Sugar-based battery touted

50 milliWatts delivered, Sony claims

Sony says it has created a battery that produces electricity by breaking down sugar. The bio cell, which measures 39 cubic millimetres, delivers 50 milliWatts.

A video provided by Sony shows four of the cells connected in series delivering enough energy to power a Walkman music player. The battery uses glucose solution as a fuel.

As in other cells, power is produced through a flow of electrons between a cathode and anode.

In the bio cell, sugar-digesting enzymes at the anode extract electrons and hydrogen ions from the glucose. The hydrogen ions pass through a membrane separator to the cathode where they absorb oxygen from the air to produce water as a byproduct. The electrons flow around the circuit outside the device producing the electricity needed to power it.
