Lithium polymer (Li-Po) replacement, the Nanotube battery

Everyone agree that battery is the most important part of our digital devices? I think you do. Well, to agreed or not you still have to accept that our devices needs battery to live. Now let’s take a look at the battery we use right now, most of it shaped like this picture on the right, just for the record that picture is a Li-Poly battery for Motorola mobile. It is usually need at least an hour to be fully charged, a couple hours sometimes.

Now, do you ever wish you could charge your cellphone or laptop in a few seconds rather than hours? Researchers at the Massachusetts Institute of Technology (M.I.T) are developing a battery that could do just that, and also might never need to be replaced.

As our portable devices get more high-tech, the batteries that power them can seem to lag behind. But Joel Schindall and his team at M.I.T plan to make long charge times and expensive replacements a thing of the past–by improving on technology from the past.

They turned to the capacitor, which was invented nearly 300 years ago. Schindall explains, “We made the connection that perhaps we could take an old product, a capacitor, and use a new technology, nanotechnology, to make that old product in a new way.”

On top of that, the shape too, will not just be light-weighted, thin, or flexible, it could be made from a paper. It was researchers from Rensselaer Phytechnic Institute, who recently release this latest energy storage technology which dominantly made from cellulose which can be found in papers. Only they fill the paper with nanotube carbon , to used as electroda. As for prove, they have made a battery just a sized of a stamp that can lighten up a small fan or a LED light.
