GC/MS Analysis of Fluorophosphates as Decomposition Products in Lithium Battery Electrolyte

User Benefits

- A routine and fast GC/MS methodfordetectionofLIB decompositionproducts. - Monitoring of the LIB electrolyte after manufacturing, storage and transport. - Fluorophosphates can be considered as markers for a started electrolyte decomposition.

Introduction

The electrolyte solution is a crucial part of a typical Lithium-ion battery, consisting Li salt (f.e. LiPF6), organic carbonates and additives to ensure a stable transport of Li ions during charging and discharging processes. A significant part of battery aging can be considered as a result of the decomposition of the electrolyte. At the end of this chemical and electrochemical processes oligomeric organic compounds and organophosphates could be detected. Especially fluor containing organophosphates are of interest due to their potential neurotoxicity.
