High purity alumina coating technology: can solve the problem of the loss of the first cycle capacity of lithium batteries.

On September 23rd Altech Chemical Australia announced that its high-purity alumina coating technology for lithium-electric negative (graphite, silicon carbon, etc.) materials was approaching Dacheng. It is said to solve the "first cycle capacity loss" key problem facing the lithium battery industry.
first popularize industry knowledge SEI membrane, full name solid electroly teinterface, solid electrolyte interface (membrane)

. As the name implies, he is a passivation film layer with solid electrolyte properties. It is formed in the process of the first charge and discharge of lithium battery, mainly in the negative pole. Because the formation of SEI membrane consumes some lithium ions, the irreversible capacity of the first charge and discharge is increased, which reduces the charging and discharge efficiency of the electrode material.
many battery manufacturers are exploring ways to prevent lithium ions from reacting on the lithium-ion negative pole to produce SEI membranes, thereby reducing lithium consumption. Altech Chemical says it has developed a high-purity alumina composite as a lithium electrode coating that can significantly reduce the formation of SEI membranes. "We have the potential to leverage Altech's alumina coating products and technologies to take lithium-ion battery performance to the next stage. The commercialization of this process will be an important step in the evolution of lithium-ion battery anodes. Iggy Tan, managing director of the company, said in a related press release that a breakthrough in this technology has been made.
that the project is currently in the independent verification phase, the whole process will continue until the end of the year, and then will apply for commercial patents.
