Ultrasonic Spraying Lithium Battery Diaphragm
Ultrasonic Spraying Lithium Battery Diaphragm – Cheersonic
A lithium battery separator is a thin film used in lithium-ion batteries that prevents the electrolyte from flowing out of the battery and protects the components inside the battery from damage. Lithium battery separators typically consist of multilayer polymer films, often including multilayer polyester films, multilayer polyurethane films, and multilayer polyethylene films.
The role of lithium battery separator
1. Positive and negative poles
The main function of the diaphragm is to isolate the positive and negative electrodes and prevent them from direct contact. If there is no diaphragm, a short circuit will occur between the positive and negative electrodes, leading to dangerous situations such as overheating, leakage, and explosion inside the battery.
2. Transfer ions
Although the separator separates the positive and negative electrodes, the battery needs to complete the transfer of charges through ion transport. Therefore, the membrane needs to allow the passage of ions and be able to control the flow speed and direction of ions.
3. Control temperature
When the battery is working, it will generate a certain amount of heat. If the temperature is too high, it will affect the battery life and safety. The separator of some high-end potassium-ion batteries can also control the temperature by adjusting the permeability
4. Prevent chemical reactions
In some cases, the positive electrode material will chemically react with the negative electrode material to produce gas or other harmful substances. The separator prevents these substances from mixing together, thus keeping the battery safe.
Advantages of ultrasonic spraying lithium battery diaphragm:
Ultrasonic spraying has the advantages of high spraying efficiency, low flow rate (controllable), uniform sprayed layer, small atomized particles, and online heating. Compared with traditional spraying methods such as high-pressure spraying, ultrasonic spraying equipment can control the speed and flow of spraying, and there will be no waste phenomena such as sputtering during the spraying process. The solution utilization rate is >95%, which reduces production costs and environmental pollution.
