1． Lithium ion secondary batteries

Market of lithium ion secondary batteries had been increasing drastically, and our CMC had been used for anode of lithium ion battery.

Production process of anode

Making carbon paste by mixing anode material (carbon), water, binder (SBR, and CMC). Apply this carbon paste onto copper film and make anode.

Function of CMC in carbon paste are “thickener ”, “stabilizer”, “plasticizer”.

2． Surface treatment of electrolytic copper foil

In production process of electrolytic copper foil, by adding CMC to electrolytic solution, surface of copper foil can be controlled properly.

3.Carboxymethyl cellulose sodium salt as a cell adhesive role:

1. bonding and protection active substances

2. the pole piece structure stable

3. to prevent the precipitation of the active substanc

4. to improve the charge-discharge performance
