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.
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.
A critical cell-level component of a lithium-ion battery which significantly impacts both overall electrochemical performance and safety is the porous separator that is sandwiched between the two active cell electrodes.
The most popular separator materials for Li-ion batteries with organic electrolytes are polyolefin materials [ 70 ]. However, the low melting point of polyolefins (135 °C for PE and 165 °C for PP) qualifies their utilization as a thermal fuse to shut down the cell by losing porosity and permeability if an over-temperature condition occurs.
It is crucial to obtain an in-depth understanding of the design, preparation/ modification, and characterization of the separator because structural modifications of the separator can effectively modulate the ion diffusion and dendrite growth, thereby optimizing the electrochemical performance and high safety of the battery.
There are many important components in the LiB, one of which is a separator that serves to block short circuits between the anode and cathode of the battery while providing a way for ion exchange to continue. This article summarizes important information related to battery separator technology.
