3. Summary and Outlook The separator is a crucial component in Li-ion batteries with the function of preventing physical contact between the positive and negative electrodes of the battery and stopping internal short while serving as the electrolyte reservoir to enable ionic transport.
Separator, a vital component in LIBs, impacts the electrochemical properties and safety of the battery without association with electrochemical reactions. The development of innovative separators to overcome these countered bottlenecks of LIBs is necessitated to rationally design more sustainable and reliable energy storage systems.
The small amount of current that may pass through the separator is self-discharge and this is present in all batteries to varying degrees. Self-discharge eventually depletes the charge of a battery during prolonged storage. Figure 1 illustrates the building block of a lithium-ion cell with the separator and ion flow between the 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.
Coatings of different materials (metals, oxides, nitrides, etc.) on the separator have good mechanical properties and can promote the uniform passage and deposition of Li +, which effectively inhibits the growth of lithium dendrites.
The battery separator mainly plays the role of isolating the anode and cathode and ensuring a certain ion transmission. The porosity distribution, pore size, electrolyte wettability, and mechanical properties of the separator will directly affect the battery’s performance.
