Graphene technology has made a major breakthrough

Recently, Northwest University has made many breakthroughs in graphene research and industrialization, making it possible to reduce battery size and increase capacity. At present, the research group has completed the industrialized amplification test of the graphene-modified graphite lithium battery anode material with a batch output of 500 kg, and the product performance has reached the national standard high-performance graphite anode material index. At the same time, the laboratory prepared a variety of anode materials of more than 1000mAh / g graphene lithium battery, in line with international research level.

China's graphene industry technology innovation strategic alliance predicts that by 2020, the scale of lithium-ion batteries and supercapacitors in the new energy industry will exceed 53.4 billion yuan; the market for flexible display and wearables in the electronic information industry will exceed 26.7 billion yuan. In the composite materials market, the market size of plastics, rubber, coatings and conductive inks will reach 37.2 billion yuan; the potential market in the fields of energy conservation, environmental protection and biomedicine will reach 10 billion.

As an important application field of graphene, lithium batteries can meet the requirements of energy density and power density of electric vehicles by introducing graphene technology, which will play an important supporting role in the promotion of new energy vehicles. The organization believes that graphene has excellent material characteristics and is widely used in biomedical and electronic materials. It has become the development focus of the “13th Five-Year” new materials. At present, a number of listed companies have accelerated their layout. Del Future (002631) builds a graphene industrialization platform by acquiring a leading graphene company to introduce R&D and industrialization teams. Huaxi Energy (002630) plans to acquire a 15% stake in graphene enterprise Hengli Shengtai for 1.35 billion yuan. The latter has a global low-cost single-layer graphene low-cost mass production process and multiple patents for graphene downstream applications, and is expected to achieve graphene. Full coverage of raw materials to applications.

Ultra-Precision Live Center, Ultra-precision High Speed Live Center, machine tool parts in machining. Tail with a taper shank, installed in the machine tool spindle taper or tailstock shaft hole, with its head against the workpiece cone. Can be used to face the complex parts and do not allow the central hole of the supporting parts. The top is mainly composed of a thimble, a clamping device, a shell, a fixed pin, a bearing and a core shaft. Thimble is the top of the inner hole of the center hole or pipe material, on the other end can be top end is a spherical or conical parts, thimble by the clamping device fixed. When the parts are not allowed or can not hit the central hole, the use of the clamping device to clamp the turning. The shell and the core shaft drill with pin hole, removing of the fixed pin pin or, to achieve the top two. Top can also be used for the work of the drilling, casing and hinge hole.

We are specializing in the production of Live Cente, we can to figure to sample processing, and perfect after-sales service and technical support. Looking forward to your cooperation!
