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 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's 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. The prismatic anode-free cell is produced with approximately half of current cell manufacturing equipment for equivalent capacity, allowing sharply reduced scale-up cost.

Join this session with ONE CTO Steven Kaye, where he will explain that anode-free cells typically have low cycle life compared to conventional cells, and thus have not been considered practical for automotive applications, however, ONE's 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.
