Binder
CNP Solutions has differentiated conductive polymer synthesis and binder fabrication technology.

Conventional Binders: CNPS Binders

Conductivity

Using an electrically conductive polymers, electrode active material particles are designed to be connected through the polymeric binder even when the gap between the particles becomes longer larger.
The electrically conductive polymer binder provides excellent electrical connection between active material particles, resulting in an excellent electrical conduction through electrode layer.
Binding property

Binder molecules are designed to reduce dimensional change during charging and discharging processes
Adhesive property

Excellent adhesion of electrodes to current collector

CNP SOLUTIONS Binders

CNP Solution developed 2 types of binder systems – for wet and dry systems– both improve adhesion between active materials,
ease of processing and increased electrical conductivity, enabling battery performance such as improved capacity retention and fast charging.
The dry-system without solvents surely contributes to the reduction of carbon footprint.

Binder for Wet-system

CNP Solutions’ wet binder system maximizes integration between active material particles,
hence improving adhesion and electrical conductivity.
