Skeleton and KIT promise graphene SuperBattery with 15-second charging
Estonia’s Skeleton Technologies and Germany’s Karlsruhe Institute of Technology have partnered up to complete development on what they’re calling the SuperBattery for EVs – “a groundbreaking graphene battery with a 15-second charging time.”

Will be useful for small items such as phones etc. but useless for EVs because the current limitation in the speed of their charging is the inability of the supply system.

Yeppers. Seems to get ignored a bit by the fanbois.

Lifetime? Number of cycles until it fails?

Its a hybrid of lithium and supercaps and lasts for hundreds of thousands of cycles without degrading
Supercapacitors, or ultracapacitors, store charge statically instead of in a chemical form, so they offer enormous power density, charging and discharging at vastly higher rates, and last for hundreds of thousands of cycles without degrading. The flip side here is that their energy density is terrible compared to lithium; to hold the same amount of energy you need a battery pack many times bigger than a comparable lithium pack.
The solution, as has been proposed before by companies like Nawa – and which many believe underpins Tesla’s acquisition of Maxwell – is to put together a hybrid energy system with a mix of lithium and supercapacitors. The lithium gives you long-term, high-density storage, while the capacitors give you high power outputs, the ability to work across a very wide range of temperatures, and super-fast charge capability, not only at the charging station but also when it comes to harvesting energy through regenerative braking.
A hybrid lithium supercapacitor graphene based super battery.
A bit like that powercube in stars wars that Qui-Gon Jinn hands to Anakin Skywalker.
Not really, but getting there.

I think they need to find another option for batteries. Something completely new.

Sibeen doesn’t watch movies I’m afraid.

I watched on last night and I quite enjoyed it, thank you very much!

NHOI. Which is surprising since I am a bit of a movie buff and it was both praised and made a bit of money.

Does this mean I’m ahead of the forum curve when it comes to recent movies?

Let me conduct a T-test…

you’re in front of Bubblecar.

closest i have is 2018 Arctic, which was good.

Hmm. I think we’re past that now, in much the same way as we’re past car engines using something other than reciprocating pistons.
Lithium has highest energy storage per unit weight (excluding internal combustion). So for anything mobile, lithium and its variants (including nanotechnology and bolt on supercapacitors) are the way to go.

They could be charged in smaller banks that the supply could accommodate. Then the total charge time might be many minutes instead of many hours.
To put this into some form of perspective to charge even the cheapest Tesla model 3 with a 54 kWh battery and to do it in 15 seconds means you need to be pumping in 13 MW of power. The Tesla supercharger uses 480 volts so around 27 kA will be flowing. You’ll need a forklift to move the cable to your car.

Still, the coal mining industry runs draglines by extension cables.
Draglines are huge, as is the diameter of the extension cord…

sort of nuts when people start talking about charging large batteries in fractions of a minute, seconds, or even many minutes really
there’s enough problems already with toasters and kettles in the mornings, or of the evenings imagine people plugging their electric cars in when they get home, be overhead power lines hanging down to the ground, glowing orange
I guess if everyone has solar and batteries on their houses be some compensations, if everyone goes to home inverter power (batteries) of the night probably be able to run lower mains voltage, who cares about some poor bastard down the end of the street still on mains only running incandescent bulbs, they can get their candles out
