   Scientists restore dead EV batteries to 95% capacity using thermochemical treatment

   Researchers have developed a method to revive end-of-life lithium-ion batteries to 95% of their original capacity without breaking them down into raw materials. This process uses a thermochemical treatment to restore aging cells. The approach allows for the recovery of battery function without the need to dismantle components into base elements, offering a faster alternative to traditional cathode recycling methods.

   Why it matters

   Standard battery recycling often requires intensive processes to extract raw materials from spent cells. This method targets the restoration of the battery's operational state rather than material recovery. Reducing the need for raw material extraction could lower the environmental impact of EV battery disposal.

   What is confirmed

   • The new restoration method returns end-of-life lithium batteries to 95% capacity.
   • The process restores aging EV batteries without breaking them down into raw materials.
   • The restoration utilizes a thermochemical treatment.

   Still unconfirmed

   • The restoration process is based on a decades-old chemistry idea.
   • The specific restoration technique is referred to as the Cornell Method.

   What to watch next

   • Verification of the method's scalability for industrial battery fleets
   • Comparative cost analysis between thermochemical restoration and raw material recycling
   • Peer-reviewed data on the long-term stability of restored batteries
