Tianshi Kefeng Closes Tens of Millions of Yuan in Pre-A Funding Round

Funding Overview: Oriza Seed Fund Leads Round to Accelerate Hundred-Ton Production Line

Wuhan Tianshi Kefeng New Energy Technology Co., Ltd. (hereinafter referred to as "Tianshi Kefeng") recently announced the completion of a pre-A funding round worth tens of millions of yuan, led by Oriza Seed Fund with follow-on investment from Tianhong Capital. Qichen Capital served as the long-term financial advisor. The proceeds will primarily be used for product R&D and the construction of a hundred-ton-scale production line.

Founded in December 2022, Tianshi Kefeng focuses on the R&D and production of sulfide solid-state electrolyte powder materials, with technology incubated at Wuhan University of Technology and Justus Liebig University Giessen in Germany. As an upstream powder material supplier for sulfide solid-state batteries, the company has already reached leading battery cell customers and over 40 top universities both domestically and internationally. It has established a ton-scale production line and expects to commission a hundred-ton-scale line and achieve over 100 million yuan in revenue by 2026.

Technical Highlights: Achieving Both High Ionic Conductivity and Air Stability

On the technology front, Tianshi Kefeng has developed sulfide electrolyte powders with good air stability and a room-temperature ionic conductivity of 12 mS/cm. The company has also launched an LPSCB-based composite electrolyte membrane with a room-temperature ionic conductivity of 3 mS/cm and a thickness of just 20μm. These breakthroughs in two core metrics mean the company has achieved the dual goals of "high ionic conductivity" and "air stability" in the sulfide solid-state electrolyte field, addressing a long-standing technical pain point for the industry.

Company founder and Chief Scientist Wang Shuo is an associate professor at Wuhan University of Technology, with over 10 years of dedicated research in sulfide solid-state electrolytes and all-solid-state batteries, holding more than ten related patents. According to Wang, the company's founding was directly driven by market demand — a sulfide all-solid-state battery cell R&D company could not find suitable high-conductivity powder materials on the market, while the team's small-batch products developed in the university lab demonstrated excellent test results, creating the opportunity for commercialization.

Industry Context: Solid-State Battery Sector Continues to Heat Up

Solid-state batteries are widely regarded as a core direction for next-generation power batteries. The sulfide pathway, with its high ionic conductivity comparable to liquid electrolytes, has become one of the key technology routes that industry players are betting on. Currently, international giants such as Toyota and Samsung SDI are accelerating their efforts toward mass production of sulfide solid-state batteries.

However, the supply capacity of upstream sulfide electrolyte powder materials has remained a critical bottleneck constraining industry development. Only a handful of domestic material companies possess stable mass production capabilities. Tianshi Kefeng, leveraging its technological expertise and production line development, is gradually filling this market gap.

Future Outlook

With the completion of this funding round, Tianshi Kefeng will accelerate the construction and commissioning of its hundred-ton-scale production line, further consolidating its first-mover advantage in the sulfide solid-state electrolyte materials sector. Against the backdrop of accelerating global solid-state battery commercialization, the value of upstream core material suppliers is becoming increasingly prominent, and Tianshi Kefeng is well-positioned to secure a significant role in this fast-growing sector.
