4. Graphite Sources

Graphite is essential for anode production in lithium-ion batteries.

• Natural Graphite: The primary source of natural graphite comes from mines located in China, Brazil, Canada, and Mozambique. Natural graphite is preferred for its electrical conductivity.
• Synthetic Graphite: In addition to natural sources, synthetic graphite can be produced from petroleum coke through high-temperature processes. This method allows for greater control over purity and particle size.

5. Environmental Considerations

The extraction of raw materials for lithium batteries raises several environmental concerns:

• Water Usage: Brine extraction can lead to significant water depletion in arid regions, impacting local ecosystems and communities.
• Mining Impact: Hard rock mining can result in habitat destruction and pollution if not managed responsibly.
