Lithium-ion battery coated negative electrode rolls are negative electrode sheets formed by coating negative electrode slurry onto copper foil current collectors, drying the slurry, and then winding it up.

Lithium battery coated positive electrode rolls typically refer to the positive electrode material formed by uniformly coating the positive electrode slurry onto the surface of the current collector aluminum foil, drying, and then winding it up.

Aluminum foil for lithium batteries is an important material for the positive electrode current collector of lithium-ion batteries, directly affecting the battery's conductivity, processing, and performance.

Lithium-battery copper foil is an ultra-thin copper material used for the anodes of lithium-ion batteries.

Deionized water, or DI water for short, refers to water obtained by removing ionic impurities from water through a specific process. Common preparation methods include reverse osmosis, ion exchange, electro-deionization, and polishing mixed bed.

The primary uses of NMP are to dissolve the binder, disperse the cathode material, and facilitate the formation of a slurry suitable for coating.

Sodium carboxymethyl cellulose—commonly referred to in the industry simply as carboxymethyl cellulose and abbreviated as CMC—is a water-soluble polymer derived from natural cellulose through chemical modification.

Polyvinylidene fluoride, abbreviated as PVDF, is a fluorinated polymer. It is produced through the polymerization of vinylidene fluoride monomers and exhibits excellent chemical corrosion resistance, high-temperature resistance, electrical insulation properties, and mechanical strength.

As lithium battery technology continues to advance, many materials that are unfamiliar to the average person actually play a crucial role. Carbon nanotubes are one of them.

Conductive carbon black is usually added to the positive electrode as a conductive agent. Its core function is to build electron transport channels between active material particles and between the active material and the current collector.

Silicon-based anode materials are a type of anode materials that use silicon as the active material for lithium storage to replace or partially replace graphite.

Graphite anode material is the active material used at the end of a lithium-ion battery where lithium ions are released and electrons flow out during discharge.
