6 FAQs about [Is it difficult to produce lithium battery separators ]

How to choose a lithium battery separator?

The mechanical strength and thermal stability of the separator are the basic guarantees of lithium batteries’ safety. At the same time, the separator’s high porosity and electrolyte wettability are necessary conditions for the high electrochemical performance of lithium batteries . Fig. 1. (a) Schematic diagram for lithium battery.

What are the challenges of a lithium ion battery separator?

Despite the advances that have been made in the development of separator materials, there are still several challenges that currently exist. These challenges are primarily due to new and emerging applications of Li-ion batteries. Among the existing challenges of the separator, the main ones are: 1. Wettability of the Separator

Why is a lithium battery separator important?

As one of the essential components of batteries (Fig. 1 a), the separator has the key function of physical separation of anode and cathode and promotes the transmission of ionic charge carriers between electrodes . The mechanical strength and thermal stability of the separator are the basic guarantees of lithium batteries’ safety.

Can a multi-layer structural separator extend the life of a lithium battery?

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.

What happens if the thickness of a battery separator decreases?

As the thickness of separator is decreased, some of the mechanical properties, such as the puncture strength also decrease. This presents a safety issue for the batteries as it increases the potential for holes in the separator that can lead to short circuits.
