This research investigated the potential impacts of spent graphite on environmental and human health using standardized toxicity extraction and Life Cycle Impact Assessment models. The spent graphite samples were classified as hazardous waste due to the average nickel content of 337.14 mg/L according to Chinese regulations.

Efficient graphene production is critical for commercial applications. Liquid-phase exfoliation, one of the most promising methods for mass production of graphene, is limited by small size and low yield. By optimizing the fluid forces, we have achieved the size-controlled production of high-quality graphene. The bending and cleavage caused by the collision …

The purification of battery-grade anode products requires high quantities of sodium hydroxide and hydrofluoric acid, which may be harmful to both human health and the environment. Around 75,000 tonnes of graphite is required to create 1 million EVs, meaning that to produce 12 million EVs will need 900,000 tonnes of graphite by 2025.
