Graphene technology is, without a doubt, the best mobile battery innovation to emerge in the 21st century. Not only do graphene batteries hold up to 20% more energy than a lithium-ion alternative of the same size, they also generate far less heat while charging. Consumer products packing this next-generation tech are still quite rare, but you can be one of three lucky winners to own a Chargeasap Flash portable power bank crafted with graphene cells. Here's what you need to know. Read More
Graphene has been dangled in front of us for over a decade as a new, magical material capable of solving all our technical problems, while steadfastly staying out of consumer products. It's a materials science fact with the mythos of science fiction, but it's finally percolating down into stuff you can actually buy, like this portable charger/battery. Made by a Chinese company called Elecjet, the Apollo Max promises 37Wh (10,000mAh) of capacity, 100W charging, 60W discharging, and a 19 minute recharge time. Unfortunately, that last claim is just science fiction. Read More
Graphene is an amazing material. How amazing? Graphene is composed of a single layer of carbon atoms joined in a hexagonal lattice – it's incredibly strong, light, highly conductive, and nearly transparent. It has been put forward as the key to advancing everything from flexible displays to semiconductors that can save Moore's Law. For all that promise, graphene is still rare in consumer applications due to the difficulty in producing it. Samsung's Advanced Institute of Technology might have finally found a way around that.
Pure graphene was first isolated in a remarkably low-tech way back in 2004. A bit of scotch tape was used to pull a layer of carbon atoms off a larger piece of graphite, and boom – a 2D sheet of carbon, which we now call graphene. Read More
