High energy density lithium battery technology -Lithium - Ion Battery Equipment
High-energy-density lithium-ion batteries are a key research and development direction in my country, and also a disruptive change in the field of new energy. my country proposed in the "13th Five-Year" new energy vehicle pilot project "High Specific Energy Lithium-ion Battery Technology", a common key technology research project, that by 2020, the battery cell energy density ≥ 300, the cycle life ≥ 1500 times, the cost of ≤0.8 yuan/Wh, the safety performance meets the requirements of the national standard. The "Made in China 2025" issued by the Ministry of Industry and Information Technology requires that the energy density of power lithium-ion battery cells is expected to reach 350 Wh/kg in 2020.
Silicon has the highest theoretical lithium intercalation capacity and low delithiation potential. It has received extensive attention due to its abundant resources, better rate characteristics, and environmental friendliness. Silicon-based anode lithium battery is the key development direction of my country's lithium battery in the future, and whether high-capacity silicon-based anode materials can significantly improve the volumetric energy density and mass energy density of lithium-ion batteries, meet the comprehensive technical indicators of various applications, and eliminate the volume The negative impact of swellability is the key to realizing the technological take-off of my country's new energy vehicle power battery and many application fields.(Lithium - Ion Battery Equipment)
my country's research and development of silicon-based composite anode materials has a long history, but the progress is relatively slow, especially the key technologies and preparations still need to be further improved and breakthroughs. At this seminar, experts from Chinese Academy of Sciences, Tsinghua University, Nankai University, Shanghai Jiaotong University, Beijing Institute of Technology and other scientific research institutions and domestic well-known lithium battery research and development companies focused on basic scientific issues in silicon-based anode materials, nano-silicon, Silicon oxide and other forms of silicon precursors, silicon-based anode materials with different microstructures and compositions, high-level manufacturing technology and manufacturing equipment for precursors and composite materials, and suitable electrolytes, conductive additives, and adhesives for silicon anode applications , composite graphite anode materials, various cathode materials, design, manufacture, formation process, electrochemical performance, safety performance of high energy density cells, test methods and test standards for silicon anode materials and cells, and the current use of silicon anode materials Discussions and exchanges were held on the level of various technical indicators of lithium-ion batteries and the possible limits in the future.
According to Liu Ronghua, CEO of Graphite State, there are still many obstacles in my country in terms of silicon-based anode materials. Graphite State will give full play to its own resource advantages to build a platform for government, industry, academia and research to provide one-stop efficient and high-quality services for scientific research units and enterprises in the aspects of research and development, patent application and protection, and achievement transformation, and jointly promote the silicon-based anode material industry. development of.
