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.
The separator is an indispensable component in lithium-ion batteries and sodium-ion batteries and directly affects the electrochemical performance and, especially, safety. It is imperative to develop high-safety separators for rechargeable lithium-ion batteries and sodium-ion batteries.
The separator plays the pivotal role in normal LIBs and SIBs device and there is a close relationship between separator and battery safety , . The separator acts as a physical barrier to insulate cathode and anode from direct contact and accommodate electrolyte to facilitate ions shuttle inside the battery.
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 safety issues of batteries have become increasingly important and challenging because of frequent occurrence of battery accidents. The separator is an indispensable component in lithium-ion batteries and sodium-ion batteries and directly affects the electrochemical performance and, especially, safety.
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.
