Sunwoda has recently unveiled the latest progress in its third-generation of all-solid-state battery technology. According to the company’s investor relations activity report, the first generation of semi-solid-state batteries have completed development, with an energy density exceeding 300Wh/kg. The second-generation of semi-solid-state battery cells have now entered pilot-scale testing, while the third-generation of all-solid-state battery has completed product program and process validation, achieving 400Wh/kg.
In recent years, market demand for high-performance batteries has continued to grow. As a star technology in next-generation batteries, solid-state batteries have attracted substantial capital and R&D investment, accelerating their path to commercialization.
Sunwoda began its solid-state battery R&D efforts as early as 2015 and has adopted a “parallel development” strategy across its three generations of battery technologies. This approach allows the company not only to prepare for mass production of the first-generation semi-solid-state batteries, but also to advance technical readiness and mitigate risks for the second and third generations.
These efforts have already yielded tangible results. Not long ago, Sunwoda announced that cumulative production of its semi-solid-state batteries has surpassed 8 million units since core technology finalization in March 2024, demonstrating strong technical transforming
capability and mass manufacturing strength.
Through coordinated innovation in materials, structure, and manufacturing processes, Sunwoda’s semi-solid-state technology systematically addresses key limitations of traditional batteries. It maintains over 70% of capacity and stable discharge performance even in extreme environments as cold as -30℃, and withstands rigorous tests such as crushing and impacting. The battery operates reliably across a wide temperature range of -30℃ to 60℃, making it suitable for diverse applications including household, outdoor, and industrial auxiliary scenarios.
The industrialization of solid-state batteries is now accelerating. Multiple battery manufacturers have announced the establishment or upcoming launch of all-solid-state pilot lines, along with clear mass production plans. Expectations for supply chain demand are rising, and breakthroughs in material-level R&D continue to emerge. Sunwoda’s mass production of consumer-grade semi-solid-state batteries marks a solid step forward in the application of solid-state batteries in consumer electronics and provides a clearer development pathway for the broader solid-state battery industry.
As widely recognized within the sector, solid-state batteries are expected to see early adoption in consumer electronics, where high energy density and lower cost sensitivity prevail, before expanding into power applications such as eVTOLs and robotics, unlocking new possibilities. Industry analysis projects that the incremental market size for all-solid-state battery equipment will reach 2.5 billion yuan (approximately $351 million US) by 2027, growing at a compound annual growth rate of 122% to about 27.3 billion yuan (approximately $383.3 million US) by 2030.
