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.

The Sodium Advantage, Evolved

The US holds the world’s largest reserves of soda ash, at 24.7 million metric tons. And sodium costs a fraction of lithium.

Unlike conventional lithium and sodium ion batteries, Prieto’s patented battery delivers. 

Watch Mike Rosenberg, Prieto’s Chief Executive Officer, explain why abundant, affordable sodium offers a compelling alternative to lithium for the future of battery technology.

Prieto's sodium-ion batteries deliver power where reliability and safety are non-negotiable, including: backup power, energy storage, and defense.

Charge in Minutes, Not Hours

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.
Made in America.

Prieto’s first facility is designed to be operational in a fraction of the time and with a fraction of the capital required by conventional battery manufacturers. Prieto’s electroplating process enables rapid scale through contract manufacturing using existing infrastructure.

Grounded in Science.
Driven by Purpose.

Prieto was born on breakthrough research by Dr. Amy Prieto with the goal of advancing energy independence with a technology built to compete and win in global markets.
