The Lithium-ion Batteries and Nanotechnology for Electric Vehicles Partnership, a public-private partnership of lithium-ion batter manufacturers and suppliers, recyclers, trade organizations, university scientists, and officials from the Environmental Protection Agency and the Department of Energy, released a life-cycle assessment April 30 finding that reducing the use of metals in lithium-ion batteries, incorporating recycled materials, and using a process without solvents to make them would improve their environmental profile. The report, Lithium-ion Batteries and Nanotechnology for Electric Vehicles: A Life Cycle Assessment, also encourages researchers to find ways to reduce the energy needed to make single-walled carbon nanotubes, which are being designed to be a component of Li-ion batteries.
