Sodium-ion has gone mainstream.
The United States has no domestic producer.
Until now.

37%of all the batteries deployed worldwide in 2035 will be sodium-ion, Morgan Stanley forecasts
27xgrowth in sodium-ion battery shipments forecast between 2025 and 2036, per Avicenne Energy
95%of the sodium-ion cell factory capacity announced worldwide is in China

America’s first sodium-ion cell plant. Production in 2028, four lines by 2032.

Lithium reserves are scattered across six continents.
Sodium reserves are in Wyoming.

The sodium comes from soda ash. The largest deposit on Earth is in Wyoming.

Natural soda ashLithiumNatural soda ash is the sodium source. Bubble size is each country’s share of world reserves. China makes the most soda ash today, mostly synthetic; the United States is the largest natural producer. USGS, February 2026.

One of the largest, most energy-dense sodium-ion cells in the world, built in America.

A large cell in an aluminum case, made from five common materials.

11NaSodiumFrom soda ash, as in glass and baking soda. 2.6% of the Earth’s crust.
26FeIronThe world’s most used metal.
15PPhosphateAs in fertilizer.
6CCarbonAs in charcoal.
13AlAluminumAs in cans.

Nothing scarce, and nothing that only one country supplies. Built to UL 9540A and UL 1973.

It cannot catch fire the way lithium can.
It works in any climate. It lasts twenty years.

Zerofire chain reactions. The failure that burns lithium batteries does not exist in sodium-ion chemistry.
-40 to 60 CArctic cold to desert heat, minus 40 to 140 F, without the cooling systems lithium batteries need.
