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

Introduction Batteries are used every day in a variety of different devices. They allow us to charge an object and store power for later use. While batteries are a big part of daily human life they also present a challenge to society in terms of environmental sustainability. Not only do these batteries have harmful chemicals which can end up in landfills‚ but they also encourage over consumption because the more products you buy‚ the more batteries you need‚ and the more batteries must be produced

Investigatory Project I. Problems and Setting A. Introduction Batteries‚ years ago‚ have taken the world by a storm and have since than became a necessity in one’s household. Sadly‚ even though they are tremendously useful‚ batteries have drawbacks‚ such as semi- affordable costs‚ limited shelf life and pollution. I had an idea on how to make an alternative to this that would not only work like the real thing but would also be healthy to our environment and light in my pockets

Lemon Battery creating a battery from a lemon is a common project in many science text books. Successfully creating one of these devices is not easy. Batteries consist of two different metals suspended in an acidic solution. Copper and Zinc work well as the metals and the citric acid content of a lemon will provide the acidic solution. Batteries like this will not be able to run a motor or energize most light bulbs. It is possible to produce a dim glow from an LED. The picture at the top

Potato Batteries: Veggie power! Data and Analysis Background The battery was invented around 1800 by Alessandro Volta in Italy. It has become an indispensable part of modern life. Why are batteries so useful? Because they convert chemical energy into electrical energy. You can use this electrical energy to light a flashlight‚ to start a car‚ or to listen to your favorite music. We made a simple battery out of a potato by placing in it a zinc strip and a copper strip. At the zinc strip‚ the

portable electronic devices is increasing‚ the demands for longer battery life are also increasing. These batteries need to be recharged or replaced periodically. It is a hassle to charge or change the battery after a while‚ especially when there is no power outlet around. Therefore‚ our team is inspired to design a wireless battery charger. This wireless battery charger is expected to eliminate all the hassles with today’s battery technology. Wireless power is the transmission of electrical energy

A battery‚ which is actually an electric cell‚ is a device that produces electricity from a chemical reaction. In a one cell battery‚ you would find a negative electrode; an electrolyte‚ which conducts ions; a separator‚ also an ion conductor; and a positive electrode. Batteries are made of magnesium dioxide‚ graphite‚ electrolytes‚ zinc oxide and a paper soaked in an electrolyte solution. All of this is sealed in a insulated tube for safety. http://answers.ask.com/consumer_electronics/other/what_are_batteries_made_of
