Lithium Battery

Improve electrode performance: Thermal spraying can evenly spray materials with high specific capacity and high conductivity, such as lithium cobalt oxide, lithium iron phosphate, etc., on the current collector to form a high-performance electrode coating. By precisely controlling the process parameters of thermal spraying, the electrode coating can have good crystallinity and pore structure, thereby improving the charge-discharge performance, cycle stability and rate performance of the electrode.
Preparation of new electrode materials: Different metals, alloys or compounds can be sprayed together to form composite electrode materials by using thermal spraying technology to meet the requirements of lithium batteries for high energy density and high safety.
Improve separator performance: Battery separators need to have good air permeability, ionic conductivity and mechanical strength. Thermal spraying technology can improve the performance of the diaphragm by spraying a coating with special functions, such as ceramic coating, polymer coating, etc., on the surface of the separator.
Enhance the barrier of the separator: A dense barrier layer is formed on the surface of the separator by thermal spraying, which can effectively prevent the micro-short circuit between the positive and negative electrodes inside the battery, and improve the safety and stability of the battery.
Improve corrosion resistance: During the use of lithium batteries, the battery shell may come into contact with various corrosive substances, such as electrolyte, moisture in the air, etc. Thermal spraying corrosion-resistant coatings, such as zinc-based coatings, aluminum-based coatings, etc., can form a dense protective film on the surface of the battery shell to prevent the shell from being corroded and prolong the service life of the battery. Especially in some harsh environments, such as high temperature, high humidity, salt spray and other environments, thermal spray corrosion-resistant coating can significantly improve the protective performance of the battery shell and ensure the safety and reliability of the battery.
Enhance electromagnetic shielding performance: With the continuous improvement of electronic products for electromagnetic compatibility requirements, lithium batteries need to have good electromagnetic shielding performance to prevent the electromagnetic signals inside the battery from interfering with external equipment, and also avoid the impact of external electromagnetic signals on battery performance. Thermal spraying metal coatings, such as copper coatings, nickel coatings, etc., have good conductivity and electromagnetic shielding properties, which can form an effective electromagnetic shielding layer on the surface of the battery shell, reduce the electromagnetic radiation of the battery, and improve the electromagnetic compatibility of the battery.
Repair worn parts: Some key components in lithium battery production equipment, such as the coating head of the coating machine and the roll of the roller press, are prone to wear and tear during long-term use, affecting the production quality and efficiency. Thermal spraying technology can repair these worn parts, and restore the size and surface properties of the parts by spraying wear-resistant coatings, such as tungsten carbide coating, boron nitride coating, etc., prolong the service life of the parts, and reduce equipment maintenance costs.
Improve the corrosion resistance of equipment components: The parts in the production equipment that come into contact with corrosive media such as electrolytes, such as electrolyte storage tanks, transportation pipelines, etc., are susceptible to corrosion. Thermal spray corrosion-resistant coatings can effectively protect these components, prevent corrosion leakage, and ensure the safety and stability of the production process.
