After becoming the first to commercialize solid-state batteries, ProLogium announced it will become a publicly listed company through a business merger with a special purpose acquisition company (SPAC).
Solid-state battery company ProLogium set to go public
For over two decades, ProLogium has been pushing to move solid-state batteries from the lab to the real world as it ramps up production.
Prologium has been a pioneer in the field since it became the first to successfully commercialize solid-state batteries with a 100% ceramic separator, replacing the traditional polymer film.
Last year, it revealed another breakthrough, introducing the world’s first superfluidized all-inorganic solid-state lithium ceramic battery.
ProLogium said on Wednesday that it’s “the only company globally that can publicly demonstrate a solid-state battery mass-production line,” and it’s about to tap into public markets as it ramps up production over the next few years.
The solid-state battery maker announced plans to list its shares publicly on Nasdaq through a business merger with Translational Development Acquisition Corp, a blank-check company, or SPAC.
Once the agreement is finalized, ProLogium’s shares will list on the Nasdaq under the ticker symbol PRLG. The deal is expected to close in the second half of 2026, valuing ProLogium at about $3.8 billion.
“This transaction is expected to provide us with the capital to fund our next phase of growth,” ProLogium’s Founder and CEO, Vincent Yang, said.
According to Yang, ProLogium will use the capital to “scale the production of our 4th-generation superfluidized inorganic solid-state batteries, advance the construction of our new gigafactory in Dunkirk, France, and support our expansion into adjacent application verticals including data centers, aerospace and robotics while continuing to progress in EVs.”
Since opening its first GWh-class gigafactory in Taiwan in May 2024, ProLogium has shipped out over 800,000 cells.
Construction on its first overseas GWh-class plant in France will begin by the end of 2026. The company plans to ramp up production between Q4 2028 and Q1 2029, with mass production and deliveries set to follow in Q2 2029.
According to independent third-party testing, ProLogium’s latest batteries achieved an energy density of 360 Wh/kg, about 50% above traditional lithium-ion batteries. UL Solutions ARC testing also verified that the solid-state batteries did not experience thermal runaway when using the Heat-Wait-Seek (HWS) method.
ProLogium is the latest solid-state battery manufacturer to list publicly via a SPAC merger to access public markets quicker without the hassle of a traditional IPO, following QuantumScape, Factorial Energy, and Solid Power.
