Bump three yuan precursor production line started to prove safety of new energy solutions for automotive battery materials
Recently, in the field of waste battery recycling has been dormant for five years of Bump announced the group's cycle Science Park - cycle Bump Technology Co., Ltd. Hunan own R & D of lithium-ion battery ternary composites precursor production line was started, annual output will reach 1,500 tons, which means that waste battery recycling Bump to the input to the output of high-end storage battery materials circulation industry roadmap has been formally opened, and to achieve the next stage of the new energy automotive battery materials solution has laid a solid foundation.
It is understood Bump has completed the "Utilization of used batteries project" Science and Technology Park, the whole cycle of a project building three production lines, namely, nickel wire, and ternary cobalt-wire line. Cobalt-nickel wire which line was able to produce up to 2009, cobalt, nickel product is already fully market. Recently, the ternary Bump just completed production line is mainly dealing with ternary spent lithium-ion batteries and cathode materials, nickel-cobalt-manganese composite oxide production (cell level), ternary material 130 tons per month.
Danone has been coupled with a comprehensive line of nickel and cobalt production lines Bump the current system in the Hunan-based products will be fully covered by the general precursor materials used rechargeable batteries market. Bump from the recycling of used batteries from the industry, and the physical layer by layer to get through the decomposition of waste batteries, wet, fire, law, chemistry and metallurgy processing channel, and developed its own unique high-end storage battery materials synthesis technology to realize the secondary battery into the battery waste material recycling mode. This shows that the Bump is a potential for new energy vehicles to provide a true sense of the economic model of the raw material recycling solutions.
China's solar industry and strive to break through technical barriers
At present, China's solar industry had previously been dependent on exports, but under the influence of the economic crisis, are turning to the growing Chinese domestic market. As of January 2010, China has more than 10 domestic large-scale power stations start 1MW and above, in the future there will be more projects ready for implementation. The industry's attitude is "thin-film solar cells on the active challenge, and strive to overcome technical barriers." For businesses with their own technology, the field there is a huge business opportunity.
Shanghai Jiao Tong University in China in 2020, the amount of solar power into making a bold prediction: "will greatly exceed 20GW, also is expected to reach 200G ~ 500GW".
Reduce the cost of hydrogen fuel cell catalysts Bacheng
Technical University of Berlin researchers and scholars from the United States jointly developed a new platinum alloy, this new catalyst could save a lot of precious metals platinum, so that the chemical reaction of hydrogen fuel cell cost reduction 80%, the results of this study published in the latest issue of "natural chemical" magazine.
As one of the new clean energy hydrogen fuel cell, in addition to an alternative to traditional diesel and gasoline engines, but also widely used in power supplies, and portable electronic devices such as notebook computers. Hydrogen fuel cell works is an electrochemical process is actually in the process combining hydrogen and oxygen, releasing electricity and water will not cause any pollution to the environment. To make this process fast and efficient, you need a lot of precious metal platinum as a catalyst. However, platinum materials are expensive and scarce resources is, therefore, the development of hydrogen fuel cell research is the key to efficient low-cost alternative to platinum catalyst.
The researchers mixed the platinum and copper, and then removed from the platinum-copper alloy part copper, only a few nanometers in diameter spherical platinum catalyst particles of copper, platinum and copper particles inside this spherical copper, shell is only a few atoms thick platinum , thereby greatly reducing the amount of platinum used. The researchers confirmed that the copper-platinum metal by removal of part of the mix and the process of copper, platinum can make the surface of the catalyst alloy particle density of the arrangement of atoms much closer than the average platinum. This unusual structure of these particles reduces the oxygen atoms binding to make platinum alloy catalysts with better performance than the pure platinum catalyst, hydrogen fuel cell manufacturers to greatly reduce the cost.
The researchers further tests proved that the surface of platinum catalyst changes in the structure, you can optimize the catalytic activity. The project leader Peter Strasser pointed out that similar structural changes also apply to other precious metals, precious metals used to reduce the cost of the chemical process of universal significance. Researchers will further study other non-precious metals platinum and a combination of effects, in order to find a more excellent performance of the catalyst.
