Applications of Laser Thermal Conductivity Analyzers Across Industries

A laser thermal conductivity analyzer measures thermal conductivity, thermal diffusivity, and specific heat capacity. The analyzer uses non-contact heating for materials development, quality control, and process evaluation in new-energy materials, semiconductors, aerospace, and building materials. For lithium-ion battery cathodes, anodes, separators, and electrolytes, thermal-conductivity measurements are used to evaluate heat dissipation. Low thermal conductivity can allow heat to accumulate during charge and discharge and increase thermal-runaway risk, while high thermal conductivity may affect local reaction stability. In photovoltaic materials, the analyzer tests solar-cell backsheet materials and EVA encapsulation films. One example compares film formulations, reports a 20% increase in thermal conductivity, a 5 °C reduction in photovoltaic-module operating temperature, and a 3% increase in power generation. In semiconductors and electronics, the instrument tests chip substrates, thermal grease, and thermally conductive silicone sheets. It is also used to test thermal materials in 5G radio-frequency modules and the thermal conductivity of LED heat-dissipation supports. For aerospace and manufacturing, it is used for high-temperature testing of turbine-blade materials and for testing spacecraft insulation. In building materials, thermal-conductivity testing of insulation materials is used to assess their conformity with building energy-efficiency requirements.
