General introduction

  A New Energy Technology Co., Ltd. in 2017 was established in Beijing Haidian District. It is a high-tech enterprise focused on high performance lithium battery materials and next-generation battery technology research and development and production, in the secondary battery area Ten international leading patents. The company has signed a scientific and technological cooperation agreement with the Institute of Chemistry, Chinese Academy of Sciences, and established a joint R & D center to promote the key materials and technical research in lithium batteries in lithium batteries. The company has a wholly-owned subsidiary Jiangxi Jinxin Energy Technology Co., Ltd., covering an area of ​​more than 100 acres, in the production line of thousands of ton batteries, main business sectors involving battery materials development, production and sales and battery technology development and technology transfer.

  The company is based on the development of lithium battery materials and technology, and looks at the key material and technology in the future, focusing on battery materials and products with higher energy density and power density, long cycling, safe cycle. The company adheres to the innovation of science and technology, leading future concepts, and grows forward to new energy technology companies with core competitiveness. The company's vision is to contribute to the development of China's new energy industry, and promote the China New Energy Industry Technology Innovation Revolution.

  Silicon is an inorganic compound, which is SiO, and normal temperature is normal for black brown to loece amorphous powder, melting point 1702 At ° C, boiling point 1880 ° C, density of 2.13 g / cm centimeter, is hard to dissolve in the mixed acid of dilute hydrofluoric acid and nitric acid and exogenous silica, and produce a white silica powder when heated in air. The silicon monosyl monoxide is not stable, and oxidized into silica in the air. When the silica vapor is slowly condensed, it will be reversened and copied into silicon and silica. Generally it can be produced rapidly from silicon at a high temperature of 1300 ° C in vacuum.

  SiO2 + Si → 2SIO.

  For a good volume of silicon oxide (SiO), people tried to use it as a lithium-ion battery negative electrode material. Generally, the SiO negative charge and discharge electric mechanism is as follows:

  SiO + Li → Li2O + Si (1)

  SiO + Li → Li4SiO4 + Si (2)

  Si + Li → Li4.4Si (3)

  The generated Li2O, Li4SiO4 is precipitated by the skeleton network, which acts as a good in situ buffer matrix, effectively inhibits the volume effect of the active metal silicon particles during charge and discharge; the two also supports support and dispersion metal silicon aggregation zone The role of particles avoids the aggregation phenomenon of finely disinjected metal silicon aggregation zone in the later charge and discharge cycle, which is advantageous for circulating stability. This is also the main reason why Silicon Oxa Material has been optimistic, the most important reason for the next generation of negative materials in reality.
