Recently, at the Chinese Academy of Sciences' (CAS) second-quarter press conference, it was announced that several power battery cells developed by CAS have achieved energy densities of over 300Wh/kg, placing them among the world's most advanced levels. my country's power lithium batteries have moved from core technology to large-scale application, providing crucial technical support for the development of long-range electric vehicles, drones, and deep-sea exploration.
How important is battery energy density? Experts say that the driving range and reliability of a pure electric vehicle largely depend on the energy density within the battery. For example, taking BAIC's EV200 model as an example, if the energy density of a single battery cell reaches 300Wh/kg, assuming other technologies remain stable, it means the car's driving range could increase from the current 200 kilometers to 470 kilometers. Currently, researchers are optimizing battery pack integration in preparation for vehicle demonstrations; key lithium battery materials have entered the pilot production stage, and partnerships have been established with more than 30 battery and electric vehicle companies, striving to begin supplying batteries as soon as possible.
This achievement is just one of the major outputs of the "Transformative Nanotechnology Manufacturing Technology Focus" strategic pilot science and technology project. Since its implementation in 2013, this project has also combined nanomaterials with printing technology, abandoning the traditional photosensitive imaging approach in printing plate making, and forming a green printing industry chain technology that includes green plate making, green plate base, and green ink. Experts say that the promotion and application of these achievements is expected to reduce annual pollution from millions of tons of plate making waste liquid, tens of millions of tons of plate base waste liquid/slag, and hundreds of thousands of tons of volatile organic compound (VOC) emissions. Furthermore, "nanohealth technology" has been successfully applied to the development of in vitro diagnostic products and nanomedicine formulations. For example, the inflammatory nanofluidic immunoassay chip, which combines the detection of three inflammatory markers, can quickly distinguish between bacterial and viral infections, determine the stage of infection, and provide a basis for the scientific and effective use of antibiotics, which can largely avoid the overuse of antibiotics.
