Diethyl Carbonate(DEC),Battery Grade 500g

Diethyl Carbonate (DEC), Battery Grade 500g

Chemical Name: Diethyl Carbonate
CAS Number: 105-58-8
Product Code: EL105-58-8
Grade: Battery Grade
Brand: Xnergy

Product Introduction

Diethyl carbonate (DEC) is the higher-boiling member of the linear carbonate family, with a boiling point of 126°C compared to DMC’s 90°C. This reduced volatility makes DEC particularly useful in electrolyte formulations where minimizing solvent evaporation is important, such as elevated-temperature cycling studies or open-atmosphere cell assembly. When blended with EC, DEC yields an electrolyte with good ionic conductivity and a broader liquid operating range at elevated temperatures. Xnergy supplies DEC to battery-grade specifications with tightly controlled moisture and acid content.

Key Features

• Higher boiling point (126°C) — lower volatility than DMC and EMC, reducing solvent loss during elevated-temperature operation
• Broad liquid range — extends the upper operating temperature of EC-based electrolyte blends
• Good LiPF₆ compatibility — supports adequate salt dissolution and ionic conductivity in EC/DEC blends
• Purity ≥99% — battery-grade quality for consistent electrochemical results
• H₂O ≤10 ppm / Acid ≤10 ppm — precise control of trace contaminants
• Flexible volumes — available from 1 kg laboratory packs to bulk production orders

Specification

Application Areas

• Elevated-temperature electrolyte stability and cycling studies (45–60°C)
