how do bateries work?adn why do they die after a while??

Answer 1

They convert chemical energy to electrical energy.
They die when all the chemical energy is converted into electrical energy.

Answer 2

As stated above, chemical reaction. IF, you know someone with a Volt Meter; Take a Real Lemon, put a Copper wire in one end and a Steel nail in the other. Wait a few minutes and With the Volt meter on lowest setting Measure the Voltage on the Nail and Wire. You have just made a Battery. The Acid in the Lemon/Battery reacts to produce a "Difference of Potential" this what ALL Batteries do, using Different Chemicals and Metals.
Below me; mapleguy seems to have a good short explain for you, and, a diagram.

Answer 3

Battery:

Electricity.
Two or more connected cells that produce a direct current by converting chemical energy to electrical energy.
A single cell, such as a dry cell, that produces an electric current.

In science and technology, a battery is a device that stores energy and makes it available in an electrical form. Although such storage in an electrostatic form is practical in some specialized uses (in a capacitor), batteries usually consist of electrochemical devices such as one or more galvanic cells or more recently fuel cells, and may in the future use other technologies. The battery industry is worth 2.8 billion dollars annually.
In a technical sense, the distinction may be made between

an electrical battery, a device for creating or storing electrical energy composed of several similar (usually identical) cells that are connected together, versus
an electrical cell, a single such unit, possibly one cell in a (strict-terminology) battery of multiple cells or possibly the entire device.
That distinction, however, is considered pedantic in most contexts (other than the expression dry cell), and in current English usage it is more common to call a single cell used on its own a battery than a cell.
An example is a double A (AA) battery. Even though most people call it a battery, in reality it is a cell (as are the other lettered designations although one often hears the more-correct "D cell" or "C cell"). A car battery is a true "battery" because it uses multiple cells inside of it that are connected together in series, thus forming a battery. Similarly, a 9-volt battery is a true battery as it must contain more than one cell. Multiple batteries or cells may also be refered to as a battery pack as a set of multi-cell 12v batteries in an electric vehicle.

Over time the materials used to make the battery deteriorate. As they do the battery losses power. If it is rechargeable the materials can be re-energized for a period of time. Still as the materials deteriorate the battery losses life force and eventually can no longer hold a charge.

Answer 4

Batteries are a source of chemical potential energy. You provide a path for electrons to travel from a high potential state to a low potential state (kind of like falling downhill). Batteries are used up when the potential energy is depleted - which can be accomplished by maintaining the path for flow, or due to the battery developing an internal path for the electrons to flow.

Answer 5

 ________

|   xxxxxxxxxxx (+)
|________|
(-)

The cathod, (-) is made of one type of metal
The Anode (+) is anoher type of metal. They are at difdferent electrical potential.
The batter is filled with an acid compound to speed up the action.
Electrons travel from the anode to the cathode inside the battery, and this causes the anode to slowly corrode.
When it is all corroded, and almost gone, the batter will be dead. The metal from the anode will have coated, (plated), the inside of the cathode.

This same type process is used to do chrome plating.
You can learn more by looking it up on the web.

Answer 6

electro plating one metal passes through a solution of another metal that movement creates electrons, which creates power. When all the metal ions have passed throuh the solution the battery dies.

Answer 7

Batteries are charged with electrical energy and when this energy wears out the battery dies. Thank you for your question.

Answer 8

look into nano batteries. they are pretty much the holy grail of batteries. they never die. not apple nano ipod. nano batteries will change the world soon. toshiba has one in their cellphones and 1 charge will last 3 months before u have to recharge it again

Answer 9

Batteries Work, because, they have been, electrically charged.
When they 'Go Down',it is because, the electricity they were 'Charged With', is DEPLETED. They, require Re-Charging, then.

Answer 10

As stated above, no need to repeat it ;o)
We use rechargables so we dont have to keep buying them too often when they run down.
