Design Principles

"Design for Disassembly and Material Recovery"

As the demand for lithium-ion batteries grows, so does the volume of end-of-life batteries. Developing efficient and sustainable recycling processes is crucial for resource conservation and mitigating environmental hazards. Direct recycling offers a promising pathway to a circular economy for battery materials.
