Life Of Battery
Even if never taken out
of the original package, disposable (or "primary") batteries can lose
8 to 20 percent of their original charge every year at a temperature of about
20°–30°C. [54] This is known as the "self-discharge" rate and is due
to non-current-producing "side" chemical reactions, which occur
within the cell even if no load is applied to it. The rate of the side
reactions is reduced if the batteries are stored at low temperature, although
some batteries can be damaged by freezing. High or low temperatures may reduce
battery performance. This will affect the initial voltage of the battery. For
an AA alkaline battery this initial voltage is approximately normally
distributed around 1.6 volts.
Paper Battery
Energy has always been
spotlighted. In the past few years a lot of inventions have been made in this
particular field. The tiny nuclear batteries that can provide energy for 10
years, but they use radioactive elements and are quite expensive. Few years
back some researchers from Stanford University started experiments concerning
the ways in which a copier paper could be used as a battery source. After a
long way of struggle they, recently, concluded that the idea was right. The
batteries made from a plain copier paper could make for the future energy
storage that is truly thin.
You can fold it in different shapes and
forms plus it as light as feather. Output voltage is modest but it could be
increased if we use a stack of papers. Hence the voltage issues can be easily
controlled without difficulty. Usage of paper as a battery will ultimately lead
to weight diminution of batteries many times as compared to traditional
batteries.
Properties of Carbon

(Greater than Steel).
• Low Mass density
& High Packing Density.
• Very Light and Very
Flexible.
• Very Good Electrical
Conductivity (better than Silicon).
Abstract
The Batteries form a significant part of many electronic
devices. Typical electrochemical batteries or cells convert chemical energy
into electrical energy. Batteries based on the charging ability are classified
into primary and secondary cells. Secondary cells are widely used because of
their rechargeable nature. Presently, battery takes up a huge amount of space
and contributes to a large part of the device's weight. There is strong recent
interest in ultrathin, flexible, safe energy storage devices to meet the
various design and power needs of modern gadgets. New research suggests that
carbon nanotubes may eventually provide the best hope of implementing the
flexible batteries which can shrink our gadgets even more.
Carbon Nanotubes
Carbon nanotubes (CNTs)
are allotropes of carbon with a cylindrical nanostructure. Nanotubes have been
constructed with length-to-diameter ratio of up to 132,000,000:1, significantly
larger than any other material. These cylindrical carbon molecules have novel
properties, making them potentially useful in many applications in
nanotechnology, electronics, optics, and other fields of materials science, as
well as potential uses in architectural fields. They may also have applications
in the construction of body armor. They exhibit extraordinary strength and
unique electrical properties, and are efficient thermal conductors.
Conclusion
One of the major
problems bugging the world now is Energy crisis. Every nation needs energy and
everyone needs power. And this problem which disturbs the developed countries
perturbs the developing countries like India to a much greater extent. Standing
at a point in the present where there can’t be a day without power, Paper
Batteries can provide an altogether path-breaking solution to the same.
