SUMMARY
Polyolefin membranes, particularly polyethylene, can serve as separators in electrochemical cells, specifically in Li-ion batteries. While standard polyethylene, such as that found in grocery bags, may exhibit some natural porosity, its effectiveness as a separator depends on specific characteristics outlined in the referenced electrochemical literature. The article emphasizes that mechanical stress can enhance porosity, suggesting that not all polyethylene membranes are suitable without intentional modifications. Testing the performance of such membranes is recommended for practical applications.
