Characteristics 
This high conductive binder has a specific funtion performing remarkably refraining a grain boundary onsurface of active materials.In a typical application, high Nickel content of Active material such as NCM811 isoriginally suffered Oxiding deterioration upper 4.0Voltage range. Our recommending binder could solve thissubject by coating a conductive polymer layer on the surface to protect such oxidization in the Celloperation.  In addition, this high conductivity bainder is also feasible for recipe with Solid State Electrolytein SSE battery field.


Conductive Adhesives for Cathode and Anode electrodes

丂CB Series丂丂丂Summary
This is composed by Polyvinylidene fluoride polymerized with Ionic Liquid.
It is available to make electrodes having an ideal conductive network with
strong enough in bonding and elastic adhesive properties to obtain a close-
packed structure by a proper mixing with conductive agents.

Characteristics of CB Binder
丂丂丂丂1.丂CB binder support improving IR drop property through forming Closed Pack structure of Electrodes layer.
丂丂丂丂2.丂Standard dosage in use of CB binder is to reduce by one third volume of Conductive agent and the balance of the
             predetermined total recipe 倱hould be added with active agent which means contributing an improvement of
             Volumetric Energy Density.
丂丂丂丂3.丂CB binder performs superior low temperature property to that of conventional PVdF binder.
丂丂丂丂4.丂A bonding part of each particle is formed at point by point to improve electrode density and also its parts are elastic
             property suitable for absorbing to some degree against swelling and shrinking property of Silicone and even graphite
             active materials as well as possible to increase a press density of electrode at least more 10 to 20 % than that of
             conventional PVdF.
