How do you keep these from becoming bombs? Either accidental or intentional? Any time you put large amounts energy, in a form that can release it almost instantly, you have the potential for large scale damage. Imagine these in a Tesla. First how well would they hold up to a crash? As dangerous as lithium ion batteries are in a crash/fire: how dangerous would something be that could release its energy at 10/100 times the rate? One of the things that scares first responders is cutting into electric or hybrid vehicles. Wouldn't the danger increase? Are these more or less susceptible to cascading failure? In a battery bank, as one battery catches fire or explodes, what happens to its neighbors? Time to design with known issues in mind.

I think you should do an episode on Thorium Molten Salt Reactors.. They have a lot of benefits compared to current energy production methods.

There is no substance made that is stronger than steel. That's why we make skyscrapers and mega structures out of steel and not graphite. Graphite will crunch and crumble like gram crackers before the first wall could go up.

Those numbers look good though, on paper, but not in reality.

There is no stopping inovation. But the time scale it takes from innovative technology to a market ready proposition is indeterminable. I am now an old man. I was quite a young man when nuclear fusion would be a practicable source of electricity generation. Ten years or so said the pundits.,That was more than forty years ago and current prediction is - guess what, ten years from now.

Cool. Sounds promising.

sounds awesome, but (ive no clue of electricity) 100wh per kg sounds scary^^, what would an explosion of these things looke like? :o

I feel like there will be a point in the future where batteries and capacitors will be functionally the same thing.
Adrian Nel
There is a startup in Japan developing a very niche,very expensive super EV that will use batteries combined with caps

Good job......again👍

ultra capacitors is definitely the future.. even elon thinks it is

Space elevator anyone? Right? Scifi but real? Future but now? Wtf why isn't this done. I'm pretty sure I read Arthur c. Clarke bitch about this, only he was mad mankind hadn't got around to creating some something that cool. No excuse, now, humans. Get off your collective taints, and do that.

Great videos, well prepared and informative as well as being positive. Very exciting times - I work in carbon composite graphene cathode research and things are moving so quickly now. Just hoping that the lithium lobby does not suppress the upcoming technology, those were old tactics for the world that was.
SargeantPrepper
Maybe future Evs should be a lithium ion battery/super capacitor hybrid, where the capicitor is used for regenerative braking and dc fast charging, while lithium batteries are used for long range driving and lower levels of charging.

Imagine the handle of a charger able to charge Tesla in 5 seconds when one for supercharging for half-hour looks like a fist.
William Hughes-Games
Ultra capacitors are great to extend the life of batteries which are degraded by extreme levels of charging or discharging or high rates of charge and discharge. The ultra capacitors can take up fast levels of charge such as when braking in an electric car. The charge can then either be used to slowly charge the battery or to accelerate the car when needed.

My dad told me before i was born, they were talking about graphene batterys already. Im 14 now and nothing -_-
Muhammad Bilal
The founder of estonian company you talked about said ultra-capacitors are not going to replace batteries. This video basis is totally wrong.
Jean Labrek
_ It would be easy to get free energy if possible to convert (capacitor static stored electriciy) to a battery without frying it or the wires _ as a Whimhurst on a small windmill can store a lot of static, and a battery can drive an electric motor ?
RHIANN GACUSAN
the problem with this battery is THEY REQUIRE CHARGING, the energy cell of the future does not require charging and is disposable. UNTIL I HEAR OR WATCH A CAR OR ENGINE THAT COULD RUN 24 / 7 HRS FOR 20 YEARS WITHOUT CHARGING it is not yet the future.

What is graphene? What is it used for? The most amazing thing about this semi-metal of the future is the fact that you can produce it yourself in your living room!

What is graphene, and why is it so amazing? One of the things that makes graphene so cool is that it’s the thinnest material you can imagine. It's just one atom thick! This means this material is mathematically 2-dimensional. And you can still hold this single layer of atoms in your hands!
Surprisingly, graphene isn't a unique or rare substance. In fact, it has the same carbon structure as the graphite you use every day when you draw or write with your pencil! But at the same time, in 0.03” of graphite, there are about 3 million graphene layers!

SUMMARY:
- Graphene isn't a unique or rare substance. In fact, it has the same carbon structure as the graphite you use every day when you draw or write with your pencil! But at the same time, in 0.03” of graphite, there are about 3 million graphene layers!
- Dr. Konstantin Novoselov and Professor Andre Geim discovered the wonder-material in 2004 at the University of Manchester. They were examining how efficient graphite is as a transistor. The story goes that graphene appeared thanks to sticky tape!
- Graphene used to be incredibly expensive to manufacture. It cost a whopping $1,100 to produce enough graphene to cover the head of a pin. However, by the end of 2015, you could buy 0.35 oz of graphene for $1,000.
- Graphene is incredibly stretchy. It can stretch as much as 25% of its length! This material is also really stiff. Actually, it’s the hardest material people know about — even harder than diamonds, and that says a lot!
- One more great thing about graphene is its relationship with electricity. This material carries electricity more quickly, more precisely, and more efficiently than any other known material.
- Graphene may be the answer to the water crisis many countries are facing. If we make membranes from graphene, they would be able to let water through while filtering out salt at the same time.
- One layer of graphene is impressive enough. Can you imagine what you could achieve with 2 layers of this super material? Nothing short of incredibly strong body armor.
- If producers start to use graphene in gadget manufacturing, we might end up with smartphones that can be bent in any direction. One of graphene’s main properties is its flexibility.
- Graphene can be used in the beauty industry as well. It will be the perfect alternative to current hair dyes, most of which are still toxic and damaging to hair.
- Well, you can potentially make graphene at home, provided you have enough time and patience to do so.
