The research report of Shenwan Hongyuan Securities pointed out that there are many difficulties in the application of Solid-state battery. The first is to reshape the supply chain. Compared with the existing mature liquid lithium battery technology, Solid-state battery has undergone tremendous changes. It is necessary to reshape the already extremely complex lithium battery supply chain. The second is to reduce costs. The production costs of new scientific and technological materials such as pre lithiated silicon carbon negative electrode or prospective metal lithium negative electrode, high nickel positive electrode and solid electrolyte used in Solid-state battery are far higher than those of current corresponding materials, and the cost reduction process is extremely arduous and long. Thirdly, the fast charging performance is poor.

Liang Rui pointed out that the development of the Solid-state battery industry should be a gradual transition process from the current liquid lithium battery to the semi Solid-state battery and then to the all solid state battery. It has become the industry consensus that the existing technology and equipment can be used.

"It is expected that all Solid-state battery can be commercialized before 2030, or between 2025 and 2030, which is more realistic," Liang Rui said.

Xu Xingwu, senior vice president of Guoxuan High tech Power Energy Co., Ltd., previously disclosed that Guoxuan High tech will introduce Solid-state battery technology from 2020 to 2022; In 2022, Solid-state battery technology will be upgraded iteratively to produce high safety Solid-state battery.

Feng Sihan, CEO of Volkswagen Group (China), said at the 2020 Volkswagen China Performance Communication Conference that at present, Volkswagen, Toyota and other companies are developing a new generation of Solid-state battery. Our judgment on the mass production of Solid-state battery is basically the same as that of Toyota, which will be from 2023 to 2025.
