Broadband benchtop NMR is a powerful tool for the quality control of battery electrolytes, it allows rapid feedback on a chemical composition of these complex mixtures. That can include analysis of solvents using1H NMR,氟化盐和稳定剂19.f nmr,31.P和11.b分析那些相同的盐以及7.李和23.Na to understand the properties of cation species in solution. In this application note we use a combination of1H and19.F NMR快速诊断观察到的两种商用锂离子电池电解质之间观察到的细胞性能差异。发现这种性能差异是由公知的水解反应产生的电解质降解的结果。19.然后在类似的电解质上使用F NMR反应监测,以了解降解反应的竞争动力学,允许更完全了解这一过程,这可能导致更好的稳定未来电解质的方法。最后,脉冲场梯度NMR用于测量“良好”和降解电解质的物理性质的可观察差异。
