80 ° C.
The main part of the PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC device mainly includes the base diaphragm discharge device, the positive coil winding device, the slurry feeding device, the slurry coating mechanism, the drying device, and the edge cutting device. The dried mixture is calcined at high temperature for 10h under the protection of inert gas.
Then cool to room temperature to obtain the active material; Argon gas can be used as the inert gas, and the temperature of high temperature calcination is controlled in the range of 680℃. After PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC, the slurry is evenly coated on the pulled diaphragm, and with the diaphragm into the drying device for hot air pre-drying, and then hot press roller hot press drying, and then through the cutting device to remove the scraps, and finally wind up.
