Evaluation of the shape and composition of organic/inorganic multilayer structures.
The separator in lithium-ion secondary batteries not only serves the role of isolating the positive and negative electrodes to prevent internal short circuits, but in automotive batteries, it is also required to have heat resistance to prevent a decrease in strength or melting even in high-temperature environments. This report introduces a case study on separators used in overseas automotive batteries, where heat resistance and thermal decomposition behavior were investigated using TG-DTA, and structural and compositional evaluations were conducted using SEM-EDX, FT-IR, XPS, TOF-SIMS, and XRD. It was found that the separator used in the battery consists of a porous polyethylene and a layered structure of polygonal AlO(OH) aimed at heat resistance.
