Toynol® ET-206 Dispersant for Conductive Materials
Toynol® ET-206 Dispersant for Conductive Materials in Waterborne Systems
Abstract
Toynol® ET-206 is a high-efficiency phosphate ester salt dispersant developed to solve the dispersion stability problems of conductive materials (such as conductive carbon black, carbon nanotubes, and graphene) and lithium battery anode slurries in waterborne systems. Its core functions are significantly reducing dispersion system viscosity, improving material conductivity, and improving dispersion stability. Compared with conventional approaches, it offers excellent electrochemical stability (0.1 V-4.8 V vs. Li/Li), high dispersion efficiency, and is APEO-free, making it a suitable option for new energy materials such as lithium-ion battery anode slurries and waterborne conductive coatings.

Frequently Asked Questions
Q: Does ET-206 differ in dispersion performance for different types of conductive materials (such as carbon black and carbon nanotubes)?
A: Yes. ET-206 shows different dispersion performance for different conductive materials. For conductive carbon black, a dosage of 15%-30% is recommended; for harder-to-disperse materials such as carbon nanotubes, the dosage can be increased to 30%-50%, to be optimized through testing.
Q: In lithium battery anode slurry, how does the ET-206 dosage affect battery performance?
A: An appropriate dosage improves slurry uniformity and electrode conductivity, but excessive dosage may affect binder performance. It is recommended to determine the optimum dosage through dosage screening, generally controlled within 0.5%-3.0% of the active material weight.
Q: Can this product be combined with other additives?
A: Yes. ET-206 is highly compatible with most waterborne system additives, but it is recommended to add in sequence: dispersant first, then other functional additives, with a compatibility test.
Q: What is the significance of the product’s electrochemical stability (0.1 V-4.8 V) for battery applications?
A: This property ensures ET-206 remains stable within the lithium battery operating voltage range without decomposing into side reactions, which benefits battery cycle life and safety.
