(executive Deputy General Manager of Wang Zhengqiang Tianyuan Group, Chairman and General Manager of Yibin Libao), Round Table Forum: focus on forward-looking technological innovation and insight into the development of the industry.
With the excellent characteristics of high energy density, high safety and long cycle life, all-solid-state battery is regarded as the next generation battery technology with the most potential for development.
At present, all-solid-state battery technology in the industry is in full bloom, which is accelerating the innovation and industrialization of all-solid-state battery technology system, and the commercialization schedule of all-solid-state battery for some enterprises is also gradually clear.
Based on this, the round table forum aims at the key material system of power battery, the R & D and upgrading of monomer and system structure, and the next generation technology research and judgment, to build a high-end dialogue platform in the professional field, around the core hot topic of “all-solid-state battery R & D and industry progress”, to study and judge the mainstream technology route, and share scientific research achievements and practical experience in industrialization.

Li Jin, head of Battery Research and Development Department of Guangqi Ean New Energy vehicle Co., Ltd., Liu Fangyang, Vice Dean of School of Metallurgy, Central South University, Yu Huigen, Chairman of Beijing Weilan New Energy Technology Co., Ltd., and Zhu Gaolong, director of Sichuan New Energy Automobile Innovation Center, attended the round table.
At the meeting, the participants had a heated discussion on the topics such as the solid-state battery technology route, the development stage, the mass production time node, the application scene and so on.
Yu Huigen believes that it is necessary to focus on the consistency of cell performance in the large-scale production and application of solid-state batteries, which is a key prerequisite that solid-state batteries can really be used as automotive power batteries and e-vtol batteries.
He said that from the current progress in tackling key problems, the capacity of all-solid-state batteries can reach the level of 5-10Ah, and small-scale verification is expected to be carried out in 2027.
Li Jinze believes that there are still many technical difficulties to overcome for solid-state battery loading applications, and he judges that the year 2027-2030 is the stage of small-scale demonstration operation of solid-state batteries.
In addition, he believes that if the problem of low-pressure operation of solid-state batteries is solved, solid-state batteries may take the lead in the application of 3C and e-vtol products.
Zhu Gaolong said that judging from the current progress of the industry, it is possible to achieve a small-scale production application in some areas around 2027, but the cost is expected to be high and the technology is in a relatively early stage.
For the optimization of the electrolyte system of all-solid-state battery, Liu Fangyang believes that the composite of polymer and oxide is an important technical measure to improve the conductivity of polymer electrolyte.
Yu Huigen suggested that halides are used on the positive side, sulfides are used in the middle layer, and oxides and polymers are used on the negative side, which can learn from each other’s strengths and give full play to the advantages of various electrolytes.
Li Jinze believes that in order to meet the performance requirements of vehicle gauge-grade batteries, the multi-component composite electrolyte route based on sulphide electrolyte is more likely to take the lead in application.
Zhu Gaolong said that although there are still many technical difficulties in the sulphide all-solid-state battery, through gradual improvement, the sulphide system is still regarded as an important choice with the prospect of industrialization.
Lu Shigang concluded that the participants made an in-depth interpretation of the time node of all-solid-state battery industrialization from the perspective of technology, market and competition, and from the overall development trend at home and abroad.
It mainly supports two technical routes, the sulfide-based route and the polymer / oxide composite route.
He said that just as there was a dispute between ternary and lithium iron phosphate in the early development of liquid batteries, solid-state batteries are now facing such a problem stage, and he judged that the technological routes of sulfides, oxides, polymers and halides will develop in parallel in the future.
