Battery life on smartphones are starting to get better. Manufacturers are starting to squeeze in larger batteries and they’re also coming up with features and solutions that will try to extend a phone’s battery life as much as possible by cutting out unnecessary processes when applicable, although safe to say that we’re still quite far off from having batteries that last days on end.
However thanks to work done by South Korean researchers, they have managed to come up with an interesting technique that could technically help create long-lasting batteries. What the researchers have done is to spray graphene oxide droplets into a hot blend of acid and organic solvent, which is apparently the equivalent of dipping chicken into hot oil. Essentially they’re “frying” the graphene.
The end result can be seen in the image above where the open 3D structure reportedly helps to make the graphene much more efficient and better at transferring electrical charges, as opposed to plain graphene. It should be noted that this isn’t the first time scientists have created 3D graphene, although this frying process should help make it more viable to perform in a mass production setting.
Of course we reckon it will be a while before we actually see the technology and technique applied to consumer products, but in the meantime it is a step in the right direction and hopefully it won’t take too long before we start seeing it being used commercially.
