Diaphragmless solid state lithium battery technology release and mass production planning

On November 7, Tailan New Energy and Changan Automobile jointly released the "diaphragm free solid state lithium battery technology", the first in the industry to promote the lithium battery "material reduction manufacturing" concept, to achieve the polar plate composite solid electrolyte layer diaphragm function replacement, ionic conductivity greater than 1.5mS/cm, and can be rolled. In addition, the mass production schedule of diaphragm free solid-state smart battery products is clear.

In the technical release, Tailan New Energy Chairman &CTO Dr. Gao Xiang released the diaphragm free solid state lithium battery technology. Too blue first promoted the concept of "reduced material manufacturing" of lithium batteries, bringing a revolution in the industry paradigm.

Its 4-3-2-1 technical route: On the basis of the four main materials of lithium-ion batteries, the first step is to reduce the diaphragm and part of the electrolyte for the first mass production and loading of semi-solid batteries; The second step, remove all the electrolyte, for low-altitude economy and other fields of solid products; The third step is to reduce the negative electrode for future negate-free all-solid-state products, and determine the industrial path from liquid to semi-solid and all-solid-state batteries.
