The preparation methods of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC of layered oxide cathode materials for sodium ion batteries include sol-gel method, one-step solid-phase synthesis method, coprecipitation-high temperature solid-phase sintering method, etc. When the dried electrode sheet is pulled between the bottom roll and the circular cutter, the circular cutter can cut off the scraps, and then the resulting positive electrode sheet of the sodium ion battery is wound onto the roll.
The edge MATERIAL cutting device comprises a rotating seat symmetrically arranged at both ends of the upper surface of the PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC base, a bottom roller is arranged between the lower ends of the two rotating seats, a rotating rod is arranged above the bottom roller, and a circular cutter is arranged at both ends of the rotating rod. A cutting motor is arranged on the outer side of one of the rotating seats, and the output shaft of the cutting motor is connected with the end of the rotating rod.
Sol-gel method in the preparation of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC technology large-scale preparation of the operation, preparation conditions are not harsh, the cost is not expensive, but also can meet the needs of large-scale industrial production; At the same time, a first hot air hole is provided on the front and rear surfaces of the drying box located at the position of the hot air pipe, and a second hot air hole is provided on the upper surface of the drying box located directly above the hot press roll.
