Ultrasonic spraying equipment: the innovative force for lithium battery performance upgrade
At the moment when the new energy industry is developing rapidly, lithium batteries, as the core of energy storage, have attracted much attention for their performance improvement. From consumer electronics such as mobile phones and laptops to new energy vehicles and energy storage power stations, the requirements for the energy density, safety and cycle life of lithium batteries are constantly increasing. As the key link in optimizing the performance of lithium batteries, Cheersonic’s ultrasonic spraying equipment has brought new breakthroughs to the lithium battery industry with its unique advantages.
In the production and manufacturing of lithium batteries, the quality of the electrode coating directly affects the battery performance. Traditional spraying methods have limitations in controlling the thickness and uniformity of the coating, and it is difficult to meet the increasingly stringent production standards. Cheersonic’s ultrasonic spraying equipment uses high-frequency vibration to atomize the slurry into uniform and tiny particles, and accurately sprays them on the lithium battery electrodes. This precise spraying method can achieve ultra-thin and highly uniform coatings, effectively increase the load and distribution uniformity of electrode active substances, and thus increase the energy density of lithium batteries.
In terms of diaphragm coating, ultrasonic spraying also shows strong advantages. As a key component in lithium batteries that isolates positive and negative electrodes and prevents short circuits, the surface properties of the diaphragm are crucial to battery safety and cycle stability. Using ultrasonic spraying equipment, functional coating materials can be evenly coated on the surface of the diaphragm to form a coating with high porosity and good lyophilicity, which can enhance the electrolyte wetting ability of the diaphragm, reduce the internal resistance of the battery, and increase the cycle life. At the same time, the uniform coating can also avoid the decrease in diaphragm strength caused by uneven local thickness and improve the overall safety of the battery.
In addition, ultrasonic spraying equipment also plays an important role in applications such as lithium battery tab coating and battery shell anti-corrosion coating. By spraying a conductive coating on the surface of the tab, the contact resistance can be reduced and energy loss can be reduced; spraying an anti-corrosion coating on the battery shell can effectively resist environmental erosion and extend the battery life.
Compared with traditional spraying equipment, Cheersonic’s ultrasonic spraying equipment is more competitive in material utilization. Its precise atomization and spraying control greatly reduces the waste of slurry and reduces production costs. In terms of environmental protection, ultrasonic spraying produces less waste gas and waste liquid, which conforms to the concept of green production and provides support for the sustainable development of lithium battery companies.
As the lithium battery industry develops towards high energy density and high safety, ultrasonic spraying equipment has become an important boost to the upgrading of lithium battery production processes with its advantages of high precision, high uniformity, and high material utilization. Cheersonic will continue to innovate and use advanced ultrasonic spraying technology to promote continuous breakthroughs in lithium battery performance and inject new momentum into the development of the new energy industry.
