Introduction

In recent years, lithium-ion batteries have rapidly gained traction in fields, including electric vehicles and portable electronic devices, owing to high energy density and long lifespan. This widespread adoption is largely driven by increasing demand for sustainable energy solutions and advancements in technology. The performance of lithium-ion batteries is significantly influenced by the composition and purity of carbonate esters and additives in the electrolyte, as well as by impurities introduced during manufacturing or formed during storage. Therefore, qualitative and quantitative analysis of these components is critically important. In a previous publication, quantitative analysis of carbonate esters and additives in electrolytes was demonstrated using the Brevis GC-2050 + FID. In this report, equivalent quantitative analyses were conducted using the GCMS-QP2050, and additional qualitative examinations of impurities were performed. GCMS-QP2050, with its high analytical performance and space-saving design, contributes to highly precise analyses. Furthermore, combining it with AOC-30i auto-injector delivers enhanced accuracy, improved analytical stability, and increased productivity.
