Taiwanese battery developer ProLogium Technology is expanding beyond electric vehicles into construction equipment, unmanned systems and data centers, pursuing a commercialization strategy that combines high energy density and fast charging with safety and scalable manufacturing.
The company is positioning Taiwan as its base for technology development and manufacturing validation, France as a hub for large-scale production, and Japan as a potential manufacturing base through its partnership with Kyushu Electric Power.
In an interview with WindTAIWAN and ENERGY NIPPON during SMART ENERGY WEEK in Japan in September, founder and CEO Vincent Yang said bringing next-generation batteries to market requires more than improving performance. Safety, manufacturing costs and the economics of real-world use must advance together.
From Specialty Batteries to Larger Applications
Founded in 2006, ProLogium began with batteries designed for applications requiring thin profiles, flexibility or operation in specialized environments. It later expanded into consumer and automotive electronics.
According to Yang, interest from European automakers in the batteries’ safety characteristics helped spur the company’s move into larger batteries for vehicle propulsion.
His approach centers on safety while treating materials development, manufacturing and sales as parts of a single process. Because the business needs product revenue to sustain itself, the company has considered equipment, production processes and mass-manufacturing methods from the earliest stages of materials and cell design, he said.
ProLogium says it has shipped more than 2.4 million lithium ceramic battery cells since starting commercial production in 2013. Its experience includes supplying automotive audio systems and delivering approximately 10,000 battery sample cells for automotive applications.
Those shipments demonstrate manufacturing and customer support experience, but they remain distinct from large-scale adoption in passenger EVs. Batteries used for propulsion face different capacity requirements, operating conditions and validation standards. Deployment in mass-produced vehicles requires automaker qualification, reliable supply and competitive costs.
Measuring Performance at the System Level
In September 2026, ProLogium announced that it had begun mass production of its Gen 3.5 all-solid-state lithium ceramic batteries at its GWh-scale factory in Taiwan.
According to TÜV test results released by the company, a large-format, 185.4 Ah cell achieved a gravimetric energy density of 381 Wh/kg and a volumetric energy density of 903 Wh/L.
Higher energy density could allow batteries to become smaller and lighter while storing the same amount of energy. For vehicles, robots and aircraft, that could create greater flexibility in packaging, payload and range.
Separately, materials released in June outlining ProLogium’s collaboration with OPmobility cited a charging time of approximately 6.4 minutes from 5% to 80% state of charge, a cycle life exceeding 1,200 cycles, and retention of more than 95% of discharge performance at −20°C for batteries using a superfluidized, all-inorganic electrolyte system.
Those figures concern a different technology and evaluation context from the Gen 3.5 test results. Charging times and range in an actual vehicle also depend on battery pack design, charging infrastructure and operating conditions.
Yang sees an opportunity to rethink how EV batteries are sized. If fast charging, low-temperature performance and energy efficiency improve together, manufacturers could use smaller packs to maintain convenience while reducing vehicle weight and overall costs.
Cell performance alone, however, does not determine a finished product’s competitiveness. Additional structures needed to apply pressure or secure cells within a pack can erode advantages in weight, volume and cost. The relevant measure, Yang said, is performance across the entire system.

Gen 4 Targets Reactions That Can Trigger Thermal Runaway
Battery safety extends beyond whether an electrolyte is flammable, Yang said. It also requires consideration of how cathode and anode materials react under abnormal conditions, whether flammable gases are generated, and how a failing cell could affect neighboring cells.
ProLogium’s fourth-generation technology, which remains under development, is named the “Gen 4 All Inorganic Superfluidized Solid State Lithium Ceramic Battery.” It combines an all-inorganic, superfluidized electrolyte system with the company’s Active Safety Mechanism, or ASM.
According to ProLogium, ASM is designed to stabilize electrode materials at abnormally high temperatures to help prevent thermal runaway. Yang described it as a mechanism that renders materials inactive under abnormal high-temperature or high-voltage conditions, permanently shutting down the battery.
The company does not expect a single battery design to suit every application. Equipment requiring high-temperature tolerance has different needs from systems prioritizing low-temperature performance or fast charging. Technology selection must reflect those requirements.
On the manufacturing side, ProLogium emphasizes that Gen 3.5 and Gen 4 share its “Logithium” cell architecture and major production processes. Gen 3.5 uses a composite solid electrolyte system, while Gen 4 moves to an all-inorganic electrolyte system while retaining the underlying architecture. The company also expects improvements in low-temperature performance and reductions in materials and manufacturing costs.
ProLogium estimates that modifying approximately 10% of its existing GWh-scale production line and associated equipment would allow it to manufacture Gen 4 batteries.
The strategy aims to limit the investment needed for the technology transition by using existing assets. Gen 4 nevertheless remains in the industrialization phase, and the company has not announced the start of commercial mass production.
Unmanned Systems and Construction Equipment Take Priority
ProLogium’s approach to market entry depends on which performance attributes customers are willing to pay for.
Passenger vehicle manufacturers are highly sensitive to battery prices. In some industrial applications and high-value facilities, however, safety, uptime and operating efficiency can carry greater weight in purchasing decisions, Yang said.
For 2026 and 2027, the company plans to prioritize unmanned systems and construction equipment at its Taoke factory in Taoyuan, Taiwan. In parallel, the facility will support the production and validation of A- and B-sample batteries for EV, marine and aerospace applications.
When those larger applications move into full commercial production, ProLogium plans to use its French factory to meet future volume requirements.
From 2028 onward, the company intends to broaden Taoke’s production focus to include battery backup units, or BBUs, for AI data centers, as well as robotics. Over the longer term, it sees the factory serving as an Asia-Pacific production and supply hub for those applications.
For data centers, Yang said, fitting sufficient backup power into limited space requires evaluating power output, volume, safety and heat generation together. If a battery can reduce thermal loads and accident risks, its economic value cannot be measured solely by its purchase price per unit of stored energy.
In aviation, ProLogium signed a memorandum of understanding in June with Dutch electric aircraft developer Elysian Aircraft. The companies plan to assess the compatibility of existing battery technology with aircraft systems and validate dedicated designs tailored to aviation requirements.
Development targets include pack-level energy density of approximately 320–420 Wh/kg and a flight range of roughly 750–1,000 kilometers. These are development objectives, not performance figures demonstrated in commercial aircraft.
Building a Japanese Manufacturing Base With Kyushu Electric
In Japan, ProLogium is broadening its relationship with Kyushu Electric from technology and project collaboration into a strategic partnership that includes equity investment.
The company has brought Kyushu Electric on board as a strategic investment partner and plans to develop the relationship in stages.
The first stage calls for introducing ProLogium battery modules to the Japanese market and establishing local module production capabilities. That effort builds on its construction equipment collaboration with Kyushu Electric and Nakayama Iron Works, as well as the development of a 24-volt lithium ceramic battery module.
A subsequent stage would bring downstream cell manufacturing processes to Japan, linking them with local module production. The goal is an integrated supply chain spanning downstream cell manufacturing and module assembly.
Production scale, investment details and implementation timing will be disclosed later, the company said.
Yang emphasized Japan’s expertise in materials and precision manufacturing. ProLogium aims to extend cooperation into equipment, production processes and research and development, connecting technological capabilities with practical applications.
French Factory Targets Commercial Shipments in 2029
Construction of ProLogium’s factory in Dunkirk, northern France, began in February 2026.
Yang said proximity to European customers was one factor behind the location decision, alongside electricity supply, the carbon footprint of manufacturing and government support.
Under the company’s schedule, initial production ramp-up would take place between the fourth quarter of 2028 and the first quarter of 2029. Full-scale mass production and commercial shipments are planned for the second quarter of 2029.
Annual capacity in the first phase is expected to increase gradually to 4 GWh by 2030.
On financing, ProLogium said it had signed a definitive business combination agreement with Translational Development Acquisition Corp. and filed a Form F-4 registration statement with the U.S. Securities and Exchange Commission.
Subject to shareholder approval and other closing conditions, the company expects the transaction to close in the fourth quarter of 2026, with a Nasdaq listing under the ticker symbol “PRLG.”
ProLogium plans to use the proceeds to fund construction of the Dunkirk factory, expand its Gen 4 business, and develop applications including data centers and humanoid robots. It also intends to maintain technology development and manufacturing validation in Taiwan while advancing partnerships and application development in Japan.
Combining Intermediate Products With Manufacturing Licenses
ProLogium’s international expansion strategy also includes a production model that would extend beyond factories it owns.
Under that model, ProLogium would handle upstream manufacturing and supply an intermediate product called “Inlay,” incorporating its electrolyte, ceramic separator, cell architecture and safety technology.
Partners would use Inlay in licensed downstream manufacturing processes to produce application-specific cells locally, then integrate them into modules and packs.
The approach is intended to keep core technology within ProLogium while expanding manufacturing capacity closer to end markets. The company said it would announce specific Inlay supply agreements and downstream manufacturing license partnerships as they progress.
The next test for ProLogium is turning high-performance cells into products that can be supplied reliably at scale. That will require application-specific validation and a sustained manufacturing ramp-up.
Its strategy links technology development in Taiwan, large-scale production in France and industrial partnerships in Japan. Delivering on that network will now depend on execution.
