Description

Sodium Carboxymethyl Cellulose Battery Grade

Sodium Carboxymethyl Cellulose as major bond of anode material in waterborne system has been widely used in battery industry both home and in abroad. The perfect quantity of bond can achieve some advantages like lager call capacity, much cycle life and low inner resistance. With regard to this our company has effectively improved the manufacturing technique of Sodium Carboxymethyl Cellulose upon special performance and product requirements thus develop battery grade Sodium Carboxymethyl Cellulose.
