Product Introduction

Fluorobenzene (FB) is a low-viscosity, electrochemically inert aromatic diluent that has become a key component in localized high-concentration electrolyte (LHCE) formulations. Unlike conventional solvents, FB neither solvates lithium salts nor participates in electrode reactions at typical battery potentials — making it a chemically “invisible” diluent. When added to high-concentration electrolytes (HCE, typically 3–5 M), FB reduces viscosity and cost without disrupting the tight Li⁺–anion solvation clusters responsible for HCE’s unique SEI chemistry. The result is an LHCE that combines HCE-level performance with practical processability, and has demonstrated excellent results in Li-metal and high-voltage cathode systems. Xnergy supplies battery-grade FB for LHCE research and advanced electrolyte development.

Key Features

• Electrochemically inert diluent — does not participate in anode or cathode reactions; preserves the solvation structure of the concentrated salt solution
• Enables LHCE formulation — dilutes HCE viscosity while maintaining the Li⁺–anion aggregates that drive favorable SEI chemistry
• Low viscosity — dramatically reduces solution viscosity of 3–5 M LiFSI/DME or LiFSI/carbonate electrolytes
• Fluorinated for stability — C–F bond stability prevents oxidative decomposition at high cathode potentials
• Purity ≥99% / H₂O ≤10 ppm — battery-grade control essential for moisture-sensitive concentrated electrolytes
• Flexible volumes — available from 1 kg for lab-scale to larger quantities for cell-scale LHCE batches
