Superfast-charging aluminum-ion batteries outpower lithium-ion
NewAtlas ^ | May 18, 2021 | loz-blain

Australian company Graphene Manufacturing Group (GMG) has announced exciting performance test results for a new type of aluminum-ion battery that can charge 10X faster than today's lithium-ion units, while lasting much longer and needing no cooling.

Does that mean an unintentional discharge would also be more catastrophic?

Nice work and it looks correct to me.

I am always cautious and skeptical of claims from companies that are looking for investors.

However, there are a lot of smart people pushing for new battery technology as we speak and there have been some promising developments in the past decade. While most of them are based on big promises, we are moving toward much more efficient batteries that hopefully will not rely on lithium and other rare earth metals (cost) with improved capacity.

It will happen eventually. The company that makes the breakthrough will be among the wealthiest in the world pretty quickly. The capitalist incentive in this market is big.

Agree, this sounds interesting. I see the first widely commercial deployment “hurdle” as laptop batteries. If it can break into that market significantly, the next market would be the golf cart type application from a volume perspective. After that, replacement for existing gas/diesel batteries and then perhaps electric cars.

They should scale this up to 18650. Extrapolate those numbers . . .

If most people drive less than 100 miles a day, the routine for charging an electric vehicle will not normally involve a trip to a charging station. If the owner has a Level 2 charger at home, they can start the next day with a full battery from an overnight charge. It’s going on longer trips, that will call for a stop at a commercial charging station. As you suggest, there are practical limits which will always prevent an EV from recharging as fast as one could fill their tank with gas. The need to accommodate a driver who must wait half an hour or more for a recharge will inevitably make these charging stations wholly different from a gas station. Beyond merging a charging station with a restaurant, like an IHOP, I cannot imagine what the diversions will be.

That's why I've always thought carrying around a fixed battery pack in the vehicle was idiotic. They should be removable, placed underneath so they can be swapped out at a facility like a drive through car wash with a credit given for remaining charge.

Just pull in, have a machine swap the battery, and drive out.

i fill my tank and go 400 miles. What is that, like 600 km?

I've always been an advocate for Hydrogen Fuel Cell vehicles, with an auxiliary battery for braking regeneration storage.

Hydrogen is not a fuel, it is an electricity storage medium.

It is 643 km.

I see modern electrics as a great SECOND car for people that live in urban or suburban environments, or “only car” for the college kids that just need something to get around the urban area in which they live. And the could use small three wheeled electrics to really save, not to mention park easily. It becomes a bicycle/scooter replacement.

For me, it will start to become real if they can just do AA AAA and C recyclable batteries.

If and when a hydrogen distribution system can be introduced, fuel cells are just a curiosity. But fuel cells are a much superior method of providing the current flow necessary for electric vehicles to operate, if the problems of refueling and storage can be worked out.

Hydrogen is a highly reactive and mischievous element to work with, being highly inflammable, and has a nasty habit of leaking out just about every coupling where there is joint that must be sealed. Because it is not compressible into liquid form until a very low temperature is achieved, it must always be handled as a gas, which means rather bulky storage units, even at very high pressure.

Manufacture of hydrogen is by various means, all of which involve a sizable input of energy, not all of which may be reclaimed by today’s processes. One of the simplest is electrolysis of water, which also produces one volume of oxygen for each two volumes of hydrogen. But it takes plenty of CHEAP electrical energy, produced by another means, to make this process economically feasible.

The other means of generation of electrical power is nuclear - not the older uranium-fueled light water plants, but a newer and much more manageable thorium-fueled molten salt plant, which has almost none of the drawbacks of a uranium-fueled plant. Widespread adoption of thorium-fueled molten salt atomic reactors would assure an adequate flow of baseline energy demand on a 24/7/365 basis, at lower cost and with less environmental impact than almost any other energy source.

The modern charge standard is not 480v it’s 800 volts BMW, Porsche, KIA, and VW already have vehicles that can use the 800v standard. To fully charge 82kWh in 5 mins would take 1200 amps DC which sounds like a lot but your avg diesel starting motor draws well over a 1,000 amps at 24v and those cables are air cooled not much thicker than your thumb. The 800v standard uses liquid cooled cables and would be of similar thicknesses. The next standard after 800v will be 1200v DC polycarbonate and silica insulation at those voltages is a few tens of MM thick the plugs are black when plugged in they are fully two-way digital communication for the charger negotiation protocols only when the plug is fully seated and liquids flowing and ground safety verified would current be allowed to flow. The process is an order of magnitude safer than a user manually pouring flammable liquids into an open container hole with vapors leaking out of said opening. It is impossible to be shocked by a DC fast charger the whole cord is off line until a complex handshake happens and if you were dumb enough to pull the plug which is locked in my a magnetic lock I might add in a millisecond the charger senses the break in continuance and cuts off the DC current simply put you cannot be shocked even with willful user error or malfeasance.

The current 800v standard is for 350kw charge rates. The avg nuclear plant is 1,350,000 Kw per reactor Texas has two such plants with four reactors two at each plant with the plant sized for four reactors each for a total of eight.

Each reactor could run 3857 chargers at 350kw each there are 4 of them so over 15,400 fast chargers just on those four reactors alone. I’m in the Texas power industry Texas has 125,000 mega watts of installed capacity with an avg summer capacity of just over 100,000 mega watts. 100k mega watts is 100,000,000 kw theoretically Texas power industry could simultaneously run over 285,000 fast chargers all at once.

As for current to the chargers commercial services to the local transformers are 15,000 volt three phase AC to drive a single 350kw Three way rectified charger would take 7.7 amps @15000v from each leg of the triple phase AC supply. Ten of such chargers would take 77 amps. Medium duty poles are rated for 7200 to 34500 volts three phase. 15,000 is just the most common. A typical power line of bare aluminum conductor will be rated at 100 amps each phase more than enough to drive ten chargers which is also the avg number of pumps at a service station. Going to dedicated HV lines to a sub station is an option with HVAC being 34500 to 500,000 volts three phase ratings.

It will have to match my V8 truck motor and recharge in an hour or less.

They can stick their electric vehicles otherwise, no matter how expensive these commie a$$ hats in Washington make the gas.

“Yep, that’s gonna work out well, oops the power went out again...”

The solution would have to be a battery on the delivery side so it can slowly pull from the grid.

The question was for a Tesla. Those vehicles you listed have 800V battery packs, which is perfectly suited for 800V charging without lossy and expensive DC-DC converters. Teslas cannot charge at 800VDC.

Teslas use 375V battery packs, and their Supercharger is 480VDC.

Here's a battery solution that has the problem that Alec Guinness had in "The Man In The White Suit" Nano Diamond Battery Comes with a radiation scare.
