Iron is the fourth most abundant element in the Earth’s crust. U.S. iron reserves are 43,000 times greater than cobalt and 8,000 times greater than nickel. We believe abundance will lead to a stable local supply chain.
Iron as a raw material is lower in cost than nickel and cobalt. Iron has remained low in cost, over the past twelve months, while nickel and cobalt have doubled in price in the same period of time.
Nickel cobalt manganese (NCM) cathodes contain up to 33% oxygen, which feeds a rapid combustion event during an internal short circuit. Lithium iron phosphate (LFP) does not release oxygen, so it does not facilitate the same combustion.
Our iron-based Aries II has shown that it can match range and mass within six percent of NCM. Aries II provides industry-leading energy density and delivers more than 350 miles of range on a single charge.
Our iron-based Gemini technology enables 600 miles on a single charge, making it possible to handle real-world conditions, such as towing, high-speed driving and cold temperatures.
Aries LFP is built to last 5000+ cycles, charging to 100% everyday. That’s one tough battery. How do we know? We dropped it. Crushed it. Submerged it. Punctured it. To make sure this battery is not just up to industry validation standards, but ours, too.
ONE is building a North American supply chain. We began with abundant iron. We are now manufacturing our LFP packs here in Michigan. We make LFP cells in our 20 GWh factory, ONE Circle.
ONE is building cells, modules, packs at the largest US-owned and operated LFP factory with the most energy-dense LFP battery available on the market. Made with abundant iron.
