1.0M NaClO4 in EC/PC=1:1 (v/v) with 5% FEC Sodium Battery Electrolyte (KLD-NC07)

This electrolyte formulation, designated as KLD-NC07, is developed for sodium-ion battery research and contains 1.0 M NaClO₄ dissolved in a 1:1 volume ratio of ethylene carbonate (EC) and propylene carbonate (PC), with 5% fluoroethylene carbonate (FEC) as an additive. The combination of carbonate solvents provides a balanced dielectric constant and low viscosity for efficient ion transport, while the FEC additive enhances stability at the electrode–electrolyte interface, particularly improving cycling performance and suppressing side reactions. This electrolyte is commonly used in coin-cell or pouch-cell assembly for evaluating sodium-based cathode and anode materials, offering a reliable baseline for electrochemical characterization. Available in multiple mass options, it supports both small-scale screening and extended test series.
