ZEON Binders

Anode Binder (Water-based)

In response to the market requirements for higher capacity of lithium ion batteries, R&D activities are accelerating on higher densification of anode and use of Si materials. With enhanced tensile strength in electrolyte, Zeon’s new binder suppresses electrode expansion over charge-discharge cycles and contributes to longer life of lithium ion batteries.

Materials for Functional Layer

With the needs for higher capacity and use in automotive applications, the safety of lithium ion batteries is becoming more and more important. Heat resistant layers of ceramic particles on separators or on electrodes to suppress short circuit current are now in practical use. Zeon started development of materials for such needs, and succeeded in commercialization of binder for heat resistant layer in 2005. Since then, rapid expansion of markets has led to wider use of Zeon’s binder.
