China's next-generation lithium-ion battery positive electrode materials made significant progress

According to the website of the Ministry of Science and Technology, with the support of the National Key R & D Program, the team of Professor Xia Dingguo of Peking University carried out research on new high specific energy manganese-based cathode materials, breaking through the limitations of traditional modification methods such as doping, coating, nano-morphology, An O2 configuration manganese-based lithium-rich power battery cathode material was prepared by combining LiMO2 phase with single-layer Li2MnO3 phase. This positive electrode material has a specific discharge capacity of more than 400mAh / g and a specific energy density of more than 1380Wh / kg, which provides the possibility of developing new lithium-ion batteries with a specific energy greater than 500Wh / kg. It is the highest ratio reported at home and abroad. Energy-density manganese-based lithium-rich cathode material for lithium ion batteries.

This research provides a new direction for the design of new high specific energy lithium ion battery cathode materials, and breaks through the limitations of foreign layered manganese-based lithium-rich material patents (O3 configuration). Development is of great significance. The research result "A High-Capacity O2-Type Li-Rich Cathode Material with a Single-Layer Li2MnO3 Superstructure (a high-capacity O2 configuration lithium-rich material with a single-layer Li2MnO3 superstructure)" has been in Published in Materials ("Advanced Materials").

Under normal temperature, Phosphoric acid is a colorless transparent viscous liquid, with a melting point of 21.1℃ and a boiling point of 158 ℃. As a tribasic acid with moderate acidity, it has all the common characteristics of an acid, including strong metal corrosion properties.


1.Phosphoric acid Electronic Grade is widely used in the semiconductor industry in ultra large scale integrated circuits, electronic chips, liquid crystal display films and cleaning and etching of said products. It is also used in the preparation processes of high purity special phosphates and high purity organic phosphorus products.

2.Phosphoric Acid Food Grade is used as a clarifier in food and beverage industries, as an acid additive or a yeast nutrient, and in the production of food grade phosphates.

3.Mainly used as a metal surface treatment agent, as the phosphate in raw material products, as an organic reaction catalyst in the sugar industry and as a refractory additive or a activated carbon treatment agent in the compound fertilizer industry.
