Lithium-ion batteries contain several key chemical components, depending on their type. Here are some of the most common chemicals and chemistries used:
- Cathode Materials:
- Lithium Cobalt Oxide (LiCoO2): Commonly used in portable electronics like smartphones and laptops due to its high specific energy.
- Lithium Nickel Manganese Cobalt Oxide (NMC): Frequently used in electric vehicles and power tools for its high energy density and performance.
- Lithium Iron Phosphate (LiFePO4): Known for safety and stability, often used in industrial applications and some electric vehicles.
- Lithium Manganese Oxide (LMO): Utilized for its thermal stability and cost-effectiveness.
- Lithium Nickel Cobalt Aluminum Oxide (NCA): Offers high energy density and is used in electric vehicles.
- Anode Materials:
- Graphite: The most common anode material, providing a high capacity for intercalating lithium ions.
- Electrolytes:
- Lithium Hexafluorophosphate (LiPF6): Commonly dissolved in organic carbonates like ethylene carbonate and diethyl carbonate.
- Other Components:
- Separators: Typically made from polyethylene or polypropylene to prevent electrical shorts.
- Housing and Contacts: Materials like copper and aluminum are used for electrical connections and structural integrity.
