Novel Quantification Method for Lithium Ion Battery Electrolyte Solvents in Aqueous Recycling Samples Using Solid-Phase Extraction/Gas Chromatography-Flame Ionization Detection

Abstract

Recycling Lithium Ion Battery Electrolyte Solvents

Schematic workflow for the developed solid-phase extraction/gas chromatography-flame ionization detection providing a robust quantification of low concentrated organic carbonates in aqueous (e.g., process water from the recycling of lithium ion batteries) samples. The increased affinity toward the stationary phase allows preconcentration factors >250 for the linear and oligomeric carbonates and an effective removal of the conducting salt.
