The raw materials for new energy batteries include various chemical substances, with the main components typically involving the different parts of the battery. Here are the main raw materials for general new energy batteries:

Positive electrode materials

  • Three-element materials (NCM/NCA): Including Lithium Nickel Manganese Oxide (NCM) and Lithium Nickel Cobalt Oxide (NCA), containing nickel, cobalt, manganese, and other elements.

  • Lithium Iron Phosphate (LFP): Comprising iron, phosphate, and other compounds.

Electrolyte

  • Polymer electrolyte: Commonly used in lithium polymer batteries.

  • Liquid electrolyte: Contains organic solvents that dissolve lithium salts and is used in liquid batteries.

Battery housing

  • Aluminum (for the positive electrode) and copper (for the negative electrode): Used for the battery casing and the conductive layer.

Negative electrode materials

  • Graphite: Used in conventional lithium-ion batteries, including natural graphite and artificial graphite.

Separator

  • Polymer separator: Used to separate the positive and negative electrodes and ensure the proper operation of the battery.

Electrolyte components

  • Lithium salt: Usually hexafluorophosphoric acid lithium (LiPF6) and others.

  • Solvents: Carbonates are commonly used.

Battery precursors are crucial materials in the manufacturing of batteries in the field of new energy. Here are some of the key battery precursors and their uses:

MnSO4·H2O

Manganese sulphate monohydrate in battery quality

Use: Manganese sulfate monohydrate is commonly used in cathode materials for alkaline batteries. It serves as a raw material for the production of manganese oxide, which is then used in the positive electrodes of batteries.

Li2CO3

Lithium carbonate

Use: Lithium carbonate is a key component in the production of cathode materials for lithium-ion batteries. It plays a central role in providing lithium ions that migrate between the anode and cathode during the charging and discharging process.

FeSO4·7H2O

Iron(II) sulfate heptahydrate in battery quality

Use: Ferrous sulfate heptahydrate can be used in the production of electrode materials for rechargeable lithium iron phosphate batteries (LiFePO4). LiFePO4 is a commonly used cathode material with excellent performance characteristics, including safety and stability.
