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.
The paper batteries could meet the
energy demands of the next generation gadgets. A paper battery is a flexible,
ultra-thin energy storage and production device formed by combining carbon
nanotubes with a conventional sheet of cellulose-based paper. A paper battery
acts as both a high-energy battery and super capacitor, combining two
components that are separate in traditional electronics. This combination
allows the battery to provide both long-term, steady power production and
bursts of energy. Non-toxic, flexible paper batteries have the potential to
power the next generation of electronics, medical devices and hybrid vehicles,
allowing for radical new designs and medical technologies.
The various types of batteries followed by the
operation principle, manufacturing and working of paper batteries are discussed
in detail.
