Company profile
researched Aug 2026Navion Energy is a Los Angeles, California-based battery company developing proprietary sodium-ion cells and systems for commercial and defense applications. The company positions its chemistry as enabling TWh-scale energy storage using only U.S.-sourced materials, stating that its supply chain is 100% U.S.-based, uses no critical minerals, and targets roughly half the cost of lithium-ion batteries. Its stated product attributes include non-flammable, high-power, military-grade characteristics.
According to its investor profile with HAX, Navion's batteries use next-generation materials and are aimed at energy storage applications spanning auxiliary and backup power through to battery energy storage systems (BESS). The company is also developing an onsite rapid charging system based on sodium batteries for medium- and heavy-duty electric trucks; it describes an architecture combining low-voltage design with a specialized bidirectional DC-DC converter to charge deeply discharged sodium-ion cells, which most existing chargers cannot handle, and to avoid the need for expensive cooling.
The website lists a leadership team of Joon Lee (CEO), Rahul Gayam (CTO) and Dr. Sang Cheol Kim (CSO), with Dr. Joon Hyung Lee as an advisor, and describes the founders as power and energy veterans. The site advertises pre-orders for its products and open engineering and sales roles.
Business model
Navion Energy manufactures and sells sodium-ion battery products, presented as dual-use offerings for commercial and defense customers, with pre-orders solicited directly through its website. It also develops charging system hardware for medium- and heavy-duty electric vehicles.
Traction
Selected into the HAX 2024 cohort (SOSV) as a pre-seed company and named a CalSEED awardee for its sodium-battery rapid charging system for electric trucks; the company is taking product pre-orders via its website.
▸Full profile — market position, technology, go-to-market, geography, risks & controversies
Market position
An early-stage (pre-seed) entrant in sodium-ion energy storage, differentiating on domestic supply chain independence and cost relative to lithium-ion incumbents.
Claims a fully U.S.-based supply chain with zero critical minerals and approximately 50% the cost of lithium-ion batteries, together with non-flammable, high-power cell characteristics and charging technology compatible with deeply discharged sodium-ion cells.
Technology
Proprietary sodium-ion battery chemistry built with next-generation materials and no critical minerals, marketed as non-flammable, high-power and military-grade, and as supporting TWh-scale storage. The company also develops a sodium-battery-based onsite rapid charging system for electric trucks that pairs a low-voltage architecture with a specialized bidirectional DC-DC converter to charge deeply discharged sodium-ion cells without requiring expensive cooling.
Go-to-market
American industrial operators and mission-critical/defense users; energy storage applications from auxiliary and backup power to battery energy storage systems (BESS); and medium- and heavy-duty electric truck charging.
Geography
Headquartered in Los Angeles, California, United States, with a stated focus on U.S. supply chains and American industry.
Risks & controversies
As a pre-seed hardware company, Navion's publicly stated performance and cost claims (100% U.S. supply chain, zero critical minerals, 50% of lithium-ion cost) are company-provided and not independently verified in the available sources.
