Separators are an essential part of current lithium-ion batteries. Vanessa Wood and co-workers review the properties of separators, discuss their relationship with battery performance and survey the techniques for characterizing separators.
Over the last five years, cellulose-based separators for lithium batteries have drawn a lot of interest due to their high thermal stability, superior electrolyte wettability, and natural richness, which can give lithium batteries desired safety and performance improvement.

Mechanical modeling of battery separator based on microstructure image analysis and stochastic characterization. J. Power Sources 345, 137–145 (2017).
Traditional polyolefin separators showed low thermal stability, poor wettability toward the electrolyte, and inadequate barrier properties to polysulfides. To improve the performance and durability of Li-ion and Li–S batteries, development of advanced separators is required.
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.
Nonwoven separators including cellulose (NKK), PET (Mitsubishi), aramid (Freudenberg), and polyolefin separators including PP (Celgard) and PP/PP (Celgard) were investigated for high-power lithium-ion batteries. The surface morphologies of the separators were observed by a field emission scanning electron microscopy (SU1510, Hitachi).
