Lithium-ion battery separators are receiving increased consideration from the scientific community. Single-layer and multilayer separators are well-established technologies, and the materials used span from polyolefins to blends and composites of fluorinated polymers.
Separators in lithium batteries are crucial for ion transport and preventing dendrite formation. Failure mechanisms like dendrite growth that can undermine separator effectiveness. Innovations in separator design are essential for improving battery performance and safety.
As the ‘third electrode’ material in batteries, the separator is a thin film with a microporous structure positioned between the positive and negative electrodes. Its primary function is to prevent direct contact between the electrodes while facilitating the normal transport of Li + ions and insulating electrons [3, 39, 40].
