Electrical cars have been around since the 1800s.The first practical electric car was designed by Thomas Parker in London. The vehicles popularity continued into the 20th century, until the technology of combustible engines advanced and the mass production of gas vehicles. In 2008 the electric car appeared once again because the advances in the battery and power technology, upward prices of oil and emissions. The electrical car originally used a lead acid based battery, today however the lithium ion rechargeable battery is used. The battery of the electric car stores chemical energy and converts the energy to electricity. The chemistry of the electric car is found mainly in the battery. In the battery there is a chemical reaction in cells which then produces a voltage. These batteries usually have 200 to 400 small cells. The cells are combined to create a powerful battery. The risk is that if one cell overcharge it causes a thermal reaction. The development electronic controls for this risk are in process but are expensive. Khalil Amine and Zonghai Chen of the Argonne National Laboratory discovered a molecule base of boron and fluorine added to each cell controls the charging of the battery cells. The molecule is said to be less costly and more reliable than the electric control. (MANDEL, 2009) In the 1800s the lead acid based battery was invented and used in electrical cars. The technologies of the lead-acid battery…
