Carboxymethyl Cellulose Sodium
Carboxymethyl Cellulose Sodium, Carboxymethyl Cellulose, shortly CMC, used as additive in different field,CMC has the fuctions of thickening ,suspending,emulsifying, stabilizing ,shaping, filming,bulking, etc. It can replace the application of guar gum,gelatin and pectin.It is widely used in modern industry,such as food, ceratic,paper making, toothpaste , coating etc.
Dynacel® Battery Grade CMC with the strong cohesion, good heat stability, electrical conductivity and electrochemistry property, makes the active substance and electrolyte form the even and dispersive paste, and takes the hydrogen bond effect with the silicon, therefore, it is not only widely used as the binder of cathode and anode, gel for cathode protection, but also widely applied in the silicon base electrode and graphite modification.

Application
Binder has the great impact on the electrode property of the battery. Appropriate binder can effectively change the general performance of the electrode, and make the active substance, conductive agent and current collector contact evenly, and enhance the completeness of the electrode. As the binder, CMC can be widely applied in the kinds of electrode material such as lithium battery, natural graphite, mcmb, lithium titanate, tin-based, silicon-based negative electrode material and iron-phosphate-based lithium cathode material etc. It greatly enhances the battery capacity, circulation stability and lifespan circulation.
Dosage: 50mg/kg-200mg/kg
