Improved mobile batteries promised thanks to fungal breakthrough

Smartphone battery life could soon be getting a boost thanks to the use of bread mould, with an innovation developed at the University of Dundee allowing for this unusual combination.

The use of material based on fungal growth could mean that batteries are more stable and sustainable, thus able to hold more charge for longer periods, according to research spokesperson, Geoffrey Gadd.

Current smartphone batteries combine an electrolyte, anode and cathode. And rather than reinventing the wheel, a number of research teams have been working on ways to replace the current materials used for these components to enhance performance.

Gadd said that bread mould would make an appropriate stand-in for the combination of chemicals used in batteries at the moment, according to a report published in Current Biology.

The reality is that such technological advancements get announced when they are a long way from reaching commercial viability. And in recent weeks, there have been a flurry of similar claims from other academic institutes across the world.

That is not to say that smartphones of the future will not be endowed with better batteries, but rather that bread mould might not be the solution that manufacturers choose.
