Qingdao Linguang Biochemical Co., Ltd is a professional high-tech enterprise which was established in 2010.
We engage in the development, manufacture, sales and service of sodium carboxymethyl cellulose(CMC).
The annual output of our company reaches 20KTon and we gained the certification of ISO9001 and ISO14001 in2012.
ingdao Linguang Biochemical Co., Ltd produces cMc products with natural plant fiber as main raw material.
"LinGuang" CMC which is researched and developed independently by ourselves with the high viscosity ,
high degree of substitution and h igh penetration rate has become the well-known brand. It is widely used in food,ceramic,petroleum, paper,toothpaste,printing,medicine, detergent, etc. It is exported to Europe, United States,Southeast Asia ,Middle East and other countries.
Battery Grade CMC
Sodium carboxymethyl cellulose (CMC) has a strong binding force and good electrochemical characteristics, so it is widely used as negative paste binder. With appropriate amount of binder it can help obtain a relatively large battery capacity and more cycle life.
Application characteristics of CMC in battery:
1. Binding and active protection materials;
2. Improve the fluidity of insoluble materials in solution;
3. Prevent the precipitation of active substances and improve the dispersion stability of insoluble materials in solution;
4. Improve charging and discharging performance;
As a binder, an SBR/CMC-based polymeric binder is widely used in the secondary battery anode.
The binder for secondary battery electrodes helps to adhere well to a current collector, a thin film, by binding electrode active material and an electrical conductive material. By adding CMC, the particles of active material and conductive material can be bonded well to each other with minimal adhesion.
This increases the content of electrode active materials, reduces the content of binders, and improves the binding characteristics than PVdF systems to maximize battery capacity and energy density. Also, the SBR particles are represented in point contact unlike PVdF organic binders between the electrode active materials, which can maintain the electrochemical properties of the electrode well.
