Curious how it'll perform in real world conditions. Sodium batteries are supposed to have much better charging times and don't degrade the way lithium batteries do, both of which would be huge. Fingers crossed they live up to expectations.
(Also obligatory "expand and improve public transit damnit!")
As some used to "gotchas" and things aren't free, I'm wondering what kind of shortcomings[1] these batteries have that others do not.
[1] for example acid batteries can push a lot of power, but they are heavy and contain lead and well... acid. The nickel cadmium doesn't contain lead and acid, but has memory so you should follow discharge them before charging again. They are lighter, but still not light. Lithium ion are light, don't have memory, but can explode, also lose life if they are kept fully discharged or charged for long periods of time. They also slowly discharge when not in use, mainly due to protective circuit needing electricity to run.
Their only downside is having a little less energy density than lithium ion ones. You need a larger battery for the same capacity basically.
Everything else is a positive - they are even non-flammable and the materials to make them are abundant and easy to obtain.
Thanks. That's awesome to hear.
Interested to know about durability also :-)
expand and improve public transit dammit!
Currently living in Shenzhen and you'd be surprised that you can actually have it both ways. You can get around via transit quite easily, but also driving isn't too difficult. The problem with US cities is mostly just single family homes, which waste a bunch of space. If everything is less dense, you have to drive further to get to where you want to go, and building public transit makes less sense since it needs to service more areas to reach the same amount of people
