Latest Invention: World's First Battery Powered by Paper


Sony has recently announced it managed to come up with a battery powered by paper. However, the whole process is more complex than simply using a standard paper.

The batteries developed by the Japanese tech giant make use of enzymes in order to break down the glucose found in the cellulose of the paper (which by the way is made of wood pulp fibers).

It would be interesting to note that Sony was able to demonstrate its bio-battery. The demo took place at the Eco-Products exhibition in Tokyo. During the presentation the paper was placed into a mix of water and enzymes. After a couple of minutes the liquid started generating enough power to activate a small fan.

After enzymes broke down the paper, they were left with sugar that was produced from cellulose. Then they were able to process the sugar to produce hydrogen ions and electrons. The latter then went through an outer circuit to produce power. Mixed with oxygen in the air, the hydrogen ions were then able to create H2O.

"This is the same mechanism with which termites eat wood to get energy. Bio batteries are environmentally friendly and have great potential as they use no metals or harmful chemicals," explained Chisato Kitsukawa, a PR manager at Sony.
