The modified separators were cut into strips of 25 mm width and laminated to a graphite anode as described above. The interface between separator and anode is prioritized for investigation, since adhesion there is generally lower compared with the separator-cathode interface due to the use of non-thermoplastic binders in the anode.
The battery coin cells assembled with the PI separator displayed robust durability and could still function after being heated at 140 °C for 1 h, whereas those with the commercial PE separator could no longer charge due to the shrinkage of the PE under the same circumstances.

A battery separator is a permeable membrane that keeps the anode and cathode, the battery's electrodes, apart to avoid an electrical short circuit. It is a critical component. The anode is the positive electrode, and the cathode is the negative electrode.
At present, polyolefin microporous membranes, such as polyethylene (PE) and polypropylene (PP), are the most widely used separators. The low melting point of polyolefins (135 °C for PE and 165 °C for PP) leads to poor thermal stability of separators, seriously affecting the safety of batteries.
