6 FAQs about [What are the bonding materials for battery separators ]

How does a battery separator work?

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].
