Separators are indispensable components in lithium-based batteries without being directly involved in the electrochemical reaction of batteries.
Unfortunately, most studies in the field of lithium-based batteries have only focused on separators between 20-25 μm so as to achieve a balance between battery safety and performance.
However, such thick separators come at the expense of less free space for accommodating active materials inside the battery, thus impeding further development of next-generation lithium-based batteries with high energy density.
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.
Thin separators with robust mechanical strength are undoubtedly prime choice to make lithium-based batteries more reliable and safer. Recently, great accomplishments have been achieved for advanced thin separators used in LIBs and a detailed discussion is following in this section. 5.1. Functionalized polyolefin separators
The porosity is definitely the basic requirement for separators of lithium-based batteries to transport Li ions. A sufficient amount of liquid electrolyte should be trapped within micro pores and interconnected channels in separator to sustain a high ion conductivity.
