Rechargeable lithium-ion batteries (LIBs) have garnered a great deal of attention, with the rapid growth of newly emerging applications. Taking into account that a key factor governing battery performance is how to facilitate ion and electron transport, the roles of separator (membranes) in LIBs should not be underestimated. Currently, most widely used separators in LIBs are manufactured using polyolefin materials. These polyolefin separators have several advantageous attributes suitable for practical use in LIBs, however, their intrinsic limitations often raise significant concerns related to ion transport (cell performance) and electrical isolation (cell safety) between the electrodes. In this presentation, we demonstrate a new class of separators with well-tailored porous structure, thermal stability and chemical functionality. Based on comprehensive understanding of membrane structure and properties, applicability of the new separators to LIBs is explored. |
