The separator prepared by the wet method can effectively inhibit the occurrence of lithium dendrites on the graphite anode during the charge process due to the curvature of the pores and the interpenetrated microporous structure, and thus is more suitable for the battery with long cycle life.
As one essential component of the rechargeable batteries, the main function of the separator is to separate the positive and negative electrodes, restrict the free pass of electrons and prevent short-circuit of the battery. At the meantime, it allows the metal ions in the electrolyte to migrate freely between the electrodes [21, 22].
After absorbing the electrolyte, the separator is easily separated due to swelling, thereby affecting the performance of the battery. Besides, the composite separator is usually very thick, and shows higher internal resistance, which also affects the ionic conductivity and the discharge capacity of the battery [49, 100, 101]. 3.2.3.
Separator is critical to the performance and safety of the rechargeable batteries. The design principles and basic requirements for separators are overviewed. The modification strategies in tailoring the separators' properties are discussed. Separators with high-temperature resistivity and better safety are desirable.
The use of oxide coatings in modified separator batteries (such as Sn 2 O) will form a mixed modified layer of lithium–metal alloy and Li 2 O in situ with the lithium anode during the electrochemical cycle. Li 2 O can act as a good conductor of ion transfer, and Li 3 N has a higher ionic conductivity than lithium oxide.
