[0027] Working principle: Ceramic diaphragm: A means to improve the thermal stability of high energy density batteries. A ceramic layer is made on the negative electrode and diaphragm of the battery to improve the safety performance of the battery. In the structure of lithium batteries, the diaphragm is one of the key internal components. The performance of the diaphragm determines the interface structure and internal resistance of the battery, which directly affects the capacity, cycle and safety performance of the battery. The slitting device mainly uses a slitting knife 4 to cut the ceramic diaphragm, which can be cut into suitable lengths. The top of the slitting table 10 is provided with a slitting groove. After the cylinder 3 is pressed, the slitting knife 4 is driven to move up and down. After the slitting knife 4 applies pressure to the slitting groove, the ceramic diaphragm can be slit. During the slitting process of the slitting knife 4 repeatedly moving with the slitting groove, cracks will appear on the inner surface of the slitting groove. Once the cracks are formed, they will gradually expand with the use time, and may eventually cause the slitting groove to rupture, thus affecting the quality of the slitting of the ceramic diaphragm. The slitting table 10 is located at the bottom of the slitting knife 4. The four straight blocks 13 are respectively sleeved with the corresponding screws 12. The four nuts 14 are used to tighten the screws 12 at one end. The slitting table 10 can be firmly limited on the top of the straight plate 7 by the sleeve. When the slitting groove is damaged, the four nuts 14 are rotated in the opposite direction, and then the slitting table 10 is pulled upward, and the four straight blocks 13 are gradually separated upward from one end of the four screw rods 12. Then, a new slitting table 10 can be replaced. The slitting table 10 can be disassembled and replaced through this structure, avoiding the occurrence of cracks in the slitting groove and affecting the slitting quality of the ceramic diaphragm. The noise reduction layer 18 is made of rock wool board, which can effectively absorb and isolate noise, reducing the impact of the slitting knife 4 on the ceramic The noise during the slitting of the ceramic diaphragm improves the usability of the slitting device. After the bottom surfaces of the four arc blocks 15 are respectively fitted with the surfaces of the two positioning plates 5, one end of the four limiting bolts 16 are embedded into the inside of the four recessed holes 6 in turn, and the two are threadedly connected, so that the positioning plate 5 and the straight plate 7 can be limited and fixed. The pressure-resistant layer 17 is made of titanium alloy material and has excellent pressure resistance and strength. The wear-resistant layer 19 is made of tungsten-cobalt alloy and has excellent wear resistance. The coordinated use of the two prolongs the service life of the slitting device.
