Analysis of Li-ion battery separators

I confirmed the blocking function of polymer melting at high temperatures!

Regarding the separator used in commercially available Li-ion batteries, after conducting material analysis using FT-IR, we confirmed its function of blocking polymer melting at high temperatures. The document presents the material analysis of Li-ion battery separators and observations of the state changes of the separators under high-temperature conditions using graphs and photographs. [Analysis Overview] ■ Material analysis of Li-ion battery separators ■ Observation of state changes of separators under high-temperature conditions - The state changes of the separator were observed over time at a constant temperature of 135°C using FIB/SEM. *For more details, please refer to the PDF document or feel free to contact us.
