Sony’s New Bio-Battery Runs On Sugar

August 23, 2007

Sony have developed a bio battery that generates electricity from sugar.

Test cells of this bio battery have achieved power output of 50 mW, currently the world’s highest level for passive-type bio batteries. The output of these test cells is sufficient to power music play back on a memory-type Walkman.

It is done by breaking down sugar to generate electricity that involves efficiently immobilizing enzymes and the mediator (electronic conduction materials) while retaining the activity of the enzymes at the anode.

Sugar is a naturally occurring energy source produced by plants through photosynthesis. It is therefore sustainable.

If Sony manage to develop this further, producing a usable alternative for current batteries, this could have a variety of applications.
