Summary
ProLogium Technology is a Taiwanese solid-state battery developer, founded in 2006 by its own account, that says it introduced a 100% ceramic separator architecture in 2013. At CES 2026 it announced a “Superfluidized All-Inorganic” lithium ceramic battery with company-reported performance claims that have no published third-party data. In July 2026 it agreed a proposed Nasdaq SPAC merger (TDAC) and in September Mercedes-Benz began testing its Gen4 cells. It broke ground on a gigafactory in Dunkirk, France in February 2026 (about €5.2 billion, up to 48 GWh eventual capacity), with first-phase operations scheduled for 2028.

What It Is / How It Works
ProLogium is one of the few solid-state battery companies that has been building and refining the technology for two full decades, giving it a depth of manufacturing experience that most competitors lack. The company’s original platform used an oxide-based ceramic electrolyte with a 100% ceramic separator — a configuration it was first to commercialize at any scale in 2013.
The latest architecture, announced as “Superfluidized All-Inorganic” at CES 2026, integrates three components: a superfluidized all-inorganic solid-state electrolyte, an all-ceramic separator, and an all-silicon anode. The claimed ionic conductivity of 57 mS/cm at room temperature is a headline figure — conventional liquid electrolytes and sulfide solid-state materials typically achieve 10–12 mS/cm, making the claim roughly 5× higher. If reproducible in production cells, this would largely close the conductivity gap that has long been the main limitation of oxide-based solid-state designs.
The “superfluidized” descriptor refers to a processing innovation that gives the otherwise brittle ceramic electrolyte improved interfacial contact with electrodes — traditionally the weak point of oxide-based cells. No peer-reviewed or third-party data on this architecture was found as of October 2026.
The Dunkirk gigafactory is ProLogium’s first overseas GWh-scale facility. The plant will make fourth-generation all-inorganic lithium ceramic batteries. Groundbreaking took place in February 2026 and the first phase is scheduled to start operations in 2028; the French government supports the project, and ProLogium says it is prioritizing locally sourced equipment (Battery-News).
Notable Developments
- 2026-09-25: Mercedes-Benz begins testing ProLogium Gen4 “Superfluidized Inorganic” lithium ceramic cells at its own facilities and external institutes; no energy density or charging figures disclosed, no vehicle platform or series-production decision. electrive reports Dunkirk phase one at 4 GWh per year by 2030 and up to 44 GWh long term (Battery-News reported 48 GWh). Mercedes also holds a stake in Factorial. (electrive)

Key People
Vincent Yang — Founder and CEO
- LinkedIn: not found
- Role: Founder and CEO; has led ProLogium since founding in 2006; primary technical and commercial spokesperson; personally represented ProLogium at Choose France summit (invited by President Macron) after the €5.2B Dunkirk announcement
- Education: Not confirmed from public sources
- Career (reverse-chronological):
- ProLogium Technology (2006–present): Founder and CEO; built the company over 20 years from a small Taiwanese startup to the builder of the world’s first giga-level solid-state lithium ceramic battery factory (Taoyuan, Taiwan)
- Notes: Yang is unusual among solid-state battery CEOs in having spent his entire career at a single company he founded. He built ProLogium before the solid-state battery space attracted external capital, giving him two decades of institutional knowledge that competitors are still accumulating. No LinkedIn profile findable in English-language searches; he is most visible through press coverage and European government engagement (France Choose summit, EU investment announcements). No prior employer overlap with other documented founders identified.
Key Partner Organizations (not individuals — include for context):
- Mitsubishi Chemical Group — Materials development partner
- FEV Group (Germany) — Cell-to-module engineering partner; showcased LLCB module at CES 2026
- CEA (France) — French national R&D institution; partnering on removable and recyclable solid-state battery modules

Supply Chain Position
ProLogium operates at the Cell Manufacturing layer with its oxide-based solid-state cells. Unlike sulfide-based competitors (QuantumScape, Solid Power, Idemitsu/Toyota), ProLogium’s ceramic electrolyte does not require lithium sulfide as a precursor — its oxide chemistry uses different ceramic precursors (generally zirconia, LLZO-type materials, or proprietary compositions). Upstream materials partners include Mitsubishi Chemical Group (materials development) and FEV Group (module engineering). Mercedes-Benz is named as a partner in July 2026 coverage; its precise role is not described. Manufacturing is to be anchored at the Dunkirk, France gigafactory (groundbreaking February 2026, first-phase operations 2028). No sulfur/Li₂S supply chain risk applies; lithium metal for the anode is the primary upstream mineral requirement. Ceramic oxide precursor sourcing is not publicly disclosed.
Claim Verification
Claim: 57 mS/cm ionic conductivity at room temperature
Status: Unverified (company-reported; no independent peer-reviewed confirmation found as of October 2026)
Supporting sources:
- ProLogium CES 2026 announcement — Company’s own claim; no third-party measurement cited
Refuting / questioning sources:
- No refutation found; 57 mS/cm would substantially exceed the best published sulfide electrolytes (~10–25 mS/cm), making independent verification particularly important before treating the figure as established
Summary: Headline conductivity figure is self-reported at a product announcement with no peer-reviewed or third-party data as of this writing. Worth watching for published data or OEM validation reports.
Claim: First to commercialize 100% ceramic separator (2013)
Status: Unverified (self-reported “first”)
Supporting sources:
- ProLogium — states it introduced the world’s first next-generation architecture with a 100% ceramic separator in 2013
Refuting / questioning sources:
- None found; no external source in this review confirms the “first” claim.
Summary: The 2013 date is a company statement; the “world’s first” framing is not independently confirmed.
