The research and development of high-performance power batteries is one of the important measures to promote electric vehicles. This morning, the reporter learned from the regular press conference of the second quarter of the Chinese Academy of Sciences that the power energy density of various power battery cells researched and developed by the Chinese Academy of Sciences reaches 300Wh/kg. Above, it is in the world advanced level; China's power lithium battery has entered the stage of scale application from the core technology, and will provide important technical support for the development of long-term electric vehicles, drones, deep sea exploration and other development.
How important is the energy density of the battery? According to experts, the cruising range of a pure electric vehicle depends largely on the energy density in the battery. Take, for example, the Beiqi EV200 as an example, where other technologies remain stable. Under the circumstances, if the battery cell energy density reaches 300Wh/kg, it means that the vehicle's cruising range can reach 470 kilometers from the current 200 kilometers. Currently, researchers are optimizing the battery pack for loading. Demonstration preparation; Lithium battery key materials have entered the pilot phase, and has formed a cooperative relationship with more than 30 battery and electric vehicle companies, and strive to start delivery as soon as possible.
This achievement is just one of the major outputs of the strategic lead technology for the “Focus on transformative nano-industry manufacturing technology.” According to reports, since the implementation of this special project in 2013, researchers have also abandoned the traditional printing through the combination of nano-materials and printing technology. The technology idea of plate-making photographic imaging has formed a green printing industry chain technology including green plate making, green printing plate base, and green ink. Experts said that the promotion and application of the above results will hopefully reduce the pollution of plate-making waste liquid of one million tons per year. Ten million tons of waste-based waste/slag contamination and hundreds of thousands of tons of volatile organic compound (VOC) emissions. In addition, 'nano-health technology' has been successfully applied to the development of in vitro diagnostic products and nano-pharmaceutical preparations. For example, Inflammation nanofluidic immunoassay chip, which combines three inflammatory markers, can quickly distinguish between bacterial infections and viral infections, determine the stage of infection, and provide scientific evidence for the effective use of antibiotics. Avoid the abuse of antibiotics.
