Sodium ion batteries is better for the enviroment than lithium

[Agent]

Electric cars will never be good for the environment until they find an alternative to lithium. Sodium seems like the best and most likely alternative with active research and development around the world.

Once this happens there will be no solid argument to be made against electric cars powered by sodium ion batteries.

I've heard about wood-based batteries development too. Could be very fun indeed.


So-ion batteries should have a better capacity/weight than lithium one, but right now, it's the lithium technology that's the most studied and upgraded. Because their capacity per wieght ratio is GOOD. For home appliances. Because when you're talking about a car or a long range truck with cargo ... it's battery weight ranges in tons. Wood batteries would take like 90% of the cargo space xD

I've seen some ideas about adopting a hybrid system for using a smaller lithium ion battery as a "boost" but for prolonged lighter usage the sodium would be used. This hybrid style could be a decent compromise until sodium further improves. It'd still take the amount lithium extraction down.

It's not just about battery capacity, it's also about ease of recharging.

You can fill up a car in about 5mins. EVs take too long to charge.

You can just charge the car overnight. Wall mounted charges for your home are low cost. And for apartment districts their carparks normally have EV charging points.

Super long distance drivers are a niche. Although the average driver distance in somewhere like America is probably a lot more given just how huge the place is.

While sodium ion batteries may have lower upfront energy demands, do people forget that the production process will still generate substantial greenhouse gas emissions?

Lithium is often sourced from countries with high labor standards and environmental regulations, such as Chile and Australia. Sodium, on the other hand, is primarily extracted in countries with lower regulatory environments, such as China.

The environmental impact of lithium mining is relatively small compared to other metals.

So, not inherently better for the environment when considering the broader context of energy density, recycling infrastructure, resource extraction, and production emissions.

If i was an exploitant, i'd use the old horse coatch system : changing the battery on site, as they did change the horses at the stops. Just swap a freshly charged accumulator for the spend one and charge the spend one until the next custommer arrives. But that would need accessible battery packs, an infrastructure for the batteries swapping, and an overhaul of the batteries system itself with compartimentation of the alimentation blocks.

An EV is just not practical for me at all. While going back and forth to the grocery store is one thing I may do very frequently, I also drive quite a distance regularly to visit friends. If charging stations were much more common, then... "maybe." But, they're not. They can be common in more dense urban areas and there are probably several in/around the more urban areas of the town I live in. (A very "environment-conscious" place/people, here)

But, for me? No, it's not practical.

Some people don't appear to understand that because they just don't have any experience outside of more heavily populated urban areas. And, for some, a "long drive" is just about anything over an hour... For me, a "long drive" is six+ hours.

Sodium ion doesn't have a better capacity for the size of the battery so they'd suck for a vehicle. Not a bad choice for stationary power storage though.

That runs into it's own problems. Where do the batteries all come from? Which brand, technology, suppliers, what serious counterfeits from using the swap system to launder authentic parts

Yeah, the really fun question is, what is stopping people from just burying a live rail in all roads, or doing them overhead, so giant EV battery for interstate and urban can just be ditched.

We already have an electric grid, this would be an adaptation of what was there.

It'd add some grid resilience too and could be used for high-speed internet if they bundle fiber with it too. Electric trains essentially do this already. Make for much lighter vehicles.

Fairly sure I seen electric buses do this in some Euro nation or the other, overhead power. Lots of places use electric trams, the overhead kind.

Probably help with autonomous driving too, then you could have a centrally managed traffic flow, or locally if that's just too much data.

They could do something similar for canals/rivers. So ships and boats that travel in lanes won't need hulking battery's.

Don't think its viable for the open ocean, would be cool if a cable line could float to that end, well suspended underwater like 25m deep off the coast or something.

You'd probably see the buoy network from space it'd be so pervasive, the major international shipping lanes mostly, for those giant cargo ships and mega port cities.

The upfront cost might suck, but the stuff ought to be good for decades once done.

I'd love to do the maths on it, but, it'd be off because at that scale, there should be some kind of cost reduction, for the 10's millions of miles of cables and ancillary support infrastructure to make it work.

It is something that should pay it forward for future generations, with proper maintenance such a system could last for 100's of years, maybe even 1000's, if built to be serviced right.

Definitely bring the world together at least for trade and transport. Some crazy fun engineering challenges too.

If you support child slave labor, I suppose they're all great.
