EV: Double the range, 5 minute recharge

[sun rise]

Some skeptics have attacked EV cars on the basis of current battery capabilities. I asserted that with some work we'll fix those issues. And then today, I read this very positive new development

https://phys.org/news/2020-02-high-capacity-ev-battery-materials-range.html

...development of silicon anode materials that can increase battery capacity four-fold in comparison to graphite anode materials and enable rapid charging to more than 80% capacity in only five minutes. When applied to batteries for electric vehicles, the new materials are expected to more than double their driving range.
...
"We were able to develop carbon-silicon composite materials using common, everyday materials and simple mixing and thermal processes with no reactors,...The simple processes we adopted and the composites with excellent properties that we developed are highly likely to be commercialized and mass-produced. The composites could be applied to lithium-ion batteries for electric vehicles and energy storage systems (ESSs)."

That's great news.

Electric vehicles already have enough range to satisfy the vast majority of our driving needs. Few of us go more that 20 miles one way to work, or to do the errands that we regularly use our cars for. And on the rare occasions that we would need to cover greater distances we could easily rent a small generator trailer to pull behind our cars to recharge them en route. And doubling that battery range only makes them that much more effective for the vast majority of us.

The real issue is cost. Every aspect of an electric car is much simpler and therefor should be much cheaper than an I.C.E. car with the exception of the battery and battery replacements. So, hopefully, this development will help in that one last area of reticence.

But I'm not holding my breath, because we don't make cars to transport us from place to place. We make them for money ... as much money as we can get away with charging for them. So even though we could build very functional, efficient, inexpensive electric cars. We won't.

The problem I have with batteries is not charging or range but the poisons they create under use and disposal after their cycle of use is done currently 10 to 20 years.

As opposed to what?
What happens to the exhaust from a gasoline motor?

At least with batteries you've got what you've got. Sequestration. Recycling. Whatever.
Somebody has to deal with their own waste.

With exhaust pipes, owners just dump their trash on everyone.
That's why gasoline and diesel is cheap power compared to electricity. Users of fossil fuels aren't required to clean up after themselves.

How is the electricity used to charge your batteries generated?

 

[columbus]

How is the electricity used to charge your batteries generated?

You really need a list of the sources of electricity?

Well, I guess a Deplorable might.

Could be most anything.
Nuclear, hydroelectric, wind, solar, fossil fuels, Scots turning a wheel...

The difference is that all of those sources are contained. The consumers can't just dump their waste and expect everyone to deal with it "equally".

You and Mr Van fully expect that. And you expect that socialist road system to be there for you. Because you know that subsidizing fossil fuels, and the industries built around that, is What Made America Great. And Trump will keep doing it, even if it means war with Iran.
And maybe China, but that's further off.

More efficiently than an internal combustion engine.

I think you might could be missing the point about electric vehicles needing
a source of electricity. Its generation poses environmental costs. Now I'm
not saying they're worse than tailpipe emissions. But consider them.
Michiganistan, for example, only recently stopped generating much of its
power by burning coal. But those plants have largely switched to nat gas.

 

[Revoltingest]

More efficiently than an internal combustion engine.

That would be part of an answer, but not one by itself.


Note:
While electric vehicles aren't practical for my purposes,
I look forward to the day when they are.

Now instead of carbon monoxide emissions, the new crisis will be ozone pollution.
