Overview:Low energy density, poor fast charging performance, poor low temperature charge and discharge performance and poor safety are the four major bottlenecks in the development of lithium ion power batteries.

Low energy density, poor fast charging performance, poor low temperature charge and discharge performance and poor safety are the four major bottlenecks in the development of lithium ion power batteries. As far as electrolytes are concerned, Lithium Manganese Dioxide battery for digital cameras are mainly liquid electrolytes, and lithium-sulfur and lithium-air batteries have become research hotspots, but their industrialization is difficult. In fact, if the industry will overcome the problem of all-solid-state lithium battery, and then do lithium-sulfur, lithium-air battery, the related technical problems will be solved. "In addition to the problem of rapid and low-temperature charging of the battery, 1, the anode material - increase the lithium ion diffusion coefficient; 2, the electrolyte - improve the lithium ion low temperature activity; 3, the battery preparation process - shorten the lithium ion transport channel; 4, conductive additives - Increase electronic conductivity and ionic conductivity.

Regarding the anode material, the most widely used graphite material is currently. For other negative materials, Professor He said that although the new nano-carbon materials have higher specific capacity, they need to solve the problem of low Coulomb efficiency and no charge and discharge platform (from the polarization mechanism, it is difficult to solve); new Si, Sn Composite anode materials have been widely studied, but if the first Coulomb efficiency can be further improved, it will have great development prospects; anode SEI film formation will become a research hotspot in the future to improve anode materials and battery performance.
