Samsung has recently introduced a closed-loop battery recycling system for its flagship devices, providing detailed insights into the process. In Vietnam, Samsung’s production facilities collect around 200 tons of waste battery materials each year. While some advanced recycling systems in other countries repurpose these materials for electric vehicle batteries, Vietnam’s infrastructure currently falls short. In response, Samsung has developed a solution to ensure that these materials are efficiently utilized.
The facilities in Vietnam generate a significant volume of waste batteries, including defective units from the manufacturing process and those recovered from traded-in Galaxy phones. Youngmin Kim from Samsung’s Circular Economy Lab emphasizes the importance of recycling these resources to integrate them back into their products. The recycling process begins with the collection of old Galaxy devices. After collection, the batteries are removed, discharged, and shredded into smaller fragments.
Sangcheul Lee from the Battery Group explains that the engagement with partner companies was crucial to navigate rigorous procedures. Fire hazard prevention during transport required the batteries to be crushed, and obtaining the necessary environmental certifications was time-consuming. Next, the shredded material is processed into a fine powder known as “black mass,” from which cobalt is derived. Cobalt’s unique properties allow it to be recycled indefinitely and remain indistinguishable from newly mined cobalt in manufacturing.
This extracted cobalt is then used to create cathode materials for the batteries of the Galaxy S25. These materials are essential for ensuring the stability and performance of lithium-ion batteries as cobalt facilitates the movement of lithium within them. Ultimately, Samsung’s Circular Battery Supply Chain effectively implements the closed-loop system, successfully aligning with its environmental vision for the new Galaxy S25. Tsveta, a dedicated technology enthusiast, shares insights into how this innovative approach is transforming the tech landscape.
In summary, Samsung’s efforts reflect a commitment to sustainability through an efficient recycling process, which serves as a blueprint for the future of battery production.
