Han developed a new graphene battery to complete charging in 16 seconds
Stainless Steel Ratchet Buckles
What makes stainless Steel Ratchet Buckles the first-choice for high-end users?
It's the anti-rust advantage as well as its good looking surface.
You don't have to worry about the buckle goes rust even you use it at the sea shore.
It's higher in price though,however everyone who's using it thinks it's worth trying.

At the heart of this new technology is that the new porous graphene material contains a large internal surface area, so it can be charged in a very short time, and the amount of charge is equivalent to that of a normal lithium battery. More importantly, the graphene battery electrode did not show significant loss of energy density after 10,000 charge and discharge cycles.
In fact, research on the manufacture of electric vehicle batteries and accessories using graphene materials has long been known. At the beginning of this year, researchers from South Korea, Case Western Reserve University and the University of North Texas said that their graphene batteries can produce higher than ordinary batteries. Current.
In 2011, researchers at the University of Technology in Sydney also claimed to have developed paper made of graphene, which is lighter, tougher and less dense than steel, and is very beneficial for automotive lightweight research and fuel economy.
