Graphite is a significant player in the battery sector, with demand expected to grow from 165,000 tonnes in 2018 to almost 1 million tonnes by 2030. Natural and synthetic graphite compete in the battery anode materials market, and the split of demand was around 50:50 in 2018.
Synthetic graphite production is a significant source of NOx, SOx, and particulate emissions. While most of the carbon contained remains in the product during processing, generating relatively low CO2 emissions, the burning off of sulfur, nitrogen, and ash impurities from its hydrocarbon feedstocks contributes to these pollutants.
According to Minviro, most published LCA studies for graphite production do not sufficiently represent the sizable contribution of different electricity scenarios to the overall impact of operations. “Producing anode grade graphite for lithium-ion batteries (LIBs) is energy-intensive.
Pollution from graphite mining in China has resulted in reports of “ graphite rain ”, which is significantly impacting local air and water quality. The production of green technologies creates many interesting contradictions between environmental benefits at the point of use, versus human and environmental costs at the production end.
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.
Research has shown that natural graphite mining can cause dust emissions. 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.

Battery-grade synthetic graphite is made from oil feedstock. Producing 1 kilogram in China produces about 17 kilograms of CO2e, according to the latest data collected by Minviro. Making 1 kilogram of natural graphite in China — a mined form of the material — produces approximately 16.8 kilograms of CO2e.. Lithium, another major battery ingredient, produces …
It depends exactly where and how the battery is made—but when it comes to clean technologies like electric cars and solar power, even the dirtiest batteries emit less CO2 than using no battery at all.

Localising battery production is not merely about reducing dependency; it is also a significant economic opportunity. As the fourth-largest automobile manufacturer globally, India''s transition from internal combustion engines to EVs could create jobs, boost GDP, and enhance the country''s global competitiveness.
Speculation arose that graphite could be in short supply because a large EV battery requires about 25kg (55 lb) of graphite for the Li-ion anode. Although price and consumption has been lackluster, there are indications that the demand is tightening. China is the main producer of anode material. Figure 1: Natural Graphite Production (2023)
Industrial scale primary data related to the production of battery materials lacks transparency and remains scarce in general. In particular, life cycle inventory datasets related to the extraction, refining and coating of graphite as anode material for lithium-ion batteries are incomplete, out of date and hardly representative for today''s battery applications.
EV Battery Makers Are Grappling with Graphite Graphite is used for the negative end of a lithium-ion battery, known as the anode. Currently, 85% of graphite comes from China. A rival to naturally ...
The lithium ion battery industry is expected to grow from 100 gigawatt hours of annual production in 2017 to almost 800 gigawatt hours in 2027. Part of that phenomenal demand increase dates back to 2015 when the Chinese government announced a huge push towards electric vehicles in its 13th Five Year Plan. The battery of a Tesla Model S, for example, has …
