[Analysis Case] Lithium-ion Secondary Battery
Accurate evaluation of the separator cross-sectional shape through sample cooling.
The separator, which is a key component material of batteries, influences the characteristics and safety of the battery due to its porosity, shape, and other factors. Currently, mainstream polymer materials such as polyethylene (PE), polypropylene (PP), or their composite materials have low softening points, with PE being around 125°C and PP around 155°C. We will introduce a case where the structure of a PP separator with a low softening point was observed, and cooling was performed during cross-section processing to suppress degradation for evaluation.
