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.
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].
Developing suitable separators will be critical to the future development of the rechargeable batteries. The properties of the separators, such as porosity, aperture, wettability, thermal behavior, ionic conductivity, and mechanical strength, decide the performance of the batteries.
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.
Organic coating can obtain a non-woven fabric with a uniform pore size, and at the same time enhance the puncture strength of the non-woven fabric separator, improve the compatibility and adhesion of the separator to the battery electrode, and reduce the internal resistance of the battery.
