Company Overview

Stratus Materials Inc. is a United States-based developer and manufacturer of advanced cathode active materials for lithium-ion batteries. Founded in 2022 in Pittsburgh, Pennsylvania, the company creates manganese-rich, cobalt-free cathode materials to enhance performance, safety, and environmental sustainability in electric vehicles and energy storage applications.

Battery Technology

Proprietary manganese-rich cathode materials (LXMO class) that eliminate cobalt while maintaining high energy density and safety. Their manufacturing process uses specific formulations to overcome stability and cycling issues, supported by laboratory-scale and pilot-scale production facilities.

Products

Manganese-rich, cobalt-free LXMO cathode active materials delivering over 80% capacity retention after 1,000 full-depth discharge cycles, designed for light- to medium-duty electric vehicles with improved energy density and cost-effectiveness.

Recent Projects

Secured nearly $3 million DOE funding to develop PhosCAM, a high-energy-density composite cathode material; expanding pilot line to 30 tons/year capacity by 2024; LXMO materials undergoing validation testing by EV industry customers.

Investors

Raised $12M in Series A led by Breakthrough Energy Ventures, with participation from DNS Capital; received grant funding from the U.S. Department of Energy.
