Seems very interesting. How ever I feel like this would destroy your battery in some manor, but I could be wrong. I will be getting one of these when they are released (as long as they don't cost over the £50 mark)
I remember reading about this before, the video kinda takes the original context away. I believe this particular prototype uses a completely new type of battery based on graphene; and actually has more charge/drain cycles than typical Lithium ion batteries, the insane charging speed is a perk from using the new battery type.
This would require a totally different battery type, it would need to act more like a capacitor as they quickly fill and discharge. I'm not sure li-ion batteries are capable of that.
I hate how people like to act as if they came up with the idea by themselves... the girl got the idea from other's research projects that work in the University:
However, their inventions are worthless since 2 russian hackers by mistake discovered graphene:
