Samsung is working on a graphene battery that charges five times faster
While I have to say that I am not at all complaining about charge times of smartphones, it apparently needs to be faster. Samsung is working on a graphene battery that has more capacity than current batteries and can be charged five times as fast.
The Samsung Advanced Institute of Technology (SAIT) announced this today, reports ZDNet.
Graphene has long been seen as a promising material to replace the current lithium-ion batteries. Samsung Electronics' research arm has successfully synthesized a "graphene ball" that can be used to make lithium-ion batteries last longer and charge faster, the company has said.
According to Samsung, the technology could provide a smartphone battery that is fully charged in 12 minutes. The capacity could also grow by 45 percent. According to Samsung, the battery remains stable up-to 60 degrees Celsius and could therefore also be used in electric cars.
It is unclear when Samsung expects to start mass production of the battery.

Be great for electric cars and buses, or hybrid petrol electric vehicles.

As someone who has put a lot of research into graphene, I am legitimately excited and sincerely hope Samsung succeeds in finding a cost-effective way to mass-produce graphene batteries. The faster charging is merely a side effect of the many miraculous features of graphene. I personally will not buy an electric (or hybrid) car until one comes with a graphene battery, assuming it doesn't cost as much as a small house. But as soon as one is available, I'm going to be first in line.
Looking at the diagram, it looks like their graphene is very impure, which I find discouraging. It's supposed to be 1-atom thick, so the fact they show it being thicker than the cathode and substrate while also being lumpy isn't a good sign. But, even if it's a third as good as it should be, it's still way better than Li-Ion could ever be.

This is not just about phones...
Imagine the future:
- Self driving cars, trucks, buses, etc.
- Walking robots ( think Atlas or Big Dog )
- Transport pods that go on a pipe (or in it !?)
- Flying machines ( drones ) that could go for hours before charging, they would just land on a charging station 10 minutes and go back in air for more hours
- Other portable/wearable devices that could charge ultra-fast when close enough to a power source
The idea is that at some point we'll simply forget about charging. Devices and vechicles will charge by themselves wirelessly (or by shallow contact) when close to power sources without the user ever having to worry about "plugging them in".
To make this future possible we need new battery tech... which, to be honest, currently it SUCKS. Low capacity/volume or weight, prone to exploding, unstable, doesn't last long...
Fossil fuels have 10 times higher power density than current batteries, no wonder electric cars aren't yet mainstream.

For twenty years its been graphene this and that....
Still not one product.
I'll believe this hype train when they have a WORKING prototype. And its independently confirmed.
Until then it's pure BS Samsung.

I know, i have zero complaints with how fast my LG G6 charges with a fast charger.
Bought a $9 charge stand for it, plugged it into my fast charger and it's awesome. Almost as nice as wireless charging.
This could be good for laptops and tablets I think.
