  1. Lithium mine environmental protection technology and equipment

    Lithium mine environmental protection technology and equipment

    Jiangxi, China, has the world's largest lepidolite mine, with approximately 1.1 million tons of lithium oxide reserves, accounting for more than 30% of the country's lithium resource reserves. Jiangxi mica also contains rubidium and cesium, and the converted oxide reserves are about 400,000 tons and 54,000 tons, respectively, which have important strategic value. However, due to the low lithium content in lepidolite ore, high fluorine and potassium content, and complex mineral structure, traditional lithium extraction methods have high energy consumption, large solid waste, and great environmental pressure. Elements such as rubidium, cesium, and potassium in minerals cannot be used well, and the cost of extracting lithium is relatively high. At present, this worldwide problem has been broken. A new high-efficiency and high-environment-friendly lepidolite mine comprehensive utilization process technology and automation equipment project was completed and implemented in Jiangxi Nanchang Andeli

  5. What does the lithium battery processing pack manufacturer do

    What does the lithium battery processing pack manufacturer do

    From civil digital and telecommunication products to industrial equipment, military power supply and lithium digital batteries are widely used and used in batches. Therefore, lithium ion batteries are usually used in series and parallel for products with different voltages and capacities. The special battery formed by the protection circuit, housing and output is called pack. Pack can be a single battery, such as mobile phone battery, digital camera battery, MP3, MP4 battery, etc., or a series parallel combination battery, such as notebook computer battery, medical equipment battery, communication power supply, electric vehicle battery and standby power supply.

  7. How are the battery packs made in large battery factories

    How are the battery packs made in large battery factories

    Here, you can feel SAIC GM's concept and attitude towards battery and safety.
    As the "heart" of new energy vehicles, power batteries affect many performance indicators such as vehicle performance, endurance and safety.
    If you can't master such a heavy weapon in your own hands, you will be very passive. In short, GM also thinks so. It directly establishes its own battery factory in China and takes the initiative in its own hands.
    This is also the first time for me to enter the battery factory of SAIC GM. through this factory trip, we can see how the batteries of traditional big factories are made.
    The place we want to go is SAIC GM power battery system development center, which was established in Jinqiao, Pudong, Shanghai in 2015. It is the second battery assembly center of GM in the world and the first battery assembly center
