Lithium-ion batteries do not contain heavy metal cadmium, which greatly reduces environmental pollution compared to nickel-cadmium batteries. Lithium-ion batteries have been widely used in portable electronic devices such as mobile phones and laptops due to their unique performance advantages. They have greatly reduced the weight and volume of these portable electronic devices and greatly extended their use time.
With the shortage of energy and the requirements of environmental protection, large-capacity lithium-ion batteries have begun to be used in electric vehicles. It is expected to become one of the main power sources of electric vehicles in the 21st century, and will be used in artificial satellites, aerospace and energy storage. Therefore, the demand for lithium batteries is growing.
Vacuum technology is also used in the production of lithium batteries. Electrolyte is an important component of lithium-ion batteries. Before injecting electrolyte, the container needs to be evacuated to a vacuum so that the electrolyte can fully contact the two electrodes. Usually, there is excess electrolyte needing to be pumped out. As electrolyte will damage the vacuum pump, a gas-liquid separator is needed to prevent it from entering the vacuum pump. In addition, if there is water inside the lithium battery, it will expand during use. Therefore, manufacturers generally use vacuum baking to remove the water. This process also uses a gas-liquid separator.
The above are the vacuum process used in the lithium battery industry. LVGE has been established for 12 years. During these years, we has contacted with customers from various of industries, but we cannot know every industry well. All we can do is keep learning and improving our products and services. If you are also a practitioner in the lithium battery industry, you are welcome to share more professional knowledge with us.
