Major Component and Elemental Impurity Analysis of Lithium-Ion Cathode Materials Using the ICPE-9820

User Benefits

- The system uses a mini torch that consumes less argon, thus reducing running costs. - Measurements are stable with minimum long-term and daily fluctuations. - Post-measurement addition of elements and wavelengths is simple, enabling quantification at optimal wavelengths without re-measurement.

Introduction

Lithium-ion secondary batteries (LIBs) are used in many products, such as smartphones and electric vehicles, because they are small and lightweight yet offer high capacity or energy density. However, there is a risk of ignitionand heat generation, makes ensuring safety a critical issue. The elemental composition of cathode materials is known to be one of the most important factors that affect energy density and safety. In this Application News, the main elements and impurity elements of LIBs cathode material were analyzed using the ICPE-9820. Validation tests on the analysis values and stability tests (2.5 hours variation, 5 days daily variation) on the main components were performed.
