Latest Patents

Teufl’s patent, “Method for Recycling a Solid Electrolyte and Cathode Material from Solid-State Lithium Batteries,” describes a process for separating and recovering battery components. First, the battery is separated into a solid mixture containing lithium anode, cathode material, and solid electrolyte components. An aprotic solvent is then used to dissolve the solid electrolyte, allowing the solution to be separated from insoluble constituents.

Next, the insoluble constituents are treated with a protic solvent to dissolve lithium salt while leaving the cathode material undissolved. After the lithium salt solution is separated, the recovered cathode material is calcined with an added lithium compound. The process is designed to recover both solid electrolyte and cathode material through successive separation and treatment steps.

Career Highlights

Teufl’s listed invention focuses on a technical challenge in battery recycling: recovering distinct materials from a solid-state battery mixture. The method’s staged use of aprotic and protic solvents separates the electrolyte, lithium salt, and cathode material for further processing.
