Located between the anode and cathode of the battery, it prevents physical contact between the electrodes, while the separator facilitates the transfer of ions in the battery. It can affect key properties such as capacity, cycle performance, and charge-discharge current density of lithium batteries.
With the growth of electric vehicles and the phasing out of internal combustion engines in Europe, innovations in separators for lithium batteries have also come to the fore. The separator has got thinner and the structure has changed.
Although the separator is not involved in the electrochemical reaction of lithium ion batteries, it plays the roles of isolating the cathode/anode and uptaking the electrolyte for Li + ions transport, and therefore directly affects the safety and electrochemical properties of lithium ion batteries.
Huang et al. designed a multi-layer structural separator to prevent the “shuttle effect” of soluble polysulfides, and therefore extended the cycling life of battery [ 34 ]. The lithium metal anode and silicon anode have the problems of serious volume expansion, unstable SEI film and lithium dendrites.
Multifunctional separators offer new possibilities to the incorporation of ceramics into Li-ion battery separators. SiO 2 chemically grafted on a PE separator improves the adhesion strength, thermal stability (<5% shrinkage at 120 °C for 30 min), and electrolyte wettability as compared with the physical SiO 2 coating on a PE separator .
As part of the battery value chain, separator companies also have a strong commitment to sustainability and the circular economy, in minimising waste, optimising production processes and achieving the lowest possible emissions, as well as localising the material supply base.
