    On the 26th, it was reported that the world’s first 1,000-ton high-purity lithium chloride production line (hereinafter referred to as the project) produced by the Qinghai Salt Lake Research Institute of the Chinese Academy of Sciences in Xitai Jinel Salt Lake, Qaidam Basin, Qinghai, reached 99.
    5% of lithium chloride quality indicators.
    It marks the completion of this production line

    .
    The proven reserves of lithium chloride in Qinghai are over 22 million tons, accounting for about 83.
    4% of China's salt lake lithium resource reserves and one-third of the world's brine lithium resource reserves

    .
    Lithium chloride is mainly used in the field of air conditioning and in the production of dry batteries and metal lithium.
    Lithium chloride is the main material for preparing battery-grade lithium carbonate

    .
    Duan Dongping, deputy director of the Qinghai Institute of Salt Lakes, Chinese Academy of Sciences, introduced that the project is a sub-project of the key deployment project of the Chinese Academy of Sciences, "Extraction of Some Strategic Elements from Salt Lake Brine".
    It is jointly undertaken by the Qinghai Institute of Salt Lakes of the Chinese Academy of Sciences and the Shanghai Institute of Organic Chemistry.

    .
    It is understood that the project was put into production and trial run on December 24, 2015, and the production line was completed on January 21, 2016

    .
    "In the process of advancing the implementation of the 1,000-ton high-purity lithium chloride project, multiple units have jointly developed China's first centrifugal extraction device for extracting lithium from salt lakes

    .
    " Duan Dongping said that the project will gradually improve the process in the next three months Parameters and technical indicators, the ultimate goal is to achieve a 4N grade (4N refers to a purity of 99.
    99%) production line

    .
    Duan Dongping said that the construction of the project will have a demonstration effect on the extraction and recycling of strategic elements such as lithium and boron in China's salt lakes, as well as the conservation and efficient comprehensive utilization of salt lake mineral resources

    .
    It is also understood that in the past five years, Qinghai salt lake lithium extraction technology has made major breakthroughs.
    The industry has tried to use brine lithium production processes such as adsorption, calcination, and carbonization, which has laid the foundation for the large-scale development of Qinghai's lithium industry

    .
    In addition to salt lake brine extraction and extraction of 1,000 tons of lithium chloride technology and demonstration projects, Qinghai Salt Lake Industry Co.
    , Ltd.
    has built an industrial demonstration production line with an annual output of 10,000 tons of lithium carbonate; Qinghai Lithium uses ion selection after extracting boron from brine.
    Magnesium-lithium separation process directly produces battery-grade lithium carbonate, and builds a 10,000-ton grade lithium carbonate production device

    .
    Statistics from the China Association of Automobile Manufacturers show that in 2015, China produced 340,471 new energy vehicles and sold 331,092 new energy vehicles.
    Sales of new energy vehicles surpassed the United States for the first time, becoming the world's largest new energy vehicle market

    .
    Zhou Weixing, deputy director of the Qinghai Provincial Science and Technology Department, previously stated that technological innovation in the lithium industry is the focus of the 13th Five-Year Plan.
    Aiming at the different composition of valuable elements in various salt lakes in Qinghai, we will strive to pass unified standards to open up the process from lithium carbonate to new energy vehicles.
    Complete the industrial chain, and do a good job in the industrial chain of lithium chloride, metal lithium, and lithium hydroxide
