The separator was cut along four directions: MD, TD, and two diagonal directions (45–1 and 45–2). The PP-D-B and PE-W-B with a width of 15 mm were directly cut by the specialized film preparation instrument (Labthink, China) to guarantee the repeatability of the experiment. But due to the high anisotropy of PP-D-U, the separator cannot be cut accurately …
The battery separator is a porous polymer membrane used to create a physical barrier between electrodes in a battery cell. The separator must be mechanically robust to ensure safe operation over the cell''s service life: mechanical failure leading to electrode contact can result in catastrophic failure of the cell. 1-3 Such failure often follows from puncture or …

For example, consider a three-layered separator with a PE battery separator material sandwiched between two layers of Polypropylene - PP Separator. The PE layer will melt at a temperature of 130°C and close the pores in the separator to stop the current flow; the PP layer will remain solid as its melting temperature is 155°C.
Knowledge of the compressive mechanical properties of battery separator membranes is important for understanding their long term performance in battery cells where they are placed under compression.

Owing to the demand for "green"'' products, lithium (Li)-ion batteries have received considerable attention as an energy storage system [1, 2].Although the separator, which is placed between the anode and the cathode, is not directly involved in electrochemical reactions, its structure and its properties play an important role in cell performance.
Battery Isolator: Manufacturers use diodes, relays, or solid-state technology to construct isolators. They control the current flow, allowing it to pass in one direction only and ensuring each battery operates independently. Battery Separator: Separators are made of plastic, rubber, or glass, providing electrical insulation between battery ...

The separator is an essential component for safety in the lithium-ion battery. It separates the electrodes, preventing them from short-circuiting. Charging and discharging the battery places thermal and mechanical stresses on the separator, and if it fails, the battery will discharge spontaneously, potentially leading to a fire or explosion.
