New energy materials—the four main lithium battery materials (cathode, anode, separator, electrolyte) and photovoltaic encapsulation materials (EVA/POE films, backsheet)—have testing systems that are among the most technically demanding in the new materials industry. Safety is the top priority.  

For lithium battery material testing: Cathode and anode materials need TGA to determine thermal stability and residue content, and DSC to assess thermal runaway temperature and heat release—which are core input data for battery safety design. Separators require a universal testing machine equipped with micro-force sensors (10N-500N range) and a non-contact extensometer to accurately measure the tensile strength, elongation at break, and puncture strength of ultra-thin 10-25μm membranes (ASTM D882/D4833). Electrolyte component analysis relies on GC-MS or HPLC. The coating process compatibility of electrode slurries is evaluated via flow curves and thixotropy tests using a rotational rheometer.  

For photovoltaic material testing: EVA/POE encapsulation films require DSC to measure crosslinking degree, a universal testing machine to test peel strength (adhesion between the film and glass/backsheet), and TGA to determine VA content and thermal stability. These tests are directly related to the 25-year service life reliability of PV modules.
