Guangzhou Automobile Construction Co., Ltd.China’s first large-capacity all-solid-state battery production lineAnd the launch of small batch trial production marks that solid-state batteries have officially left the laboratory and entered a new stage of industrialization. It will drive the upgrading of the entire chain of materials, equipment, and components, and become an important starting point for localization to break through.
1. Core technology breakthrough: dry process + solid electrolyte
- structural innovation: No liquid components, all-solid design, greatly improved safety
- Negative dry process: Three-in-one pulping, coating and rolling to reduce energy consumption and improve efficiency
- solid electrolyte: The heat resistance exceeds 300~400℃, which is far better than the 100℃ upper limit of traditional electrolyte, fundamentally solving the risk of thermal runaway.
2. Opportunities in the industrial chain: Materials and equipment took the lead in breaking out
1. Surge in demand for core materials
- Domestic substitution of solid electrolytes has been implemented, and demand is rapidly increasing with mass production
- Promote upgraded materials such as high-capacity electrodes and ultra-thin copper foilBoth volume and price rise
- Upstream materials companies usher in a window period for collaborative expansion
2. Comprehensive replacement of special equipment
- Traditional wet process production lines need to be modified and replaced, and the demand for dry process electrodes, electrolyte film forming and other equipment has exploded.
- Lianying Laser: Orders for semi-solid-state equipment are hundreds of millions of yuan, and orders for all-solid-state equipment have been received
- Pioneer Intelligence: Solid-state battery equipment revenue in the first quarter of 2025A significant year-on-year increase of 210%, the world’s scarce full-process equipment supplier
3. Three major bottlenecks of industrialization
- Material shortcomings: Sulfide is susceptible to moisture, oxide resistance is high, and polymer energy density is low
- Low process yield: Insufficient yield in key processes30%
- Cost is too high: Current cost for traditional lithium batteries3~5 times
These bottlenecks also point out the direction of research and development and substitution for materials, equipment, and process control component companies.
4. Commercialization Timetable and Application Scenarios
- 2026:Small batch loading test
- 2027~2030: Gradually scale up mass production
- Priority for implementation: high-end new energy vehicles,eVTOL flying car, energy storage, consumer electronicsAmong them, eVTOL has extremely high energy density and safety requirements, and is expected to become the first large-scale implementation on the track.
Conclusion
Solid-state batteries open up a new trillion-level track, which is not only a battery revolution;
Materials — Equipment — Componentsopportunities for comprehensive localization.
Companies that lay out core materials, special equipment and supporting semiconductor devices in advance will occupy a dominant position in this round of industrial change.
