Application

Optimized for wet processing applications, butyl butyrate helps in the preparation of slurries where active materials, binders, and conductive additives are homogenously dispersed. Its compatibility with argyrodite electrolytes makes it a preferred choice when fabricating advanced solid electrolyte electrodes under inert atmospheres, ensuring minimal contamination and consistent electrochemical performance. This solvent’s well-defined physical properties and low impurity profile facilitate reproducible processing conditions, enabling reliable production of high-performance battery components.

Features and Benefits

  • High Purity: Maintains an uncontaminated environment for sensitive solid electrolyte processing.

  • Excellent compatibility, low viscosity and optimal boiling point ensure uniform slurry processing for reliable electrode fabrication.

General description

Our butyl butyrate (≥99% assay, anhydrous, low trace metals) is a high-purity solvent tailored for battery solid electrolyte processing. Its exceptional chemical purity and low water and trace metal levels ensure reliable performance in sensitive applications such as slurry processing of solid electrolytes, particularly those based on argyrodite systems. With a boiling point of 164–165 °C and a viscosity of 0.73 cP, butyl butyrate provides excellent solvent characteristics that promote uniform coating, ultimately contributing to high-quality electrode fabrication.
Butyl butyrate is a biodegradable solvent used in green chemistry and sustainable manufacturing processes. Its low toxicity and renewable origin make it an eco-friendly alternative in battery electrolyte formulations and other chemical applications, supporting greener technologies by reducing environmental impact and promoting safer, sustainable production.
