ok, I can wrap my head around liquid battery
Can you wrap your head around massive fossil fuel power plant construction to supply all the cheap electricity needed for the very impractical pipe dream of an electric vehicle that is as good as a gasoline vehicle?
Can you spell c o a l ....
Sure. And the cost?
Maybe you just open a valve and drain the toxic waste onto the ground before pumping more of the chemical into the cells. After all, toxic dumping is needed to provide clean energy for the children.
I’ve also tried that.
I took a fully charged battery, dumped the electrolyte. Took freshly purchased, properly mixed electrolyte and poured to proper level in each cell.
The battery was stone dead. It would not take a charge.
I did this as an experiment to see if regular electrolyte changes would increase battery life, considering new electrolyte is so cheap.
The good news here is that they(engineers) are attacking the right problem with EV’s and that being the stupid long recharge times. Range is not the problem. The recharge times was always the issue for me.
So, refueling would be like doing a drive through quick oil change. Sounds expensive and labor intensive unless the vehicle is designed with standardized ports for such a thing, and then you’d have to build the infrastructure, all the “oil change” shops.
is the liquid toxic? recyclable? battery life?
I have seen some batteries like this demonstrated but they had toxic liquids that had to be treated as hazardous waste. The other issue was there was an anode that decreased performance exponentially till it has to be replaced.
The anode in the battery I saw was platinum.
Digging through the links in that article shows that the chemicals needed have two major problems.
One problem is that the primary chemical is extremely expensive and unlikely to get any cheaper.
The second problem is that is a heat store and not an electricity store. The elements get as host as 400°F.
They'll mix it with cow farts and sell it to tourists from outside the Milky Way.....
“I took a fully charged battery, dumped the electrolyte. Took freshly purchased, properly mixed electrolyte and poured to proper level in each cell...The battery was stone dead. It would not take a charge.”
LOL, but don’t forget, reports like this one DRIVE POLICY, even though the reporters have NO CLUE regarding how they’re being hoodwinked, since it’s about, yuck, ‘technical stuff’, yuck. After all, they didn’t become ‘reporters’ because they were good in math and science.
Should have tried Brawndo!
I'd be interested in seeing the solution, because they'd be trying to pump in an electrically charged liquid (probably without having it in contact with air, btw) that doubles as something that would dissolve flesh (and tires, probably). It would be *at least* as complicated as hydrogen pressurized refueling.
The notion is similar though -- with either one, the hydrogen or electrolyte would be recycled at the station, for reuse by later customers, and using electricity -- no delivery vehicles. And the speed and convenience of hydrocarbon fuel fillups (gasoline or diesel). Actually, more convenience, because liability concerns would likely mean a return to the good old days of the friendly neighborhood guy in a hat coming out from the building to fuel one's vehicle.
That's the free market at work.
I’m glad you got a charge out of my comment.
That system is apparently equating a battery refill to a gasoline refill. OK, what about safety? Spill a little gasoline, so what. Just mop it up.
Spill electrolyte, be it acid or alkaline based, and you have a serious corrosion/burn issue if not a fire issue. Not to mention toxic fumes.
You are right, mindless crap like this drives policy. The loonier the more the loons cling to it.
About 20 years ago Robert Hockaday was working on a small, refillable methanol-based fuel cell, with a view to making portable phones instant-refill, eventually working out into vehicles and such. Manhattan Scientifics supported his research, but it didn’t bear fruit, and they parted ways.

Looks like he’s invented something a little less world-changing:
