Battery Parts Can Be Recycled Without Crushing or Melting, Saving Valuable Raw Materials
Researchers in Finland have discovered that electrodes in lithium batteries containing cobalt can be reused following a special process.
In comparison to traditional recycling, which typically extracts metals from crushed batteries by melting or dissolving them, the new process—which newly saturates the electrodes with lithium—saves valuable raw materials, and likely also energy.
The rechargeable batteries problem
The proliferation of electric cars, smartphones, and portable devices is leading to an estimated 25 percent increase globally in the manufacturing of rechargeable batteries each year.
Many raw materials used in the batteries, such as cobalt, may soon be in short supply. The European Commission is…
