Stratus Materials develops manganese-rich, zero-cobalt cathode active materials for lithium-ion batteries aimed at delivering improved energy density, stability, safety, and lower cost. The company says its proprietary formulations and production processes overcome stability and cycling challenges that have hindered high-manganese chemistries. Its products are targeted primarily at light- and medium-duty electric vehicles and other applications with similar performance requirements. Stratus is scaling production and is currently producing its proprietary cathode active material at an early pilot scale while providing samples to a small group of potential initial customers. The company emerged from stealth in 2022 (previously operating as 33 Tech Inc.) and is led by CEO & CTO Dr. Jay Whitacre. In mid-2022 it completed a $12M Series A financing led by Breakthrough Energy Ventures with participation from DNS Capital.
