Even if it isn't as high-capacity, a longer-lasting and safer battery over a thinner smartphone isn't a _bad_ trade-off, specially considering chips and screens get more efficient. This might have more market than stationary batteries.
Are they safer? Sodium is also very highly reactive. Otherwise agreed, I'm very happy with form factor of 5-10 year old phones.

#13Lower capacity in the same form factor, but inputs are common and cheap as dirt and will be able to do the hard work of supporting grid scale battery storage. We've learned that there are many applications that do not need to capacity of lithium.
Not only that: > Natron says its batteries charge and discharge at rates 10 times faster than lithium-ion, a level of immediate charge/discharge capability that makes the batteries a prime contender for the ups and downs of backup power storage. Also helping in that use case is an estimated lifespan of 50,000 cycles. So you take up more space, but the storage system is better in every other way (agility, conflict min…

The fact it supports more cycles and tolerates a broader temperature range than Lithium counts points towards safety too. Lithium isn't happy above like 30 Celsius, which a fast charging portable device can _easily_ reach.

For land and sea transport it's mostly volume/kWh.
For electric aircraft it's kg/kWh.

I don't think the battery is a big block of pure sodium. That would be unsafe.
The battery electrolyte contains sodium ions, but the same is true of salt water and Gatorade.
I think the industrial source of their sodium is sodium hydoxide, a common industrial feedstock. https://en.wikipedia.org/wiki/Sodium_hydroxide
