August 29, 2025: Li metal battery company Pure Lithium said on August 25 it had been honoured by the American Chemical Society for its ‘Brine to Battery’ technology.

Pure received the 2025 Green Chemistry Challenge Award in the society’s chemical and process design for circularity category.

Pure said its technology seamlessly integrates lithium metal extraction and battery anode production, significantly reducing energy consumption and environmental impact associated with shipping materials.

The company said its Li metal batteries eliminate graphite. Instead, it extracts Li metal from lithium brine, which Pure said is abundant in North America, to create a lithium metal anode that completely replaces today’s graphite anode.

According to Pure, its batteries represent a step change in energy storage, with double the energy density of today’s lithium ion batteries. The company said it has achieved unprecedented cycle life in small pouch cells, upwards of 5,000 cycles.

Now the company is shifting from pure research and development to the prototyping phase at its new facilities in Chicago.

Pure founder and CEO Emilie Bodoin said: “We have demonstrated that our technology is capable of eliminating some of the most energy intensive steps in anode manufacturing.”

Established by the US Environmental Protection Agency in 1996, the Green Chemistry Challenge Awards recognize chemical technologies that incorporate the principles of green chemistry into chemical design, manufacture, and use.
