Apparently, no one read the article. The primary application of this was for the military. The article is based on research done by DARPA. For military use, lithium ion batteries have way too short of a lifespan and the charge times are too long. Also, they can catch fire and burn for a long time, probably a real problem in a military context.
Flow batteries can mitigate all these issues and they’re cheaper and lighter. They can be made from inexpensive materials that are more readily available than lithium.
Given these benefits, it seems obvious that consumer applications will take off. The original researchers see an opportunity here and that’s why they formed a company.
Your cited lithium ion “20 min” charge time is for super chargers only, and in many cases is actually more like 40-45 minutes. Also, super charging is bad for the battery. In all other cases, you’ll be using an L1 or L2 charger which will take anywhere from 8 hours to 72 hours to charge a vehicle.
And, eventually, the lithium ion battery will lose its range as the battery degrades, making the whole car as disposable as that 3-4 year old smartphone you had to toss because the battery can’t hold a charge anymore. Flow batteries will keep refuel times to the same as they are today, and the material can be recharged up to 10,000 times, a huge improvement over lithium ion. And, the lifespan of your car won’t be literally glued and bolted to the lifespan of your battery.
Why do people get hung up on the supercharging stop they would need to make 2-3 times a year and ignore the 40x a year they currently go out of their way to wait in line for cheap gas at Costco?
Also, there are Teslas with 250k miles and 90% range. The batteries can already outlast their vehicles, and finally, recycling batteries is possible and a lucrative business.
I have a minimum of eight ~500 mile drives I have to make in a year. I drive a plated and insured golf cart for most of my trips but theirs no way I’m tethering myself to a power cord when I can, with great confidence, pull over and fill my minivan in ~5 minutes wherever I’m at once I get to a quarter tank of fuel. I also end up with several trips a month where having a minivan is convenient as hell. I’d love to be able to reasonably jettison fossil fuels at some point so I don’t understand the criticism towards discovery, engineering, and evaluation of a broad spectrum of solutions and applications.
