Homogenesis 1. “Guide Directory” involves 4 new materials in the new energy sector, including high-performance lithium-ion battery diaphragm, nickel-watery-containing three-membered materials, a negative electrode material, high purity crystal hexafluorophosphate. 2 In recent years, my country’s lithium-ion battery positive material industry is constantly growing.
. The domestic lithium-electric positive material industry has a high concentration, has formed three major lithium-electric positive material industry bases in Beijing and Tianjin, Yangtze River, South China, South China..
3. The development of the downstream industry drives the industry to rise by the rapid development of lithium-ion batteries and its downstream industries, and the positive material of the lithium-ion battery is rapid..
As a key component of electric vehicles, the power lithium ion battery is one of the key components that affect the performance, cost and user experience of the vehicle. It is also the largest parts of the vehicle cost, which costs half of the cost of the whole vehicle cost..
From the perspective, the cost of the four major key materials of the positive material, the negative electrode material, the diaphragm and the electrolyte is more than 80% of the battery cost.. The cost of the positive electrode material also occupies about 40% of the total cost of lithium ion batteries.
. 4, technology constantly innovation relying on the key laboratory of Advanced Battery Materials in Yunnan Province, the technology of the Yunnan University of Science and Technology, is important to study the lithium-ion battery and key materials, and developed core technologies such as positive material, battery preparation and management of lithium-ion ternary batteries..
Since the “13th Five”, the new breakthrough in the technical development of the long life of the nuclear shell structure has improved the circulatory stability of high nickel positive materials.. With the support of the National Key R & D Plan, the Professor of Xia Dingguo, Peking University, conducted a new type of high-proportional energy manganese-based positive electrode material, breaking through the limits of traditional modification methods such as doping, coating, nano-morphology, and Limo2 and single layers Li2MNO3 is complemented by complexing of an O2 configuration of manganese-rich lithium battery positive material.
This positive electrode material has a discharge ratio capacity of 400 mAh / g and a more energy density of 1380WH / kg or more, which is possible to supply new lithium ion batteries that are more energy greater than 500Wh / kg. It is currently the highest than the most important than home and abroad. Energy density lithium ion battery manganese rough lithium positive material.
The study serves a new direction for the design idea of new high-proportion-to-energy lithium-ion battery positive electrode materials, and breaks through the limitations of foreign laminated mangrolic lithium material patent (O3 configuration).. Unfavorable factors 1, low-end products, high-end products are insufficient due to the importance of my country’s positive material production in low-end products, in some high-end products, such as high-performance three-yuan materials, etc.
. Therefore, the lithium-electric positive electrode material industry is currently in the overall stage, and the future important driving force comes from the demand of power lithium batteries..
And in terms of product distribution, low-end products are overproduced, and high-end products are inadequate.. 2, and Japanese and Korean advanced companies have a certain gap with a certain amount of production and a popularity material company in Japan, my country and South Korea, the main material company in other countries in China is generally small, and the products are also simpler, so the above Three major giants recognized in the Global Positive Materials Industry in Three Kingdoms.
Japan and South Korea has developed earlier in the positive material industry, and has been committed to high-end positive material products such as three-yuan materials in recent years, and domestic aspects, due to many reasons, lithium-electric positive material industry industry in the past development center is concentrated in phosphate Lithium, in the past two years, with the development of the new energy automotive industry, the state and the company gradually attaches great importance to the development of the three-yuan material industry, but there is still a certain gap between Japanese and Korean advanced companies in technology.. 3, alternative risk lithium-ion battery positive material industry industry products are updated fast, performance requirements continue to improve.
In addition, alternative technologies such as fuel power batteries, lithium sulfur batteries, although the large-scale industrialization is still waiting for time, but does not rule out the risk of replacing existing products in the future.
