Could you please explain what means the term single wall and multi wall in this context?

What is your source?

Of course, this is a very theoretical value, these super Nanotubes are not available in industrial scale and the flywheel also needs sprockets and a massive housing, much like how Expert Electrical installs require careful planning and proper safety measures, which should prevent a catastrophe in case of flywheel disintegration. Even if the housing stays intact, a bursting flywheel could cause the whole vehicle to spin and throw out its passengers...

For batteries using little or no exotic materials, look into sodium-ion, zinc-based, or organic battery chemistries. Reliable sources include scientific journals like Journal of Power Sources and Energy Storage Materials, university research publications, and government or industry reports from groups like the U.S. Department of Energy. Preprint servers like arXiv and ResearchGate also provide early access to research on low-metal or metal-free batteries.

Well, how does it help with a flywheel?
 
Superconducting flywheel being researched and developed by JR Central
https://www.jreast.co.jp/development/theme/energy/energy02.htmlThe superconducting flywheel energy storage system uses superconducting technology to levitate a large disc (flywheel) and rotate it to store regenerative power as kinetic energy (charging), and then converts that kinetic energy back into electrical power (discharging) as needed.

Compared to lead-acid batteries and lithium-ion batteries, it offers advantages such as less degradation from repeated charging and discharging, and the elimination of maintenance due to wear caused by the levitation and rotation of the flywheel. Currently, a demonstration test is planned at the Anayama Substation on the Chuo Line (Nirasaki City, Yamanashi Prefecture), with the expectation of effectively utilizing approximately 400 kWh/day of regenerative energy and reducing CO2 emissions by approximately 64 tons per year.

JR Central is a Japanese railway transportation company.

Zinc-air
https://techxplore.com/news/2026-06-strategy-oxygen-reduction-zinc-air.html

Batteries are undergoing rapid advances. For example, modern zinc-air batteries have the remarkable ability to use oxygen as energy—but that oxygen isn't stored in the battery itself. Zinc-air batteries take in surrounding oxygen to undergo a reaction to discharge energy called the oxygen reduction reaction (ORR). While this convenient strategy is promising, the slow speed of the ORR limits the practicality of these batteries. However, researchers at Tohoku University found a method to enhance ORR activity using a catalyst with a precise configuration of iron (Fe). Their remarkable heterointerface—which is a combination of Fe2O3 and Sm2O3—accelerates ORR kinetics by inducing charge redistribution, orbital hybridization and super-exchange-mediated spin modulation. In other words, they have fine-tuned an efficient and sustainably sourced catalyst to bring out the true potential of zinc-air batteries.

If homes came with batteries that could provide a week's worth of electricity, we could massively downsize the distribution infrastructure. In fact, we might be able to get rid of wires and use lasers, which are currently impractical because they got blocked by rain and fog, with customers using their batteries during those brief weather related interruptions.
 
For new battery tech, maybe it's time to go old-school:

"But engineers in the early 1800s once created a small battery that still, to this day, has not run out. It’s the world’s longest lasting battery, and it’s also a bit of a mystery to modern scientists."

"It has rung well over 10 billion times, earning it a Guinness World Record for being the “world’s most durable battery.”"
