What Happens During Nail Penetration of Solid-state Lithium Battery?
Solar PV homeowners will love solid state energy storage systems because they offer superior performance and are non-explosive, non-flammable, non-toxic, and 100% recyclable??
The nail penetration test of solid state battery is something that anyone interested in the latest technology trends should be interested in. Solid-state batteries have been gaining popularity because they are lighter, safer, and more reliable than traditional lithium-ion batteries that are currently used in most consumer electronics.
Recently, Vnice team conducted a test of a solid-state battery by literally “poking it with acupuncture.” The aim of the experiment was to test the safety and reliability of the newer type of battery.
It was suspected that the acupuncture would produce an electric current that would disrupt the circuit of the battery, causing it to short circuit. However, the experiment showed the opposite. After the needle was inserted into the battery, the voltage of the battery remained stable throughout the course of the experiment. This suggests that the acupuncture did not affect the battery’s performance.
The voltage is 3.47V before the acupuncture experiment
The Voltage is 3.43V after the acupuncture experiment
What’s more, the test showed no smoke, fire or liquid leakage. This indicates that the battery was not damaged at all, proving that the acupuncture did not have any adverse effect on the battery.
The experiment was the first of its kind, and it showcases the potential of solid-state batteries in terms of safety and performance. The findings of the acupuncture test suggest that these batteries can be put through rigorous testing, without having to worry about damage or other safety issues.
The results of the experiment also highlight the potential of the Solid-state battery in the commercial market. As the technology continues to develop, these batteries could become a viable alternative to the traditional Li-Ion batteries. The fact that the needle did not cause any damage to the internal components of the battery, while still remaining stable, is a testament to the reliability of the product.
The experiment consisted of using needles to create small holes in the surface of the battery. The researchers applied varying levels of pressure to the offending area and measured the voltage of the battery during the entire process. After the needle penetrated the battery, the voltage remained unchanged, demonstrating that the battery was able to maintain its performance despite the pressure.

I was interested when I saw this video last month. https://www.youtube.com/shorts/Ed2QAG7b4QM

I did not watch the video or carefully read the post but there are many YouTubes of fires with this nail puncture fire/smoke scenario. It is used for beach parties or trips out into the desert. Mainly drill batteries and drone batteries in these videos.
The key is the type of Lithium. The LFP type lithium has shown to be very safe but still has a small chance of bad things happening when abused.
The type that has shown to be super dangerous to the nail test is the type NMC lithium. It was used alot in Tesla but is being phased out, slowly.
NMC type lithium has one of the densest energy to weight ratios and the Tesla Roadster had them as an upgrade.
I also think calling Lithium solid state is a bit off the mark. I do get it, but would add that lithium batteries do depend on the BMS and are damaged when charged below 32F.
With all of the great advantages to lead acid, lithium does add electronics/cold charging as new failure modes that lead acid does not have.
Cost/recycling also can be an issue. It is all a tool is the design box.

Does it matter if you hand bang the nail or is it different if one uses a nail gun? If using a lithium battery powered nailer to nail the lithium battery are they additive or inverse?Off Grid.

The needle test is mainly to short-circuit the inside of the battery, so it's the same whether you hand bang the nal or uses a nail gun.

The latest BYD blade batteries pass the nail test with flying colors. Be on the lookout for these blade (not pouch) batteries to become the world standard.23.16kW Kyocera panels; 2 Fronius 7.5kW inverters; Nyle hot water; Steffes ETS; Great Lakes RO; Generac 10kW w/ATS, TED Pro System monitoring
