A Sodium-Ion Battery Built Differently
Sodium-ion unlike lithium ion are lower cost, safer, and can be made with the local supply chain. Traditional sodium-ion batteries are large and heavy, and many use hazardous materials. Prieto is different.
Prieto's patented architecture and manufacturing process solve both problems.
The result is a compact, lightweight, safe, high-performance sodium-ion battery that works across a wide range of demanding applications.

The Sodium Advantage, Evolved
Sodium is abundant, inexpensive, and available domestically. The United States holds the world’s largest reserves of soda ash, at 24.7 million metric tons, and sodium as a battery material costs a fraction of lithium.
The challenge for sodium-ion batteries has always been performance and size. Prieto’s patented battery design overcomes both limitations, delivering fast charging and discharging, high power output, and a compact, lightweight form factor that conventional sodium-ion batteries cannot match.

Unlike conventional lithium and sodium ion batteries, Prieto’s patented battery delivers.
- MADE IN USA
- LOW COST
- COMPACT DESIGN
Prieto’s sodium-ion platform is designed to support a U.S.-based, non foreign entity of concern (FEOC) supply chain as the industry matures.
Sodium costs a fraction of lithium, enabling genuinely competitive manufacturing economics.
Prieto’s design is small and light enough for portable and wearable applications, or stackable for large-scale critical infrastructure.
Prieto's sodium-ion batteries deliver power where reliability and safety are non-negotiable, including: backup power, energy storage, and defense.
Prieto’s sodium-ion batteries charge in under 10 minutes. That’s 2-4X faster than most lithium-ion batteries.
For backup power operations the system will be ready immediately upon a drawdown. For defense applications, it means completing the mission faster.
Most lithium-ion batteries’ performance degrades in extreme cold and present safety risks in extreme heat. Prieto’s sodium-ion batteries operate reliably from -70°F to 200°F, covering virtually every climate and operating environment on earth.
Prieto’s batteries are designed to be safe and to minimize thermal runaway risks. Prieto batteries are suitable for environments where lithium-ion is prohibited or restricted: hospitals, crowded facilities, enclosed military platforms, and dense data center deployments.
Prieto’s batteries can also be shipped at zero charge, simplifying logistics and reducing regulatory complexity.
Manufacturing-First.
