A team of researchers from the Department of Chemical Engineering at Pennsylvania State University (Penn State, U.S.A) has reengineered the makeup of solid-state lithium-ion (SSLiBs) batteries so that their components are completely recyclable.
Solid-state batteries and recycling hurdles
Unlike conventional lithium-ion batteries, SSLiBs use a solid electrolyte instead of a liquid electrolyte. Solid electrolytes are non-flammable and less hazardous than liquid electrolytes which incur a risk of fire and explosion if exposed to extremes in temperature. Solid-state batteries can hold more power in the same volume, resulting in a longer battery life. Furthermore, they have an extended lifespan and improved long-term stability.
SSLiBs use solid electrolytes containing strong ceramics and unique chemical constituents, which might represent distinct environmental risks if not properly treated. Their intricately connected layers make deconstruction difficult while preserving recyclable components. Furthermore, recycling these types of batteries is more costly than recycling normal lithium-ion batteries since it requires specialized equipment and techniques.
