Analysis of Elemental Impurities in Anode Materials for Lithium-Ion Secondary Batteries Using the ICPE-9820

User Benefits

- Elemental impurities in the anode materials of lithium-ion secondary batteries can be measured. - Even after measurement, elements and wavelengths can be added to check for unexpected elemental impurities in the anode materials. - The system uses a mini torch that consumes less argon gas, thus reducing running costs.

Introduction

Lithium-ion secondary batteries (LIBs) are widely used in mobile devices, electric vehicles, hybrid cars, and more. One of the components of LIBs, the anode, accumulates and releases Li ions during charging and discharging. Graphite-based materials are mainly used as the anode material in LIBs. In China, one of the major producers, the analysis of elemental impurities in graphite, which is used as LIB anode material, is required by GB/T 24533-20191) using inductively coupled plasma atomic emission spectroscopy (ICP-AES). In this Application News, elemental impurities in LIB anode materials were analyzed using the ICPE-9820. Spike recovery tests were performed to confirm the validity of the analytical values. Additionally, the “Acquisition for All Wavelength” feature allows for checking the presence of elemental impurities that were not subjected to quantitative analysis.
