6 FAQs about [Punching holes in the energy storage battery box shell]

Can punching holes on electrodes improve rate capability of paper-like supercapacitors?

The strategy of punching holes on electrodes is a low cost, simple and universal approach to improve the rate capability of paper-like supercapacitors, and also has enormous potentials for realizing high rate capability of other emerging paper-like electrodes, such as graphene, MXene, MoS2, and so on, for various energy storage devices.

What happens if a battery separator fails in a punch test?

In punch test of the whole battery cells, due to the friction from cathode and anode particles, the separator is mostly expected to fail in Mode A, and not to reach Mode B. With the start of thinning and appearance of transparent section, friction would lead to instant localization.

What is a punch test for lithium ion battery separators?

It represents combined in-plane biaxial tension and out-of-plane compression. A punch test with a small radius punch head is one of the standard abuse tests for lithium-ion battery separators. It is performed with a punch of 3.2 mm in diameter according to ASTM F1306-90, and usually referred to as a puncture test 25.

Can a supercapacitor improve rate performance by punching holes?

The availability of such strategy has been further verified by the assembled supercapacitor devices. In addition, we have proved that an additional electrochemical treatment for increasing the specific capacitance would not make negative influence on the acquired improvement of rate performance by punching holes.

Why is the mechanical integrity of battery separator important?

The mechanical integrity of battery separator is critical for prevention of internal short circuit. A better understanding of the mechanical behavior and failure mechanisms of the separators may assist in explaining an apparently conflicting response.

Does separator integrity prevent internal short circuit in lithium-ion batteries?

Scientific Reports 6, Article number: 32578 (2016) Cite this article Separator integrity is an important factor in preventing internal short circuit in lithium-ion batteries.
