Know what Nanobattery is.

Before I write anything about Nanobattery, let me give you a brief introduction of what a capacitor is, it is an electrical device that can store energy in the electric field between a pair of closely-spaced conductors (called plates). When voltage is applied to the capacitor, electric charges of equal magnitude, but opposite polarity, build up on each plate. Thus a capacitor stores electric charge.
Now coming to the portable electronic devices such as notebooks, cellphones, PDAs and
many others, the major problem with all these devices are that they become useless
after the rechargeable batteries completely
discharge.Unfortunately, the devices themselves have known
huge developments, while their batteries remain a
source of discontent among users. Even the most
advanced laptop can only last for three hours if
relying only on the most advanced lithium
batteries.
NASA has a solution for everything.They came up with a brilliant idea of exploiting the technique used by biological molecules to self-assemble, to achieve the same result.
NASA used the ability of a protein called Ferritin, which contains iron, to perform the task of carrying either a positive or negative charge.
Ferritin has another remarkable ability, being able
to self-assemble more easily to form a homogeneous
layer. Such a ferritin layer could be covered with
another layer of the opposite charge, thus creating
a new capacitor that could store electric charge
between its layers, just like a battery.
The nanobattery has an overall thickness of only a few nanometers and its capacity could be increased even further by adding more layers of alternately
charged ferritin. According to NASA, the practical
applications of this concept would be robust,
stable and would also be easily and quickly
produced.
Well hats off to NASA.
