Should nations prioritize keeping battery technology supply chains within their own borders?
Draslovka has acquired the intellectual property portfolio for Prussian Blue and Prussian White Analogue sodium-ion battery technology from Natron Energy. The transaction, cleared by the Committee on Foreign Investment in the United States, secures patent rights extending into the mid-2040s.
Why it matters
The acquisition aims to establish a vertically integrated sodium-ion battery supply chain using Western-held intellectual property. By consolidating materials, cells, and systems IP, the company intends to scale production capacity across European and U.S. markets.
The acquisition secures a comprehensive patent and trademark portfolio for sodium-ion materials and battery systems that remains in force through the mid-2040s. This intellectual property covers the chemical architecture required for Prussian Blue and Prussian White Analogue batteries.
The players
Draslovka
A global producer of sodium cyanide and ferrocyanide feedstocks currently expanding its role in the sodium-ion battery supply chain.
Natron Energy
A developer of sodium-ion battery technology that has divested its Prussian Blue and Prussian White analogue intellectual property.
Altris
A Sweden-based sodium-ion battery material specialist that serves as a strategic partner for industrial-scale production in the Czech Republic.
Covoro Mining Solutions LLC
The United States subsidiary of Draslovka that operates a chemical manufacturing facility in Memphis, Tennessee.
Committee on Foreign Investment in the United States
The interagency committee that reviewed and granted clearance for the acquisition of the technology assets.
The details
Prussian Blue and Prussian White analogues are crystalline structures used as cathode materials in sodium-ion batteries, which utilize abundant sodium ions to store energy. Draslovka plans to combine this acquired intellectual property with its existing production of ferrocyanide feedstocks, the chemical precursors necessary for these cathode materials. The company operates a solid sodium cyanide plant in Memphis, Tennessee, and maintains a production line in Kolín, Czech Republic, alongside its strategic partner, Altris.

The Tech Race
This acquisition consolidates the intellectual property required for Prussian Blue Analogue battery manufacturing within a single Western-aligned supply chain. It signals a shift toward vertical integration as companies compete to secure the chemical patents necessary for non-lithium energy storage.
This transaction prepares the foundation for future industrial-scale sodium-ion cell production, though commercial availability timelines for new hardware remain unannounced. Developers and energy firms should watch for upcoming manufacturing capacity updates in the U.S. and Europe.
The takeaway
Draslovka is positioning itself to be a primary provider of the chemical feedstocks and IP necessary for the next generation of sodium-ion storage. Observers should track the company's progress on scaling cell manufacturing capacity in Kolín to verify if these patents translate into commercially viable output.
