Your intestines inspired this next-gen smartphone battery

These finger-like protrusions, each about a millimetre long, massively increase the surface area of the intestine, making digestion way more efficient.

Now, a team of Chinese and British materials scientists have used exactly the same principle to make batteries way more efficient.

"It's a tiny thing, this layer, but it's important," said study co-author Paul Coxon from Cambridge's Department of Materials Science and Metallurgy.

So far this is just a proof of principle, so it'll be a while until lithium-sulphur batteries become commercially available.

There are other issues to solve before that happens too - lithium-sulphur batteries still don't last as long as lithium-ion batteries.

The keyword there is "rumors", however, as very few of those reports are citing trustworthy sources.
