Who first proposed single crystal lithium manganate?

At present, most lithium manganate products are mixed and sintered by decomposed manganese dioxide and lithium carbonate, and generally retain the morphology of manganese dioxide, so the crystal morphology of lithium manganate itself is difficult to show octahedron.

Dr Yu Sun Cheng, the chairman of Qingdao Xinzheng Lithium Industry Co., Ltd., was the first to propose and prepare single crystal primary lithium manganate. After completing postdoctoral work in Japan in 2006, he returned to China to establish Qingdao Xinzheng. Single crystal primary granular lithium manganate technology is one of his achievements for many years.

In addition, the core technology of this achievement lies not only in the morphology of lithium manganate, but also in its modification technology. Through the effective doping of Al, the defects of high temperature performance of lithium manganate are effectively solved. Compared with many domestic manufacturers, the performance is not inferior to that of Japanese high-end lithium manganate.
