(1) Renewal of graphite selection and mining technology equipment
my country's graphite mining technology equipment has basically no improvement since the 1960s, and has greatly lagged behind other mineral species in terms of energy consumption and mineral recovery. The graphite mining technology and equipment are simpler than other mineral species, but due to the low industry's long -term benefits and lack of funds, there is no update. The powerful mineral design and research institute combined with the selection enterprise to introduce advanced mining technology equipment of other mineral species, design and build advanced graphite selection mining production lines, in terms of energy consumption, recovery rate, large scales protection, water resources conservation and utilization, tail tail, tail The technical and economic indicators such as mining treatment have improved significantly. After successful operation, it is promoted in the industry, and advanced technology and economic indicators are used as indicators for industry access and elimination of backward technology equipment.
(2) Construction of advanced large -scale gifda purification production lines
Domestic and energy -saving advanced pH -purity methods and energy -saving high -temperature purification technology, government guidance, combination of production, research and research, and constructing different types of large types of large -scale gifda purification production lines for resource characteristics. Strictly restrict the use of hydrofluoric acid that severely pollute the environment in chemical purification.
(3) R & D of the industrial scale and power of the lithium -battery natural graphite negative material, the development of energy storage -type battery negative electrode materials
There are already enterprises that prepare negative materials after the scale of scales graphite spherical, such as Betry; Tsinghua University and other universities have the technology of preparing negative materials with micro -crystal graphite, but the industrial scale and product quality cannot meet the lithium ion battery The demand for rapid development. A large number of domestic spherical graphite produced in China is mainly exported to Japan and South Korea for foreign companies to produce high -quality negative materials. Relying on resources, the industrial scale of natural graphite lithium -ion battery negative materials, and in accordance with different grades of batteries, develop different quality negative materials to enable the product to be series; develop safe and long -lived natural graphite power type and energy storage battery negative electrode poles. Material. As the demand for lithium -ion batteries increases rapidly, the market prospects of negative electrode materials are very broad.
(4) The industrialization of natural graphite bases for same -sex graphite
The same -sex graphite is widely used in nuclear energy, silicon crystal preparation, electro -spark processing, continuous cast steel, aerospace and other fields. It is a high -end product and strategic material for charcoal materials. my country currently needed to be imported by 2/3 of the same -sex graphite. Traditional technology preparations are complicated and cost -effective. Micro -crystal graphite mineral particles itself has all -oriented sexuality. It is a good raw material for preparing the same -sex graphite, and it can simplify the craftsmanship and reduce costs. The samples of industrial size have been prepared. Graphite 1.05); After the scales graphite spherical, it also has potential possibilities to prepare the same -sex graphite. Tsinghua University and others have their own original patented technology, and they are cooperating with enterprises to implement industrialization
