Customer ServiceAs 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.
Separators are one of the important components of lithium-ion batteries since they can isolate the electrodes and prevent electrical short-circuits. The separator is a key element in all lithium-ion battery systems since it allows the control over the movement of ions between the anode and the cathode during the charge and discharge processes.
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.
The electrolyte bridges the positive and negative electrodes by forming an ion-conductive channel between them. 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.
