Skip to comments.New 'semi-solid' battery could recharge EVs as fast as pumping gas

Researchers at MIT reckon they've struck oil. In fact, you're looking at what they call "Cambridge crude" -- a substance that could halve the weight and cost of EV batteries and make them quicker to charge too. The black goo is packed with a high concentration of energy in the form of particles suspended in a liquid electrolyte. When separated by a filter, these particles function as mobile electrodes that can be pumped into and around a system before the energy is released. So instead of waiting up to 20 hours to juice your Nissan Leaf, you could potentially just pump this pre-charged substance into it -- rather like dirty old gas. Until now, no such "semi-solid flow cell" has been able to hold useful quantities of energy, but this stuff literally oozes with it. Not only could it power EVs, it could even be used for large-scale electricity storage for utilities. The researchers insist this energy revolution is years off -- but when it comes, there will be blood.
“The black goo is packed with a high concentration of energy in the form of particles suspended in a liquid electrolyte.”
Brawndo? It has electrolytes!
he grid melts down and the whole country goes dark.
Like North Korea?
I heard a quick chemical reaction. Not sure.
Seems like something with potential for standby/reserve power aps. Right now utilities with significant numbers of NUGs, (non-utility generators) have to keep a lot of capacity, (at considerable expense)on “spinning reserve” ready to meet demand surges and keep the grid stable. “Peaking” plants using gas turbines and NG fuel exist to quickly take up load surges. Some of these conditions might well offer practical application for this “goo”. I’m for anything that decentralizes and localizes our power sources. >PS
Nah, it’s that electric plasma stuff from Demolition Man.
You haven't factored in the loss while the electricity passes through power cables from the plant through the grid.
Batteries degrade. They charge less, as they age.
this is not true. You have bought into the liberal “climate warming” “carbon” midset.
The goal is NOT to lessen carbon footprint rather CHEAPER and BETTER. That’s what will WIN!
So, the source of the fuel does not matter. The “goo” recharged at for example 10 cents/KWH is still about 10 times cheaper than gasoline. No matter WHERE the energy comes from.
This whole “carbon dioxide is pollution” nonsense is junk science, pure and simple.
WTF? where did I say anything about carbon?
I’m talking about cheap juice
Slap on a couple of E-catylisers in your car and go back to steam powered vehicles.
The average coal plant is 28 percent efficient, with the best around 45 percent. I think known battery technology is around 50 percent. I’ve read of a Mazda project on a 30 percent engine. I’d like to know what the efficiency of a Prius is, as it seems to be a much better concept than a plug in. I did a calculation once on how much power it would take to charge batteries in a ‘battery swap’ station. The same could be done for an ooze station. Assume 8 pumps, 75 percent used for 12 hours a day, with 10 minutes a fill up....at 10 kwh per fillup. Each night, the station would have to impart over 4,000 kwh over a 12 hour period....and this is just one ‘filling’ station, to let people get 40 miles, with today’s technology. When thee gas station has to knock down the car wash to make room for the transformer, it starts to look very inefficient to me. There are losses in transmitting and stepping down this kind of power.
you implied that coal fired is not cheap.
Im for anything that decentralizes and localizes our power sources.
Absolutely. We should just stop all this stupid research into “new” things. We’ll never use it. We already have everything we’ll ever need. What good has new technology ever been, anyway?
‘You haven’t factored in the loss while the electricity passes through power cables from the plant through the grid.’
I’m not down with global warming, and these
hybrid cars are a joke.
That said, gas and oil prices may only get worse,
and I’ve wondered if solar cells wouldn’t
be a perfect application for cars.
Sit it right on the roof.
We’ll still neet oil for many things;
but solar cars, to me, sounds like a better
idea than rechargeable batteries, if new technology
Does that sound feasible?
“Batteries degrade. They charge less, as they age.”
True for standard batteries. We don’t know about the chemistry this technology. Pumping out the old goo and pumping in new could be equivalent to rebuilding the battery giving it more recharge cycles.
