Each cell inside a battery consists of a liquid, paste or solid "electrolyte," a "positive electrode," and a "negative electrode." The electrolyte is an ionic conductor; one of the electrodes reacts, producing electrons, while the other accepts electrons. When the electrodes are connected to a device to be powered (called a load) an electrical current flows. ("Battery," 2007) As an example, in one cell of a lead-acid battery used in automobiles, the process producing the current takes place as follows:

One plate inside the cell is made of lead; the other plate is made of lead dioxide, and it contains a strong sulfuric acid electrolyte in which both plates are immersed.

Lead combines with SO4 to create lead sulfate (PbSO4) plus one electron.

Lead dioxide, hydrogen ions and SO4 ions, plus electrons from the lead plate, create PbSO4 and water on the lead dioxide plate.

As the battery discharges, both plates build up PbSO4 (lead sulfate), and water builds up in the acid. (Brain, 2007)

The reaction can be reversed by applying current to...

Conclusion: As we saw in this paper, batteries provide us with power by converting chemical energy into electricity. They are used in almost every commonly used device such as cars, computers, cell phones, and MP3 players; hence battery is one of the most useful inventions ever made.

It was used by Michael Faraday in the 1800s in his experiments on electromagnetism. Other inventors improved on the battery's original design and these improvements produced telegraphs and doorbells. Napoleon Bonaparte was so impressed with the invention that he recommended honors for Volta, including making him a count in 1810 (CIRL, Rubin, Scratch, Corrosion Doctors). From this first and crude battery evolved electrochemistry, electromagnetism, and modern applications of electricity (CIRL,

Unless this protocol acquires a mainstream application, it is likely that it will never be put to extensive use. Applications Wireless technologies are becoming incredibly common. Convenience-conscious consumers like the lack of wires, although they dislike short battery lives and unexplainable hardware failures caused by jammed radio frequencies. Bandwidth is a primary consideration where wireless protocols are concerned. The upcoming 802.11n, capable of actual throughput rates of over 200Mb/s, is capable of

Nano particles and nano tubes are on the small scale of a virus, which is why the living organism is crucial for downsizing the materials that are customarily used in portable rechargeable batteries. The new batteries will be more powerful and also prove less taxing on the environment. Manufacturing the virus-assisted batteries will also be more efficient and safer, as no solvents are needed to manipulate them and engineers

Non-Price Barriers to Entry In the OEM business, ongoing contracts are a strong driver of future sales. Once Larson becomes the battery supplier for a company, it can build a strong relationship with that company. The result will be a non-price barrier to entry as smaller firms find it difficult to break the relationships that Larson forms with its customers. Without those customers, there will be less room for growth and
