How a Battery is Made

Batteries are made of five basic components:

***A resilient plastic container.
***Positive and negative internal plates made of lead.
***Plate separators made of porous synthetic material.
***Electrolyte, a dilute solution of sulfuric acid and water, better known as battery acid.
***Lead terminals, the connection point between the battery and whatever it powers.


The manufacturing process begins with the production of a plastic container and cover. Most automotive battery containers and their covers are made of polypropylene. For a typical 12-volt car battery, the case is divided into six sections, or cells, shaped somewhat like one row in an ice-cube tray. The cover is dropped on and sealed when the battery is finished.
The process continues with the manufacture of grids or plates from lead or an alloy of lead and other metals. A battery must have positive and negative plates to conduct a charge.

Next, a paste mixture of lead oxide -- which is powdered lead and other materials -- sulfuric acid and water is applied to the grids. Expander material made of powdered sulfates is added to the paste to produce negative plates.

Inside the battery, the pasted positive and negative plates must be separated to prevent short circuits. Separators are thin sheets of porous, insulating material used as spacers between the positive and negative plates. Fine pores in the separators allow electrical current to flow between the plates while preventing short circuits.
In the next step, a positive plate is paired with a negative plate and a separator. This unit is called an element, and there is one element per battery cell, or compartment in the container. Elements are dropped into the cells in the battery case. The cells are connected with a metal that conducts electricity. The lead terminals, or posts, are thenwelded on.

The battery is then filled with electrolyte - or battery acid -- a mixture of sulfuric acid and water, and the cover is attached. The battery is checked for leaks.
The final step is charging, or finishing. During this step, the battery terminals are connected to a source of electricity and the battery is charged for many hours. When the battery is fully charged, it moves to another line where the case is cleaned, if necessary, and the labels are attached.

HI,
Researchers at MIT have developed a new type of lithium battery that could become a cheaper alternative to the batteries that now power hybrid electric cars.

Until now, lithium batteries have not had the rapid charging capability or safety level needed for use in cars. Hybrid cars now run on nickel metal hydride batteries, which power an electric motor and can rapidly recharge while the car is decelerating or standing still.

But lithium nickel manganese oxide, described in a paper to be published in Science on Feb. 17, could revolutionize the hybrid car industry -- a sector that has "enormous growth potential," says Gerbrand Ceder, MIT professor of materials science and engineering, who led the project.

"The writing is on the wall. It's clearly happening," said Ceder, who said that a couple of companies are already interested in licensing the new lithium battery technology.

The new material is more stable (and thus safer) than lithium cobalt oxide batteries, which are used to power small electronic devices like cell phones, laptop computers, rechargeable personal digital assistants (PDAs) and such medical devices as pacemakers.

The small safety risk posed by lithium cobalt oxide is manageable in small devices but makes the material not viable for the larger batteries needed to run hybrid cars, Ceder said. Cobalt is also fairly expensive, he said.

The MIT team's new lithium battery contains manganese and nickel, which are cheaper than cobalt.

Scientists already knew that lithium nickel manganese oxide could store a lot of energy, but the material took too long to charge to be commercially useful. The MIT researchers set out to modify the material's structure to make it capable of charging and discharging more quickly.

Lithium nickel manganese oxide consists of layers of metal (nickel and manganese) separated from lithium layers by oxygen. The major problem with the compound was that the crystalline structure was too "disordered," meaning that the nickel and lithium were drawn to each other, interfering with the flow of lithium ions and slowing down the charging rate.

Lithium ions carry the battery's charge, so to maximize the speed at which the battery can charge and discharge, the researchers designed and synthesized a material with a very ordered crystalline structure, allowing lithium ions to freely flow between the metal layers.

Answer 4

If you beat someone with your fist it's just assault.
If you use a big stick, its Battery.

no but seriously, anodes and cathodes.....errr...
one material has extra electrons,
and one material has a lack of electrons.
electromagnetic "pressure" builds between them
when joined by a conductive material, current is passed
current = number of electrons passing per second.
without connection to drain from one side to the other,
it will just sit storing power.
when the extra electrons are passed, or the other material
can no longer absorb them, the power is equal.
and the battery is depleted.
