ICP-OES and ICP-MS can be used to measure selected elements in appropriately prepared samples.

Applications may include raw material characterization, impurity analysis, and investigation of elemental composition. Method selection depends on the target elements, expected concentrations, sample matrix, and required detection limits.

Moisture Analysis

Water content can be an important quality parameter for many battery materials and processing steps.

Karl Fischer titration is commonly used for quantitative water determination in suitable samples. Sample preparation, contamination control, and method suitability should be considered when selecting a moisture analysis system.

Thermal Analysis

Differential scanning calorimetry and thermogravimetric analysis can help researchers study thermal transitions, decomposition behavior, and mass changes under controlled conditions.

The appropriate instrument depends on the material, temperature range, test atmosphere, and research objective.

6. Environmental Testing Equipment for Lithium Batteries

Battery performance can change with temperature and other environmental conditions. Environmental testing equipment helps laboratories evaluate behavior under controlled and repeatable conditions.
