Capacity is twice that of lead-acid batteries...KDDI demonstrates zinc secondary batteries as backup power source for base stations
https://newswitch.jp/p/41208
KDDI announced on the 11th that it has begun a demonstration test to use zinc secondary batteries being developed by NGK as backup power equipment for mobile communication base stations. Zinc secondary batteries weigh half as much as lead-acid batteries used in many base stations, allowing more space for installation. With the same size and twice the capacity, base station operating time can be extended to up to 72 hours.

In the demonstration, the system will be operated in a real environment for one year, and operations will be verified through seasonal changes in temperature and humidity, as well as power outage tests.

https://aukehoekstra.substack.com/p/batteries-how-cheap-can-they-get
Personal take aways: Raw material costs:
NMC: $50kW/h at 300Wh/kg
LFP: $12kW/h at 200Wh/kg
Sodium: <$5kW/h at 160Wh/kg

Basically saying there is still quite a bit of space to go in production costs.

On a different scale...
Seasonal thermal energy storage
https://en.wikipedia.org/wiki/Seasonal_thermal_energy_storage
"the storage of heat or cold for periods of up to several months....
For example, heat from solar collectors or waste heat from air conditioning equipment can be gathered in hot months for space heating use when needed, including during winter months. Waste heat from industrial process can similarly be stored and be used much later or the natural cold of winter air can be stored for summertime air conditioning."

Another means of storing electrical energy is a flywheel. One made of single wall carbon nanotubes could offer energy density of 53,418 wh/kg, which is over 4 times higher than gasoline. Flywheels can also "charge" much faster than any battery and are simpler to manufacture.

The amount of angular momentum should make vehicles based on them very "interesting"

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 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 it's passengers...

Here's my source: https://www.mdpi.com/1996-1073/8/10/10636

You can avoid safety issues by having multiple smaller flywheels just like how batteries have multiple cells, albeit for different reasons.

And this sort of power density could make these flywheels into very effective explosives.

 

[Nicknick]

I suppose, multi walled could mean, that the inner flywheel housing could rotate in the outer housing in case of a flywheel disintegration to prevent the vehicle from a catastrophic spinning.

No, single and multiwalled refers to the nanotubes

I can't see any graphics in youre source, so what does it mean?

If that energy content would be realistic, a SSTO rocket would become feasible by a flywheel powered hydrogen pump without any combustion....

They're simply two different types of carbon nanotube with different properties.

Why hydrogen? Why not something less explosive?
