China's new lithium-ion battery will be industrialized in 2020
On the 17th, the reporter learned from the 9th International Conference on New Lithium Battery for Electric Vehicles (ABAA9) that by 2020, China's new lithium-ion battery will be industrialized, and the power battery will be intelligently manufactured, and the product cost performance will be greatly improved.
According to Shuguang, deputy director of the High Technology Research and Development Center of the Ministry of Science and Technology, the current production of lithium-ion battery in the world is mainly concentrated in China, Japan, and South Korea, among which Chinese companies have the largest number and the largest production capacity.
"At present, China has formed a relatively complete lithium-ion battery industry chain system, mastering the formulation design, structural design and manufacturing process technology of power batteries, and the production line has gradually transitioned from semi-automatic to fully automated large-scale manufacturing." .
Dawning pointed out that China's lithium-ion battery companies still have a large gap with advanced foreign companies in high-end materials and related basic research, as well as battery safety, reliability and system management technology.
According to reports, during the "Twelfth Five-Year Plan" period, China's lithium-ion power battery has a specific energy of more than 160 watt-hours per kilogram, and the cost is less than 3 yuan / watt-hour. According to "Made in China 2025", by 2020, the specific energy of lithium-ion batteries in China will reach 300 watt-hours/kg.
As a power battery widely used in new energy vehicles, lithium battery technology has greatly affected the development of the new energy automobile industry.
"For a long time in the future, China Energy Conservation will focus on popularizing new energy vehicles such as plug-in hybrid vehicles and pure electric vehicles . Therefore, the next step is to improve the intelligent manufacturing level of power batteries and improve the verification test methods and standards system. It is a key task for the development of China's power battery," said Shuguang.
Chopped Graphite/Graphite Electrode in different materials have different definition of graphite pieces, some data and literature is not very big graphite particles are called graphite pieces (such as Graphite Powder) some is graphite products have a certain size, for graphite broken into patches, we here say of graphite for a second, usually called graphite blocks. Graphite is produced from graphitization and machining process of graphite products. It is used as additive and conductive material in the manufacture of graphite waste in steel and foundry industries, and can also be processed according to customer's requirements. They are also widely used in electric arc furnaces (steelmaking) and electrochemical furnaces (metallurgical and chemical industries).
Main use of graphite
Graphite pieces due to its low ash content, conductive and heat conduction performance is good, so there are a wide range of USES, can be added to the formula of less ash or dust products, graphite broken broken into small particles commonly use. Ingredients to add a certain amount of graphite, the plastic paste after kneading, especially during extrusion can reduce the friction resistance paste to squeeze the mouthpiece, to improve the coefficient of pressure type. Graphite pieces of coal adsorption properties of asphalt is better, to join the carbon block can rise to reduce the "short" waste (i.e., the product after roasting top produce honeycomb structure), and can improve the thermal conductivity of the carbon block and alkali corrosion resistance. The electrode paste used in hermetically-sealed thermal furnace is added to a certain amount of graphite to increase the conductivity and thermal conductivity of the electrode paste and accelerate the sintering speed of electrode paste. When the graphite is ground into small particles or fine powder, it is also used as raw material for the production of graphite chemical equipment (such as graphite-resin tubes). The graphite can also be used as a carbon addition agent for the electric furnace.
Graphite classification
1. Raw and broken. It is a raw blank that is not qualified after molding.
2. Roasting is the cutting debris that is recovered after the roasting of raw billet and after inspection of unqualified waste and the processing of calcined products.
3. The graphite is broken, and it is inspected by the graphite-producing waste and the cutting debris produced by graphite products in the process of processing.
