Natural graphite generally uses natural flake graphite as raw material, which is modified to make spherical natural graphite for use.

Natural anode materials for lithium-ion batteries refer to minerals or biomass-derived substances used as negative electrodes, characterized by:

• Natural Resource Base (minimal processing from natural sources),
• Low Carbon Footprint (reduced energy-intensive steps like graphitization),
• Cost Competitiveness (lower raw material and manufacturing expenses).
