Sony has at the Eco-Products 2011 trade show in Japan a flat battery demonstrated that the energy paper. An A4 would ultimately provide for a capacity of 18Wh can provide and the battery is for christmas cards to use.
The bio-battery using a cellulase enzyme for paper to break down to glucose. The glucose can be used as fuel for the battery. The anode of the battery set with the help of enzymes, the glucoseoplossing to, so that electrons and hydrogen ions are formed. The hydrogen ions and electrons to migrate separated to the cathode of the battery. By the displacement of the electrons through the external circuit, the battery can generate electricity.
The battery is based on an earlier version that glucose can convert into electricity. Sony has, however, the efficiency and the size improved. In theory the battery will eventually have a capacity of 18Wh can offer with the amount of glucose of an A4 sheet. Provisional is the capacity, however, is much lower, says Sony at the Japanese site Tech-on.
Sony demonstrated the technology at the fair with a christmas card. As soon as the receiver is a liquid over the map pour, this a song to play.
