About Battery raw material
Lithium-ion batteries require several critical raw materials for their core components: a lithium-based metal oxide cathode (e.g., NMC, LFP), a graphite-based anode, a separator, and a lithium-salt electrolyte. Key materials include lithium, nickel, cobalt, manganese, and copper, which are critical for high energy density and electric vehicle applications.

Core Raw Materials Breakdown
Cathode (Positive Electrode): This holds the highest cost share (
) and is typically made of lithium nickel manganese cobalt oxide (
or NMC) or lithium iron phosphate (
or LFP). It is responsible for the battery's energy density and performance.
Anode (Negative Electrode): Primarily made of graphite (natural or synthetic) due to its stability, long cycle life, and low cost. Silicon is increasingly used to improve capacity.
Electrolyte: Conducts ions between electrodes, generally consisting of a lithium saltsuch as Lithium hexafluorophosphate (
)dissolved in organic solvents (e.g., ethylene carbonate).
Separator: A thin polymer film (polyethylene or polypropylene) placed between the anode and cathode to prevent short circuits.
Current Collectors: Copper foil is used for the anode, while aluminum foil is used for the cathode.

Critical Mineral Sourcing
Lithium: Extracted from hard rock ores like spodumene or from lithium-rich brines found in salt flats.
Cobalt: Often mined as a by-product of nickel or copper mining; used to stabilize the cathode.
Nickel & Manganese: Crucial for enhancing power and energy, commonly refined for cathode production.
Graphite: Extracted as natural flake graphite or produced synthetically.
