Michigan-based energy storage company Our Next Energy (ONE) has unveiled a 240 Ah prismatic anode-free cell after a 12-month R&D effort. ONE says the new technology will enable the commercialization of its Gemini dual-chemistry architecture, which will be integrated into a BMW iX prototype vehicle later this year.
ONE says its 1,007 Wh/L cell eliminates the need for graphite and anode manufacturing equipment, and predicts that the savings could bring cell costs to as little as $50 per kWh at scale. “Our prismatic anode-free cell is produced with approximately half of current cell manufacturing equipment for equivalent capacity, allowing us to sharply reduce scale-up cost,” said Mujeeb Ijaz, founder and CEO of ONE.
ONE explains that anode-free cells typically have low cycle life compared to conventional cells, and thus have not been considered practical for automotive applications. The company says its Gemini dual-chemistry architecture enables the use of anode-free cells by reducing cycle and peak power requirements by 90%.
ONE’s Gemini system pairs standardized LFP and anode-free chemistries into one battery pack—a proprietary DC-DC converter enables each chemistry to focus on different functions: LFP for daily driving and anode-free to extend range for long distances.
“Scaling 100x from a 2 Ah pouch cell to a 240 Ah prismatic in less than 12 months is a testament to the simplicity of the design and ability to use conventional Li-ion production equipment,” said Dr. Steven Kaye, ONE Chief Technical Officer. “Gemini will reach volume production in 2026, accelerating EV adoption by delivering 600 miles of range.”
