Batteries are a vital tool to our everyday lives. With technology
rapidly expanding by the day, researchers in battery technology are
continually exploring different ways to make batteries. There is now more
then ever, an expanding array of technologies that need batteries to power
them. There are numerous types of batteries that have been developed for
electric cars and more powerful portable devices. Size, short range,
environmental issues and high expense are all problems to be solved for
these new endeavors. Cutting edge batteries that show promise for electric
vehicles are sodium sulfur, lithium ion sulfide, zinc chlorine, and nickel
metal hydride all seem to show promise. Solar batteries are another kind of
cell technology. They produce electricity by a photoelectric conversion
process. Electricity is made from a photo sensitive semiconducting
substance like silicon crystal. It s functions by light hitting the crystal
causing electrons to be dislodged from the surface of the crystal. These
electrons then move to an opposite surface. They are then collected as a
currant of electricity. Solar batteries have the advantages of long lifetimes.
They are used in space to provide electricity for operation of equipment
abord spacecraft s.
Research is currently being done on the possible use of organic
polymers and solid inorganic conductors as electrolytes. New materials for
the use of both positive and negative electrodes is also being researched.
Batteries play a very important role in our everyday lives. Many different
devices we have come to reply upon require batteries to supply them with
the power they need. Advancement in battery technology are working to
reduce environmental hazards caused by batteries and to make them more
compact.
The battery is a true universal source of energy that is used around the
