Production of graphene/reduced graphene oxide from end-of-life lithium-ion batteries from electric or hybrid vehicles
Abstract
CIEMAT and CSIC have developed a procedure that enables the recovery of graphite with sufficient purity to produce graphene and reduced graphene oxide from the black mass of end-of-life lithium-ion batteries from electric or hybrid vehicles. This procedure can be applied in various industrial sectors related to urban waste management, such as the manufacturing of hybrid and electric vehicle
What problems does it solve?
End-of-life lithium-ion batteries from electric or hybrid vehicles contain graphite, heavy metals (Ni, Co, Mn, Li, Cu, etc.), and degraded electrolytes.
Currently, black mass is very difficult and expensive to recycle. Many existing processes focus solely on recovering these metals-some of which, like lithium, are not very abundant-for reuse in the production of new batteries, while graphite is often discarded and ends up as a polluting waste
Benefits
• Recovery and recovery of graphite present in the black mass of lithium-ion batteries, contributing to the circular economy and the safe and efficient recycling of waste.
• Minimizes the discharge of heavy metal materials into the environment
Potential customers
This invention offers the possibility of obtaining graphene/reduced graphene oxide from waste batteries which can be used in multiple industrial sectors related to the energy transition, electronics, automotive and biotechnology.
