三电极配置允许对反应机理进行有针对性的研究,包括新兴钠离子电池电极材料中的电荷存储和相间形成。然而,使用金属钠作为参比电极会导致在酯基电解液中自发形成电活性的可溶性分解产物。这些电解液分解产物在碳电极上进行氧化,其电位可能被误认为是可逆钠(De)嵌入,从而掩盖了材料性质的真实测量。
Three-electrode configurations allow targeted studies of reaction mechanisms, including charge storage in and interphase formation on electrode materials for emerging sodium-ion batteries. However, using sodium metal as a reference electrode results in spontaneous formation of electroactive soluble decomposition products in an ester-based electrolyte. These electrolyte decomposition products undergo oxidation at carbon electrodes at potentials that can be mistaken for reversible sodium (de)intercalation, thus obscuring true measurements of material properties.
