Stratus Materials Emerges from Stealth to Launch Next-Generation Cathode Materials

PITTSBURGH, February 7, 2023 /Business Wire — Stratus Materials Inc., a developer and manufacturer of next-generation cathode active materials for lithium-ion batteries, came out of stealth today.  The company, previously operating as 33 Tech Inc., was founded in early 2022 to commercialize a set of highly promising, manganese-rich, cobalt-free cathode innovations by a team led by Dr. Jay Whitacre, a Carnegie Mellon University professor and serial entrepreneur. 

For years, the lithium-ion battery industry has been seeking the performance and cost advantages of a high-manganese cathode chemistry, but these cathodes have faced persistent challenges with stability and cycling.  Utilizing proprietary formulations and production processes, the Stratus Materials team has developed manganese-rich, zero-cobalt cathode materials that deliver outstanding functionality, energy density, stability, low cost, and input materials availability, overcoming the challenges that have hindered high-manganese systems to date.  The company is focused on scaling the production of these novel cathode materials, which are being specifically targeted at light- and medium-duty electric vehicles as well as other applications with similar performance requirements.

Jay Whitacre, CEO & CTO of Stratus Materials, said: “Our innovative processes and materials are designed to provide the lithium-ion battery industry with cathode offerings that outperform best-in-class NMC cathode formulations on virtually every dimension, without relying on cobalt and with significantly less nickel and lithium per kilowatt-hour.  We are extremely excited about engaging more broadly with potential customers and partners.”

In mid-2022, the company completed a $12M Series A financing led by Breakthrough Energy Ventures (BEV) with participation from DNS Capital. 

“Energy density, cost, materials availability, and safety are critical factors for a battery technology to enable full EV adoption and production,” said Carmichael Roberts, Breakthrough Energy Ventures.  “The Stratus Materials team has developed a set of cathode active materials that address and optimize each of these parameters, enabling EVs to scale to new levels.”

Stratus Materials is currently producing its proprietary cathode active material at an early pilot-scale and is providing samples to a small group of potential initial customers.  Representatives of the company will be attending the International Battery Seminar & Exhibit next month in Orlando, FL.  Please contact the company at info@stratusmaterials.com for more information or to inquire about a meeting.

Stratus Materials (www.stratusmaterials.com) is a U.S. based developer and manufacturer of next-generation cathode active materials for lithium-ion batteries.  Our mission is to offer a highly compelling combination of performance, safety, cost, and environmental impact to leading battery manufacturers and their downstream OEM customers.   Stratus is primarily focused on cathode solutions for light- and medium-duty electric vehicles and other applications with similar requirements.
