New discovery could lead to long-lasting smartphone batteries

Researchers in Glasgow have worked out how to manufacture graphene in a more cost-effective manner, meaning our smartphone batteries may last much longer.

Graphene is a super-thin and super-strong conductor, meaning it could do wonders for our smartphone batteries. Batteries could have more capacity than they do currently, and would only need to be charged once a week.

But, until now, it has been expensive to make. Researchers at the University of Glasgow found a cost-effective way to make graphene, which means it may be powering smartphones sooner than expected.

To get into the technicalities for a moment, graphene is usually made by a process known as “chemical vapour deposition.” This combines gases in a reaction chamber to result in a film of graphene being deposited on a surface known as a substrate. The Glasgow researchers used a similar process, but created graphene on the surface of commercially available copper foils.

This is not only an excellent medium for the graphene to form on, but is more than a hundred times cheaper than existing production methods.

This could have a more widespread impact too. Not only could it mean advances in smartphone batteries, but it could be used in superfast computing and advanced prosthetics.

Graphene could help our smartphone batteries live longer, but much more work needs to be done before it’s a reality.
