Diaphragm is one of the important inner members in the structure of lithium battery. The characteristics of the diaphragm determine the page structure and internal resistance of the rechargeable battery. It immediately endangers the capacity, circulation system and safety factor of the rechargeable battery.
Coated in the lithium battery pole piece, it can prevent the burrs generated during the slitting process of the positive electrode material from piercing the diaphragm, improve the safety performance of the lithium battery, improve the battery production process, and increase the energy density.
Compared with other batteries, lithium-ion batteries (LIBs) have the characteristics of high energy density, high power density, and light weight , . Therefore, LIBs are the most popular batteries and gradually become the first choice for automotive power sources , .
The transfer of lithium-ion batteries in rechargeable batteries is constrained by the characteristics of the raw materials themselves and the porosity characteristics after demulsification, which is mainly manifested in the technical parameters, that is, the positive ion oxidation-reduction potential.
The parameters of commonly used single power batteries are shown in Table 1 . Compared with other batteries, lithium-ion batteries (LIBs) have the characteristics of high energy density, high power density, and light weight , .
Boehmite + magnetic material has a low water absorption rate, which can effectively ensure the safety of the diaphragm. The specific gravity of boehmite is low, and the dosage can be reduced by 25% under the same coating area; the hardness is low, the service life of the coating roller is prolonged by 3-4 times, and the overall economy is better.
