Differential Scanning Calorimeter (DSC)

NEXTA® DSC series

NEXTA® DSC series

Measuring thermophysical properties of electrolytes, separators, and exterior materials.

NEXTA® DSC series, thermal analyzer, can evaluate the basic thermophysical properties of components such as electrolytes, separators, and exterior materials in lithium-ion batteries. With its thermogravimetry (TG), it is possible to measure the composition ratio of materials and simulate lifetime degradation.

This thermal analyzer can also be used for safety evaluation by observation of heat generation behavior of electrolyte and cathode material using differential scanning calorimetry (DSC). Comparing the DSC results, the electrolyte including cathodematerials generates heat at the lower temperature side than electrolyte alone. This is because the oxygen is released by thermal decomposition of cathode and the electrolyte is oxidatively decomposed. In this way, with the use of DSC, you can evaluate the thermal stability of a lithium-ion battery from the observed thermal decomposition onset temperature.

〈Concentration Analysis〉 Atomic absorption spectrophotometer (AA)



Measurement of trace impurity concentrations in materials

With ZA3000, you can obtain highly reliable data by using polarized Zeeman electric heating atomic absorption spectrometry that can accurately correct for background absorption. In addition to measuring the concentration of impurities in the active material, ZA3000 can also measure the concentration of impurities such as Mg in lithium hexafluorophosphate used in electrolytes. It can be applied to research and development of various materials at the battery design stage and quality control during production.
