Storage of electrical energy is very important in many applications especially electrical appliances which require mobility or short burst of energy over a short duration of time. There had been many technologies developed to emulate characteristics of an ideal power supply which can store large amounts of energy, providing good power output as well as being able to be charged and discharged rapidly without deterioration of any type. A typical power storage device can be characterized by its power density and its energy density, noting that with our current technology, none which can achieve the best of both.
A battery is a device that converts energy into electricity by storing electrical energy thru chemical reactions. In a battery, there are three major components . The first component of a battery is a terminal called anode which is an electrode through which electric current flows into . The second component of a battery is a terminal is called cathode which is an electrode through which electric current flows out . These two terminals can be found at each end of a battery. The third component of a battery is called the electrolyte which is an ionic compound(s) that are used to separate these two terminals, send electrons and used to neutralize charges that build-up in the chemical reaction processes .

These reasons are why Lithium-Ion Batteries are some of the most viable options when designing new gadgets. But, the structure of these batteries are why these batteries are being used for new gadgets. A Lithium-Ion Batt...
The first battery construction was described as: “place copper plated in an earthen pot, cover it with copper sulphate and wet saw dust. Spread Zinc powder and cover it with mercury. Due to chemical reaction a positive and negative charge is created. The water is decomposed into oxygen and hydrogen.” (2) This battery did not create very much voltage and certainly did not hold a charge for any length of time.

This battery does have a couple limitations such as circuit protection to maintain voltage and current levels. Also, when this battery is not in use it still continues to age. It has a limited number of life cycles until the battery starts to lose capacity. Lithium-ion batteries are also more expensive to manufacture when compared to other batteries on the market.
The future is, however, inherently murky. Fuel cells still face significant technological, political and economic hurdles before they can realize their truly awesome potential. An examination of these hurdles, set to the backdrop of an explanation of the current state of the art in fuel cell technology and the current and developing economic and regulatory landscape, will provide insights into much touted future of the fuel cell. In the near future, the fuel cell will come to play a much more prominent role in the world energy economy. The extent to which this innovation will revolutionize the world will depend on any number of technological, economic and political factors.
Batteries where the chemicals cannot be returned to their original form once the energy has been converted (that is, batteries that have been discharged) are called primary cells or voltaic cells. Batteries in which the chemicals can be returned to its original form by passing an electric current through them in the direction opposite that of normal cell operation are called secondary cells, rechargeable cells, storage cells, or accumulators.
