A battery is a device for storing chemical energy and converting that chemical energy into electricity. The electrons are generated by chemical reactions, and there are many different chemical reactions that are used in commercially available batteries. Automobile manufacturers have identified three types of rechargeable battery as suitable for electric car use.
Lead-acid batteries were invented in 1859 and are the oldest form of rechargeable battery still in use. Lithium-ion batteries, which came into commercial use in the early 1990s, have a very high energy density and are less likely than most batteries to lose their charge when not being used -- a property called self discharge.

The project will examine the potential of reusing spent lithium-ion battery packs from GM’s electric car, the Chevrolet Volt, as a means of providing cost-effective energy storage capacity, which will improve the efficiency of electrical systems as they evolve into smart grids.
According to GM, the Volt’s battery will still have significant capacity to store electrical energy, even after its automotive life.
ABB is currently at work on more than 20 projects around the world examining all aspects of the smart grid, from energy storage to network management, metering and communication, distribution automation and home automation systems.
Here's a view of a car you've probably not seen before, though it may be familiar to you if you've ever been in the hospital.
The image above shows the 2012 Mitsubishi i electric vehicle after an X-ray scan, allowing you to see many of the vehicle's key components.
It weighs just over 440 pounds including frame fixings and contains 88 lithium-ion cells in 22 modules. Behind the battery pack in the x-ray image is the electric motor, and this can be seen sitting below two square-shaped objects. The electric motor in this European-specification i provides 133 pounds feet of torque and 63 horsepower, enough for 87 miles per hour and 0-62mph in 13 seconds. Emerging either side of the motor are the driveshafts leading to the rear wheels, and you can clearly see the suspension components too.
A battery is made up of one or more electrochemical cells, each of which consists of two half-cells or electrodes. For example, the familiar alkaline batteries commonly used in flashlights and television remote controls generate electricity through a chemical reaction involving zinc and manganese oxide.
Those types are lead-acid batteries, nickel metal hydride (NiMH) batteries, and lithium-ion (Li-ion) batteries.

They've been used in all types of cars -- including electric cars -- since the 19th century. They have a high energy density -- that is, a great deal of energy can be packed into a relatively small battery -- and don't contain any toxic metals, so they're easy to recycle. Because of their light weight and low maintenance requirements, lithium-ion batteries are widely used in electronic devices such as laptop computers.
21, 2010 – ABB, the leading power and automation technology group, and General Motors have signed a non-exclusive memorandum of understanding to cooperate on a research and development project that will investigate uses for electric vehicle batteries once their useful life in the vehicle is over. The ABB Group of companies operates in around 100 countries and employs about 117,000 people.
X-rays pass cleanly through fabrics, plastics and thin sheets of metal such as the vehicle's roof, allowing you to see the denser objects below.
The big blue rectangle sitting in the center of the vehicle between the chassis rails is the Lithium-ion battery pack. Mitsubishi claims a 93,600 mile battery range and it's expected to hold 80 percent capacity after ten years.
The smaller of these is the charger module, the larger and more simple-looking is the inverter.
The U.S-specification Mitsubishi i has been given a 112 MPGe rating by the EPA, but an official range of only 62 miles. There's less going on at the front of the car, though the large oval is the car's windscreen, and the wiper is visible near the front of the car. One half-cell, called the negative electrode, has an overabundance of the tiny, negatively charged subatomic particles called electrons. Lead-acid batteries are a kind of wet cell battery and usually contain a mild solution of sulfuric acid in an open container. Some experts believe that lithium-ion batteries are about as close as science has yet come to developing a perfect rechargeable battery, and this type of battery is the best candidate for powering the electric cars of the near future. Advertisement By The Engineer - July, 1st 2014IntroductionAn electric battery is defined as a device that makes use of either one or an assembly of electrochemical cells that convert the stored chemical energy within them into electrical energy. It's mounted low in the car beneath the passenger compartment, which not only saves space but makes the center of gravity lower for improved handling over the gasoline version available in some markets. A spaghetti of reinforced cables links these to the motor, and a further two are connected to the battery. The name comes from the combination of lead electrodes and acid used to generate electricity in these batteries.

A variation on lithium-ion batteries, called lithium-ion polymer batteries, may also prove valuable to the future of EVs. Not clearly visible in the image, a connection point each side of the car feeds into the charger - one for regular charging and the other for quick charging. When the two halves are connected by a wire or an electrical cable, electrons will flow from the negative electrode to the positive electrode. Automobile batteries, on the other hand, need to be rechargeable, so they don't require constant replacement. The major advantage of lead-acid batteries is that, after having been used for so many years, they are well understood and cheap to produce. These batteries may eventually cost less to build than lithium-ion batteries; however, at the present time, lithium-ion polymer batteries are prohibitively expensive. An estimate carried out in 2005 concluded that worldwide battery industry roughly generates $48 billion in annual sales with a 6% annual growth. In a rechargeable battery, electrical energy is used to reverse the negative and positive halves of the electrochemical cells, restarting the electron flow. However, they do produce dangerous gases while being used and if the battery is overcharged there's a risk of explosion. The energy of these moving electrons can be harnessed to do work -- running a motor, for instance.
Alessandro Volta described the first electrochemical battery known as voltaic pile in 1800.How Does a Battery Work?
As electrons pass to the positive side, the flow gradually slows down and the voltage of the electricity produced by the battery drops.
Eventually, when there are as many electrons on the positive side as on the negative side, the battery is considered 'dead' and is no longer capable of producing an electric flow.
