Gelonghui, April 23 | Lushan New Materials (603051.SH) said on the investor interactive platform that in terms of key materials inside solid-state lithium battery cells, the company has developed a silicon-carbon anode functional bonding material (PAA) for solid-state lithium batteries. Silicon is currently one of the materials with the highest theoretical specific capacity known for anodes, and has abundant reserves and low cost. It is an effective solution for improving the energy density of lithium batteries, and is considered one of the ideal anode materials for high-energy solid-state batteries. However, silicon anode materials have the defect of large volume changes, which will cause a large expansion effect during the cycle, leading to a decrease in battery cycle life. The silicon-carbon anode functional bonding material (PAA) developed by the company not only has good dispersibility and excellent bonding performance, but also has excellent electrochemical dynamics and stability, can effectively suppress and solve the expansion effect of silicon-based anodes, greatly improve the cycle life of silicon-carbon anodes, and can be applied to bonding solutions for silicon-based anode sheets in liquid and solid-state lithium batteries. Based on the fact that the amount of PAA added to the silicon-carbon anode is 3%, it is expected that with the further development of silicon-based anodes, the PAA materials market has broad prospects and huge market capacity.
