Grade: Battery Grade
Brand: Xnergy

Product Introduction

Succinonitrile (SN) is a bifunctional nitrile compound that has emerged as a key additive in both liquid and quasi-solid electrolyte systems. Its two cyano (CN) groups coordinate strongly with lithium ions, competing with solvent molecules in the Li⁺ solvation shell. This solvation-shell restructuring increases the lithium transference number, widening the electrochemical stability window and reducing anion mobility. In gel polymer and solid-state electrolyte matrices, SN serves as a plasticizer and conductivity enhancer. Xnergy supplies battery-grade SN for advanced electrolyte research across liquid, gel, and solid-state platforms.

Key Features

• Dual CN coordination — both nitrile groups actively solvate Li⁺, modifying the solvation structure and increasing transference number
• Wide electrochemical stability window — stable against oxidation at cathode potentials up to ~5 V vs. Li/Li⁺, enabling high-voltage electrolyte applications
• Solid-state electrolyte compatible — functions as both a plasticizer and ionic conductor in PEO-based and other polymer matrices
• Cathode protection — nitrile-derived CEI film stabilizes NCM cathode surfaces at elevated charge voltages
• Purity ≥99% / H₂O ≤10 ppm — battery-grade specifications for research reproducibility
• Flexible volumes — available from 1 kg lab pack to larger quantities for formulation development
