[Analysis Case] Evaluation of Fluoride Ion Concentration in Lithium-Ion Battery Electrolyte

Quantitative analysis of fluoride ions can be performed using NMR.

Lithium hexafluorophosphate (LiPF6), the main component of the electrolyte in lithium-ion batteries, is known to undergo hydrolysis upon reaction with moisture, generating fluoride ions. This document presents a case where the concentration of fluoride ions produced by the atmospheric exposure of the electrolyte (1M LiPF6, EC:EMC = 3:7 v/v) was evaluated using 19F-NMR, which allows for absolute quantification without the use of standard compounds. Measurement method: NMR Product field: Secondary batteries and electronic components Analysis purpose: Failure analysis, defect analysis, degradation investigation For more details, please download the document or contact us.
