Pure Lithium is a Boston-based, vertically integrated lithium metal battery technology company that uses its Brine to Battery™ process to combine metal extraction and anode production. The company produces a pure lithium metal anode used in its lithium metal vanadium oxide battery, which it says offers step-change improvements in cell performance, cost, and safety versus today's lithium-ion technology. Its batteries are free of graphite, cobalt, nickel, and manganese. Pure Lithium is led by CEO Emilie Bodoin and CSO Donald R. Sadoway. The company plans to advance development of its first industrial-scale lithium metal vanadium battery manufacturing facility, and is pursuing project financing to support that build-out. Financially, the company has received a Letter of Interest from the Export-Import Bank of the United States for potential debt financing related to the project. Pure Lithium develops lithium metal batteries using its Brine to Battery™ process and manufactures pure lithium metal anodes for lithium metal vanadium oxide cells. The company combines metal extraction from lithium-bearing brines with anode production and says its cells avoid graphite, cobalt, nickel and manganese. Pure Lithium announced acceptance of a funding award from the U.S. Department of Energy’s Vehicle Technology Office to scale production of lithium metal anodes made from recycled lithium metal. It will partner with Argonne National Laboratory to recover lithium metal from an industrial waste stream and to demonstrate and scale its patent-pending anode production technology. Leadership includes founder and CEO Emilie Bodoin and MIT Emeritus Professor Donald R. Sadoway as full-time CSO. The company says the work aims to create a closed-loop, fully domestic supply source, secure commercially viable IP, and accelerate time to market. Pure Lithium develops lithium metal batteries and a Brine to Battery™ extraction technology that produces a battery-ready electrode in one day free of excess lithium, cobalt, nickel, manganese, and graphite. The company says its approach combines lithium extraction with novel battery technology to deliver high-performing lithium metal batteries at lower cost. Pure Lithium is led by CEO Emilie Bodoin and Donald R. Sadoway. The company extended its Series A in April 2024 with backers that included Ivanhoe Capital and WS Investment Company; the amount of the extension was not disclosed. Pure Lithium had announced a $15m Series A in March 2024 and intends to use the funds to expand operations and development efforts. Ivanhoe Capital chairman Robert Friedland commented that the combined extraction and battery technology could revolutionize the energy sector and improve sustainability and efficiency. Pure Lithium is a Charlestown, MA-based lithium metal battery technology company that develops a Brine to Battery™ extraction process to produce battery-ready lithium metal anodes in one day. The process sources lithium from aqueous brines and yields electrodes free of excess lithium, cobalt, nickel, manganese and graphite. Pure Lithium reports its lithium metal batteries have achieved over 800 charge and discharge cycles while retaining 97% capacity. The company is led by CSO Donald R. Sadoway and CEO Emilie Bodoin. Pure Lithium aims to commercialize lithium metal batteries via vertical integration across the entire value chain, from resource to battery. It has raised external capital to accelerate development and commercialization efforts.
