Key Battery Materials

Battery materials refer to the various materials needed to manufacture batteries, mainly including anode materials, cathode materials, binders, electrolyte materials, separators, etc.

• Graphite. Graphite is the most commonly used anode material in lithium-ion batteries due to its good electrical conductivity and capacity.
• Lithium titanate (LTO). LTO is used in specific applications for its long cycle life and excellent safety, though it has a lower energy density compared to graphite.
• Silicon-based materials. Silicon-based materials provide a higher capacity than graphite, but suffer from significant volume expansion and contraction during charging and discharging, leading to mechanical degradation.

• Lithium iron phosphate (LiFePO₄). Known for its stability and safety, LiFePO₄ is commonly used in larger applications like electric vehicles and grid storage, despite having a lower energy density.
• Lithium nickel manganese cobalt oxide (NMC). NMC balances energy density, longevity, and safety, making it popular in electric vehicles and portable power tools.
• Lithium nickel cobalt aluminum oxide (NCA). NCA is mainly used in electric vehicles due to its high energy density and long cycle life.

• Polyvinylidene fluoride (PVDF). PVDF is a widely used binder in batteries, which has good chemical stability and bonding properties.
• Carboxymethyl cellulose (CMC). CMC is a water-soluble binder that is mainly used with other materials, especially in sodium-ion and lithium-ion batteries.
• Styrene-butadiene rubber (SBR). SBR is often combined with CMC for better mechanical properties. It can improve the flexibility and adhesion of active materials.

• Liquid electrolytes. Liquid electrolytes are usually composed of lithium salts dissolved in organic solvents. They are widely used in commercial lithium-ion batteries.
• Solid electrolytes. Solid electrolytes are known for their potential in all-solid-state batteries, offering excellent safety and stability.
• Gel electrolytes. Gel electrolytes are a hybrid between liquid and solid electrolytes, providing good mechanical properties and ionic conductivity.

• Polyethylene (PE) and polypropylene (PP). PE and PP are commonly used polymers in separator membranes due to their good chemical stability and mechanical strength.
• Ceramic-coated separators. Ceramic-coated separators provide enhanced thermal stability and safety characteristics.
