'The power battery is the core of the electric vehicle. In the current subsidy of electric vehicles, competition in other new energy vehicle technologies is fierce. To increase the energy density of the power battery and reduce the cost is the key to the sustainable development of the electric vehicle. The long-term power lithium battery project is responsible for Ren Li, a researcher at the Institute of Physics of the Chinese Academy of Sciences, introduced that under the special support of the Nano-pilot, the power density of a variety of battery cells developed by the Chinese Academy of Sciences reached 300Wh/kg (watt-hours/kg), ranking the world's advanced level.
What does this mean? The cruising range of a pure electric vehicle depends on the energy density of the battery to a certain degree. ' Take Beiqi's EV200 model as an example, if the other technology remains stable, if the battery cells With an energy density of 300Wh/kg, the cruising range of the vehicle is expected to increase from the current 200 kilometers to about 470 kilometers. Currently, researchers are conducting battery pack integration optimization to prepare for the loading demonstration. 'Li Wei explained.
Li Lan stated that the lithium battery key materials developed relying on the Nano Pilot have now entered the pilot phase, and the relevant research team has formed a cooperative relationship with more than 30 batteries and electric vehicles and other companies, and strives to achieve volume delivery at an early date. Energy Density Lithium-ion battery new generation of positive and negative materials, solid-state batteries, lithium-sulfur batteries, sodium-ion batteries, failure analysis technology for high-level power batteries, etc., China has also obtained a large number of original results, which laid a good foundation for the development of the next generation of power batteries. .
Nanotechnology is a new discipline emerging at the end of the last century. Its outstanding features are based on atomic or molecular assembly, manufacturing of new functional devices or nanostructures with unique biological effects. In recent years, it has also shown certain advantages in the diagnosis and treatment of major diseases. .
The nano-microfluidic immunochip in-vitro diagnostic technology developed by the project combines the characteristics of large specific surface area of nanomaterials with the advantages of rapid detection and high flux of microfluidic technology for joint detection of multiple indicators. There are 4 products that have obtained the national medical device registration certificate. 'The research leader of the Nano Health Technology Project, Shen Haiwei, a senior engineer at the National Nano Science Center, exemplifies the Inflammation Nanofluidic Immunoassay Kit, which combines the detection of three inflammatory markers. , Can quickly distinguish between bacterial infections and viral infections, determine the stage of infection, provide scientific basis for the effective use of antibiotics, can largely avoid the abuse of antibiotics. nano-fluidic immunoassay chip imager, also has a portable , Low cost, easy operation, etc., suitable for use with the chip for on-site testing.
In addition, the project team has also developed a new tuberculosis diagnosis technology and 'cancer catcher' technology. The new tuberculosis diagnosis technology has high specificity, and the product performance is better than imported kits; 'tumor catcher' technology is based on high affinity magnetic particles - Peptide nanomaterials have achieved efficient enrichment and detection of circulating tumor cells, and their product performance has been significantly better than that of domestic and foreign counterparts. In the research and development of pharmaceutical preparations, the project team completed the initial research and development of a number of nanopharmaceutical preparations. Some of the samples have been Enter the clinical examination and approval link.
'The important advances in nanotechnology in new energy vehicles, green printing, energy, and health have fully demonstrated the basic research's leading role and driving role in transformative industrial applications,' said Qi Tao, deputy director of the Science and Technology Task Force of the Chinese Academy of Sciences. The Nanometer Pilot Team will further focus on the major national needs and key technical issues of concern to the organization, organize the core R&D forces of China's nanotechnology, select key technologies in key areas to conduct research, and help China's new energy, new materials, advanced manufacturing, and other strategic emerging Industry innovation, green, energy saving, environmental protection, sustainable development.
