Are lithium-ion batteries a threat to the environment?
With the emergence of portable electronics and electric vehicle adoption, the last decade has witnessed an increasing fabrication of lithium-ion batteries (LIBs). The future development of LIBs is threatened by the limited reserves of virgin materials, while the inadequate management of spent batteries endangers environmental and human health.
Thus, one million waste batteries would contain around 25,000 tonnes and 50,000 m 3 of unprocessed spent graphite when the proportion of graphite in each battery pack is roughly calculated as 10%. Consequently, from economic and environmental point of view, spent graphite must be recycled.
What contaminants are found in graphite?
Contaminants on the spent graphite surface include residual LiF at the interface of the solid electrolyte, polyvinylidene fluoride binder, and LiPF 6 electrolyte. The remaining lithium (Li 2 CO 3) and CuO invade the crystal structure of graphite.
Can graphite anodes be recycled for lithium ion batteries?

Can graphite be used as a negative electrode material?
Future research efforts on practical engineering application are proposed. With the explosive growth of spent lithium-ion batteries (LIBs), the effective recycling of graphite as a key negative electrode material has become economically attractive and environmentally significant.
How does graphite impact the environment?
With values ranging from 0.53 to 9.76 kg·CO 2 equiv. per 1 kg of graphite, energy consumption and waste acid generation are the main environmental drivers. A sensitivity analysis demonstrates a 20–73% impact reduction by limiting to one-fourth the amount of H 2 SO 4.
