Batteries are very common in our daily life, and the application of many items requires the participation of batteries. In the production of batteries, manufacturers usually add sodium carboxymethyl cellulose to them to improve the quality and performance of batteries.
1、 Characteristics of battery grade sodium carboxymethyl cellulose
1. Sodium carboxymethyl cellulose is a product used in an aqueous system. The negative electrode material is mainly adhesive, which has been widely used in the field of battery manufacturing at home and abroad. Suitable adhesive doses may be relatively large battery capacity, cycle life, and relatively low internal resistance. CMC-Na can make the product hydrophilic and soluble, completely soluble in water, without free fibers and impurities.
2. Uniform degree of substitution and stable viscosity can provide stable viscosity and adhesion.
3. High purity products are produced and have a low metal ion content.
4. The product has good compatibility when used with SBR latex and other materials.
2、 Sodium carboxymethyl cellulose as a cell adhesion agent
1. Adhesion and protection of active substances.
2. The electrode structure is stable.
3. Prevent the precipitation of active substances.
4. Improve charging and discharging performance.
It is known that in the production of batteries, adding sodium carboxymethyl cellulose according to its regulations can effectively improve the performance and service life of batteries. At the same time, CMC-Na is favored by many enterprises due to its own product characteristics.
