AI Customer ServiceThe separator is a passive component of LIBs but plays a pivotal role in determining the electrochemical performances and safety of batteries.
Furthermore, the component–structure–performance relationship of separators is summarized, and the impact of separator compositions and structures on the safety of LIBs is emphasized. In addition, the future challenges and perspectives of separators are provided for building high safety rechargeable lithium batteries.
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.
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.
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.
