1. Batteries
The battery is a device that converts chemical energy into electricity. Like most important inventions, this device has many different versions originating from the 19th century, making the history of the battery quite interesting. The battery is a combination of many different elements that have spawned new and inventive ways of creation through the comprehension of its creation, used for almost every aspect of modern life. The battery has made a progressive transformation from a crude invention made of simple elements to one of complexity and vast potential. The battery has helped in the growth of technology, and has become a big innovation toward modern living because of it. .
The invention of the battery can be dated back to 250B.C. in Baghdad, Iraq where it was used in a process to electroplate objects with a thin layer of metal just like how gold and jewelry are plated today. From 1780 to about 1786, Luigi Galvani observed that when pieces of iron and brass are connected to frog's legs, he got them to twitch. This started the interest in what was known as voltaic electricity, after Alessandro Volta. From 1796-1799 he experimented with such elements as Zinc and Silver and invented what was known as the first "dry" battery consisting of a pile of the two elements. Before the turn of the century, he had modified this using a salt solution and it was called the "crown of cups". The successful use of liquid electrodes were later developed by Karl Gilbert Grove in 1839 and Robert Wilhelm Bunsen in 1842. By 1866, the French Engineer Georges Lelanche had made his own patent out of a porous pot with crushed Manganese dioxide with a little Carbon (positive) mixed in with a Zinc rod (negative). In just two years, his version had sold 20,000 battery for telegraph machines. The idea of placing both the negative and porous pot into a Zinc capsule was conjured up by J.A. Thiebaut in 1881. Carl Gassner of Maine is credited for his design of the first commercially successful "dry" battery.

Major corporation, Tesla Motors, has been rumored to be one company developing new Graphene batteries. ... Equally important, we can now drastically cut down the toxic waste generated by disposed batteries, since our batteries last 10 times longer than the current generation of lithium-ion batteries.... Because the key ingredient, titanium dioxide, is both abundant and environmentally safe, the Graphene battery suitably replaces the inferior, modern lithium-ion battery that's used today. Nanyang professor Rachid Yazami, who co-invented the lithium-graphite anodes used in lithium-ion batt...
