24h Move is the share-price change in the day after each event; other market factors may also have contributed.
Recent J-Star headlines tied to leadership changes and PSSB agreements often saw strong positive reactions, but one earlier PSSB collaboration sold off despite seemingly constructive news.
Over the last few months, J-Star has repeatedly highlighted a strategic pivot toward U.S.-centric, higher-tech businesses. On Jan 6, 2026, it announced plans to exit China operations and expand automated U.S. manufacturing. Multiple releases since Jan 14, 2026 detailed collaborations with PSSB on solid-state batteries, including an exclusive distribution agreement that drew a 59.07% move. Leadership also shifted, with Jonathan Chiang returning as CEO, which coincided with a 10.91% gain. Today’s partnership deepens the same PSSB/U.S. expansion storyline.

Establishment of 100MWh Modular Automated Solid-State Battery Production Line in Texas
TAICHUNG CITY, Taiwan, May 01, 2026 (GLOBE NEWSWIRE) -- J-Star Holding Co., Ltd. (Nasdaq: YMAT) (“J-Star” or the “Company”), today announced it has formed a strategic partnership with Patriot Green Energy Technology Co., Ltd. (“PSSB”), a leading industry developer and manufacturer of next-generation solid state battery technology for high-performance and defense applications with a large minority ownership by Industrial Technology Research Institute (“ITRI”), to develop Made-in-USA polymer-based solid-state battery solutions. The collaboration includes plans to establish a 100 megawatt-hour (“MWh”) modular, automated solid-state battery production line in Baytown, Texas to support the growing requirements of the unmanned aerial vehicle (“UAV”) and drone sector.
J-Star and PSSB have jointly submitted a grant application to the U.S. Department of Energy to support the development of the facility. The project has also received a commitment letter from the Baytown Economic Development Foundation securing a parcel in the TGS Cedar Port Industrial Park for construction of the factory.
The initiative is aligned with the U.S.–Taiwan Agreement on Research and Technology (ART) framework, which provides a bilateral pathway for technical cooperation and outward investment clearances from Taiwan’s Ministry of Economic Affairs (“MOEA”). In January 2026, the United States and Taiwan signed a landmark trade and investment agreement with Taiwanese semiconductor and technology companies committing
Jonathan Chiang, CEO and Chairman of J-Star Holding, commented, “We continue to strengthen our relationship with PSSB with this new ’Made-In-USA’ initiative to develop a fully automated next-generation solid-state batteries production line in Texas. This partnership marks a major step in building a secure, friend-shored supply chain infrastructure and solutions in the United States. With strong government support and growing demand from aerospace and defense customers, we believe this positions J-Star at the forefront of advance battery manufacturing.”
Cheng Zhang Lu (Peter Lu), Chairman & CEO of PSSB, has committed to transferring the company’s full technical blueprint to the Baytown facility, including extended on-site technical residency, local hiring, and workforce training to support long-term operations. This partnership combines ITRI-backed innovation with U.S. manufacturing capabilities to accelerate the commercialization of polymer-based solid-state batteries and help establish a domestic production ecosystem for the rapidly growing UAV and drone markets.
Strategic Partnership and Market Opportunity
Through YMA (TX) INC., J-Star is leveraging PSSB’s venture backing from ITRI to pursue supply agreements with Tier-1 U.S. aerospace and defense OEMs. The partnership is designed to accelerate qualification with U.S. federal contractors by leveraging technology that has already undergone validation in Taiwan.
The project aims to establish a U.S. domestic, fully automated production line for high-density polymer-based solid-state batteries supporting the rapidly expanding UAV and drone markets. The facility is expected to scale manufacturing to 100 MWh annual nameplate capacity, targeting over 350 Wh/kg cell-level energy density while enhancing safety and supply-chain resilience.
Key Investment Highlights
- Targeting the
$50B + dual-use UAS battery market with strong long-term growth trends; - Proprietary NAEPE electrolyte chemistry and UV Snap-Cure heritage supported by 1,500+ global patents and R&D 100 Award-winning technology;
- Pathway toward Blue UAS approval supported by ITRI’s role in Green UAS certification;
- Phase 1 establishment of a 100MWh automated production line in Baytown, Texas, with multi-phase expansion plans; and
- Leadership team with 30+ years of global manufacturing, OEM sales, and capital markets experience.
The Baytown facility will include an ISO-7 certified ultra-dry room environment capable of maintaining a dew point of ≤-40°C. The production line will incorporate customized automation, including vacuum die-coating systems, solid-electrolyte molding, automated stacking, and pouch-sealing modules. The project is designed to transition from pilot-scale validation to a fully operational domestic manufacturing asset capable of supplying high-density power solutions to the UAV industry.
According to Research and Markets, the UAV battery market is expected to grow from
