On January 9, NIO founder William Li announced that the company will mass-produce solid-state batteries, or more accurately, "semi-solid-state batteries," in 2022.
Even so, on January 11, the stocks of lithium battery separator and electrolyte companies faced increased pressure in the secondary market, resulting in a widespread decline.
The reason for this lies in the replacement of existing lithium battery separators and electrolytes by new technologies. True solid-state batteries, compared to the currently mainstream liquid lithium batteries, can use solid electrolytes instead of liquid electrolytes and separators, resulting in significant improvements in energy density and safety.
In other words, in solid-state batteries, the four major raw materials—positive electrode material, negative electrode material, separator, and electrolyte—will become three major raw materials: positive electrode material, negative electrode material, and solid electrolyte.
Therefore, it's easy to explain why the emergence of solid-state batteries has negatively impacted companies producing lithium-ion battery separators and electrolytes. Even semi-solid-state batteries have dealt a blow to companies producing lithium-ion battery separators and electrolytes.
