Elon Musk Announces Tesla's NEW Aluminum-ion Super Battery with 15-min Charging
Elon Musk’s latest announcement could change everything about electric vehicles. Tesla is rolling out an all-new aluminum-ion battery that promises to be a game-changer, boasting rapid 15-minute charging times. The technology has been years in the making, but it could lead to a future where Elon Musk is quite literally, on top of the world. Imagine charging your electric car in just 15 minutes—Elon Musk's latest breakthrough could make it a reality and revolutionize the future of transportation as we know it. Curious to know how this innovation could reshape the EV landscape? Let’s dive into the details.

Imagine me filling up my gas tank in 3.
Advantages - cheaper. Over twice the theoretical energy density.
Disadvantages - less durable than lithium and may have to be replaced more often. But it might only be half the cost to do so.
Spaceship man bad though
Still too long. How fast do they deteriorate?
That’s an improvement but is still a long time. Also, the only thing that could possibly keep up with the demand is nuclear power generation, and ridding spent nuclear fuel cells is becoming an increasingly expensive too. We supposedly own billions in disposal costs as it is.
Are these vaporware like other promised batteries?
Are they less susceptible to thermal runaway?
When everybody’s car has one of these batteries, can the grid handle charging them?
I know the answer to the last one. Nope!
LOL
If people want to buy electric cars, that’s great.
They just shouldn’t be FORCED to buy electric cars.

Currently, the most commonly used electrolyte for rechargeable Al batteries are acidic room temperature non-aqueous ionic liquids (IL) made of aluminium chloride (AlCl3) and 1-ethyl-3-methylimidazolium chloride ([EmIm]Cl). This addressed the initial issue that prevented Al batteries from becoming rechargeable: Al readily reacts to form a passivating oxide coating that is chemically inert and an extremely high potential is necessary to push ions through this layer. This high potential would degrade the electrolyte during recharging. The use of the ionic liquid as an electrolyte prevents passivation and allowed Al batteries to become rechargeable. As mentioned earlier, the active species in the IL electrolyte are AlCl4- and Al2Cl7-.
This electrolyte also faces multiple challenges. In the forefront of those challenges is their sensitivity to moisture. The electrolyte and water exothermically react to form gasses such as H2, Cl2 and HCl which causes cell expansion/distortion and reduction in performance (lower Coulombic efficiency, irreversible decay of capacity). The end result is an unstable cell, safety issues due leakage and corrosion, and more complex and costly manufacturing requirements. Liquid electrolytes have also faced issues such as poor electrode-electrolyte interface.
The voltage and current necessary to achieve a 15 minute fill-up will require massive upgrades to the chargers. Cables will need to be huge. Also, Ultrafast charging generally leads to rapid battery degradation, would be surprised if this battery chemistry is any different.
great...now what ? Infrastructure issues ?
how long to manufacture quantities ? where do you place them ?
for starters, do highway gas stations have room for a few banks of chargers ?
where would the electricity to the starter banks come from ?
I wonder what would be the electric draw from those banks ?
I know, let’s force ‘em to use windmills and solar panels...to see if wind and solar is sustainable...
Can’t we reprocess spent fuel rods into plutonium with breeder reactors? And modernize our nuclear arsenal at the same time?
>>They just shouldn’t be FORCED to buy electric cars
Perfectly stated.
Whoopie!
I Normally just dump my spent fuel rods in the ditch beside the road.
And lighter?
A very valid point. Do gas stations still have the lever to allow you to keep filling up when you take your hand off the nozzle, so you can do your restroom break and such while you fill up? I haven't seen that in forever, but it may just be for my area.
But with the 10-15 minutes I charge at the fast chargers on long trips, I can walk away from the EV while it's charging to go to the restroom, maybe buy a coke, come back and it's usually done. At least, that's with all of the fast chargers on the road trips I usually take. The road trips that have few fast charging options are the ones I would take the gas pickup on. Just being practical about the pro's and con's of each car type without trying to force a one-size-fits-all attitude for either type (like the Dims do).
My take on the video, which I watched about 10 minutes of but it gave me no real details beyond history and hype. Details matter. Are they claiming 15 minutes to charge to 100%? That's worthy of attention, considering that existing batteries slow down charging past 80% or 85%.
Or is it 15 minutes to charge to the usual recommended 80%? Ho hum. I recently took 10-15 minutes to charge to 80% or 85% at virtually every charging stop from Canada to Alabama. Nothing special. Most EV cars (maybe not the EV pickups with the much larger batteries) made in the past few years can do that.
I just did a quick check. This new Tesla aluminum-ion battery is being reported on YouTube. But I can’t find it being reported anywhere else.
Hmm…so it’s wait and see for me.
Imagine millions of gas stations in USA & Canada to fill my gas tank. How many charging stations are there?
Also if I run out of gas on highway, all I need is a gas container filled with gas easily obtained from nearest gas station.
If my EV battery dies on highway, I will need to call a motorized charging service to come to rescue.
And we shouldn’t be forced to pay taxes that subsidize play toys for the rich!
