Samsung introduces Circular Battery Supply Chain with Galaxy S25

Samsung has taken a significant step towards reducing the environmental impact of electronics with the launch of its Galaxy S25 series. Unlike the Galaxy S24, which relied on cobalt from recycling companies, the Galaxy S25 features 50% recycled cobalt sourced from previously used Galaxy batteries.

To achieve this, Samsung established a Circular Battery Supply Chain, a multi-phase process designed to extract cobalt from old batteries for reuse in the Galaxy S25’s lithium-ion batteries.

The process starts by collecting old Galaxy smartphones through trade-in programs or special battery collection bins. These devices are then shredded into a “black mass,” from which cobalt is extracted.

The recycled cobalt is processed to produce cathode components, enhancing thermal stability and reducing overheating risks. Samsung states that cobalt makes up 25% of the battery’s weight, meaning 12.5% of the entire battery cell in the Galaxy S25 is made from recycled materials.

Cobalt is a critical component for smartphone batteries but comes with challenges such as high costs, scarcity, and ethical concerns related to mining practices. Samsung’s innovative approach helps reduce dependence on newly mined cobalt, addressing both environmental and ethical issues.

With this initiative, Samsung is setting an example in sustainable technology, showcasing how innovation can align with environmental responsibility.
