1.0M NaClO4 in EC/PC=1:1 (v/v) with 2% FEC Sodium Battery Electrolyte (KLD-NC20)

This sodium electrolyte, designated KLD-NC20, is formulated for research applications in sodium-ion battery systems. It contains 1.0 M sodium perchlorate (NaClO₄) dissolved in a 1:1 volume ratio of ethylene carbonate (EC) and propylene carbonate (PC), with a 2% fluoroethylene carbonate (FEC) additive. The addition of FEC is intended to improve electrode–electrolyte interfacial stability and cycling performance in sodium-based cells. As a pre-mixed, ready-to-use electrolyte, it supports fundamental studies on sodium storage mechanisms and the evaluation of electrode materials such as hard carbon, layered oxides, or Prussian blue analogues. The product is available in several quantities suitable for laboratory-scale testing, from 50 g up to 1 kg. This formulation is typically employed in coin-cell or pouch-cell assembly for electrochemical characterization, including cyclic voltammetry, rate capability, and long-term cycling tests in sodium battery research.
