Powering Phones, PCs Using Sugar
The battery is an enzymatic biofuel fuel cell – a type of fuel cell that uses a catalyst to strip molecules from molecules of a fuel material.

A team of researchers at Virginia Tech University have developed a battery with energy density an order of magnitude higher than lithium-ion batteries, while being almost endlessly rechargeable and biodegradable as well – because it’s made of sugar.
The battery is an enzymatic biofuel fuel cell – a type of fuel cell that uses a catalyst to strip molecules from molecules of a fuel material. Instead of using platinum or nickel for catalysts, however, biofuel cells use the catalysts made from enzymes similar to those used to break down and digest food in the body.
Sugar is a good fuel material ...
