The CMC-Li product developed by us for the first time and applied in the lithium battery industry. Over the past 10 years, more than 10 SCI academic papers have been published and more than 20 patents have been granted. It can reduce the precipitation of lithium when CMC-Na is used as a binder, reduce the internal resistance of lithium batteries by 5%-15%, improve the first-time efficiency by 1%-2%, increase the ionic conductivity by 110%, and increase the cycle life by 1.5%-3%, etc.

Compared with other CMC-Na products in the market, our modified CMC-Na product using slurry process has the following advantages and features: 1. Natural raw materials, renewable resources, health and safety; 2. Slurry process with stable quality and stability without attenuation, resistant to acid, salt and heat; 3. Good solubility, high transparency and few gel particles; 4. Rich in variety.

CMC-NH4 is an ionic polymer material. Compared with other carboxymethyl cellulose salts, it is characterized by good cohesiveness and a small amount of residues after roasting. It is suitable for some working conditions with higher requirements or sensitivity to metal ions. Currently, it is mainly used as a denitrification catalyst, water coating powder for fluorescent lamps, and binders for ceramics, lithium batteries, etc.

PAA is applicable to silicon-based anode materials, with no solvent release, green production environment, low cost, low flammability, use safety and so on. The high-concentration carboxyl functional group of PAA can improve the performance of SEI film, and increase the initial coulomb efficiency of pure silicon electrodes to more than 90%.

SBR lithium battery is a hydrophilic and oleophilic substance. The waterborne group is combined with the surface group of the foil to form cohesive force, which contributes to dispersion and the stability of slurry. The oily chain segment is combined with the negative electrode to form cohesive force, so as to achieve the bonding effect.
