HE3DA

What HE3DA does

HE3DA s.r.o. is a privately-held Czech battery technology company founded in 2013 and headquartered in Prague, with operations extending to a manufacturing facility in Horní Suchá operated by its exclusive partner Magna Energy Storage (MES) and a US branch office. The company has developed a proprietary nanotechnology platform for lithium batteries based on 3D spatial electrodes and a nano-ceramic separator, enabling electrode thicknesses up to 2 mm and individual cells up to 100 kWh — roughly two orders of magnitude larger than conventional lithium cells. The architecture delivers a claimed 5,000+ cycle life, inherent non-flammability, and 100% recyclability, with international patents in 65+ jurisdictions (including a core separator patent running to 2042) and certifications covering TÜV transport and safety as well as Intertek US market compliance.

The product portfolio spans the core HE3DA Technology Platform plus multiple derivatives: Robusta cells (1 kWh and 1.3 kWh) for grid and renewable integration, a Thin-Wall/Pancake battery for trucks and heavy machinery, 24V/48V automotive starter batteries, fast-charging EV cells (520 Wh/L, 125 Wh/kg), the modular PowerBox (15–30 kWh), DC/DC fast-charging stations, and a special-series line targeting aerospace and medical micro-batteries. Revenue is generated through technology licensing to MES combined with hardware sales of cells and complete storage systems, sold via direct B2B relationships, installation partners (e.g., Maister Karlovy Vary), and exhibition-driven demand. Primary customer segments are energy/utility and automotive enterprises, with secondary exposure to aerospace, defence, and residential backup. Named commercial deployments are limited in number and skewed toward pilot/validation sites (Camp David Ranch in Nevada, Czech polar station at Svalbard), suggesting the company is still in a pre-scale commercialisation phase relative to its 15–30 GWh aspirational capacity.
