Graphite-based anode active materials are high-performance powdered carbon materials,featuring high capacity, high tap density, long cycle life, and outstanding stability.

By leveraging the high specific capacity of silicon, these materials boost battery energy density. The buffering effect of silicon oxides, combined with the conductive and flexible networks of carbon materials, effectively mitigates the volume expansion of silicon during charge/discharge cycling, and improves electrode structural stability and cycle life.

Carbon black has a large specific surface area and excellent ion and electron conductivity, which facilitates electrolyte adsorption and enhances ionic conductivity. It is suitable for the research and production of dry batteries, lithium batteries, carbon-zinc batteries, double-layer capacitors, fuel cells, and other electrochemical systems.

Owing to their ultra‑small dimensions and excellent conductivity, carbon nanotubes serve as a highly‑effective conductive additive widely used in consumer electronics, communications, energy‑storage systems and power batteries.

PVDF offers excellent adhesion, chemical stability, thermal stability, electrical insulation, high mechanical strength, low moisture pickup and a wide processing window. It ensures a dense and robust electrode structure, withstands high temperatures and resists electrolyte attack and supports long‑term battery reliability.

The CMC negative electrode binder is a water-soluble polyanionic compound obtained by chemically modifying natural fibers. It is highly soluble in water and possesses excellent dispersion, thickening, film-forming, and water-retaining properties, which assist in the adhesion of lithium battery negative electrode materials.

The positive electrode solvent N-methylpyrrolidone (NMP) is an efficient and selective chemical solvent. It has good chemical stability and thermal stability, low volatility, and is soluble in various organic solvents such as ethanol, acetone, esters, and aromatic hydrocarbons. It also possesses the advantages of high boiling point, non-flammability, safe usage, and suitability for multiple formulation applications. It is suitable for the research and production of lithium-ion battery positive electrodes and the preparation of carbon nanotube (CNT) conductive pastes, among other fields.

Deionized water serves as the solvent for dissolving water-based adhesives such as CMC/SBR. In the preparation of the negative electrode of lithium metal batteries, by dissolving the adhesives, the strong adhesion between the negative electrode components (lithium metal/lithium-based materials, conductive agents) and the current collector can be achieved. By regulating the slurry, the uniformity of coating and the quality of electrode formation can be ensured. After drying, the porous structure formed can buffer the volume expansion of lithium metal and meet the requirements for electrolyte infiltration/filling, which is a key process medium for the stability of the lithium battery negative electrode structure and the long-term electrochemical performance of the battery.
