Solar Pyrolysis: Revolutionizing Lithium Battery Recycling with Solar Energy

• French researchers at PROMES-CNRS have developed a solar-powered pyro-metallurgical process to recycle valuable elements from lithium-ion batteries, revolutionizing the recycling landscape with concentrated solar thermal energy.

French researchers at the PROMES-CNRS laboratory have developed a solar-powered pyro-metallurgical process to recycle valuable elements from lithium-ion batteries. The process, known as solar pyrolysis, uses concentrated solar thermal energy to generate a metal alloy comprising lithium, cobalt, nickel, and manganese. This marks the first successful demonstration of pyrometallurgical recycling using solar energy. The researchers envision the proliferation of smaller solar battery recycling plants across Southern Europe, taking advantage of the region's ample solar resources.

Traditionally, lithium-ion batteries have been recycled using hydrometallurgy, but the high energy consumption of pyrometallurgy has limited its use. However, the integration of concentrated solar thermal energy could revolutionize the recycling landscape. The researchers conducted a proof-of-concept test using a 1.5 kW solar furnace, successfully demonstrating the solar pyrolysis process. Future steps include refining the process, exploring reaction mechanisms, and mitigating pollutant emissions.
