Quality control of lithium-ion battery electrolytes using LC/MS

The efficiency and longevity of lithium-ion batteries are largely dependent on the quality of the electrolyte. All electrolyte constituents of most lithium-ion batteries used today are sensitive to degradation caused by reaction with water. In this application note from Agilent Technologies, explore an HPLC-MS method to separate and quantify frequently used electrolyte solvents and some of their degradation products. Furthermore, discover how despite strong sample solvent, no peak distortion was noted when using the Agilent 1260 Infinity II Hybrid Multisampler in Feed injection mode.
