Pure Lithium Corporation, established in 2020 in Boston, Massachusetts, specializes in developing advanced lithium metal batteries that offer significant improvements over traditional lithium-ion technologies. The company is led by CEO Emilie Bodoin and Chief Science Officer Donald R. Sadoway, an Emeritus Professor from MIT. Through its proprietary Brine to BatteryTM technology, Pure Lithium produces lithium metal anodes directly from brine sources, eliminating dependence on materials like graphite, nickel, cobalt, and manganese. This approach not only enhances energy density but also reduces production costs while improving safety and environmental sustainability.
Battery Technology
Pure Lithium’s innovative approach centers on their Brine to BatteryTM process, which creates pure lithium metal anodes with approximately ten times the capacity of traditional graphite anodes. When combined with their vanadium cathode technology, these batteries achieve twice the energy density while weighing half as much as conventional lithium-ion batteries.
The company’s technical achievements include developing pouch cells that have demonstrated over 2,200 cycles at 100% depth of discharge while maintaining more than 80% capacity. This performance metric represents a significant advancement in battery durability and commercial viability. Their batteries feature non-flammable components, including polymer and inorganic liquid electrolytes, substantially improving safety compared to traditional designs.
Pure Lithium’s manufacturing process reduces lithium metal electrode production costs by 90%, making their batteries more accessible for mass adoption in electric vehicles and energy storage systems. The company maintains a strong intellectual property portfolio with nearly 100 patents, including collaborations with Nobel Laureate Professor Sir Stanley Whittingham.
Recent Projects
In early 2024, Pure Lithium secured a joint development agreement with Saint-Gobain Ceramics to accelerate the production of lithium-selective membranes, essential for their brine extraction process. The company also acquired Dimien, expanding their vanadium cathode technology capabilities. Additionally, Pure Lithium received a foundational U.S. patent for their vertically integrated lithium metal and battery production technology, strengthening their intellectual property position.
Investors
Pure Lithium’s financial backing includes significant investments from Oxy Low Carbon Ventures (OLCV), which led their Series A funding with $15 million, potentially extending to $30 million. Energy Capital Group (ECG) has also invested in the company, with board member Robert Friedland leading the fundraising efforts. The company is preparing for a Series B round targeting $75-100 million in Q1 2025, with potential plans for an IPO.
