What is battery?
A battery is an electrochemical device
in which electrical energy is converted and stored in chemical form for
storage. The chemical energy can then be easily reconverted into electrical
energy (Amrita University, 2015).

History
G.N. Lewis was the first person to start working on lithium batteries(Delaney, 2010). M.S Whittingham from the university of Birmingham University, Exxon was the first person to develop and come up with the concept of the lithium ion battery (Delaney, 2010). He used a titanium sulfide and lithium to power a battery he conceived in the 1970’s (Delaney, 2010). Lithium was also known to be the lightest metal, it has the greatest electrochemical potential and provides the largest energy density for weight (Delaney, 2010). The Lithium batteries failed to become rechargeable batteries because of some safety issues that germinated mainly while recharging the batteries (Buchmann, 2015). This is the reason why the experimentation was done with the help of the intercalation technique using lithium’s electrochemical properties and graphite in the year of 1980 by Dr. Rachid Yazami who worked with French National Center for Scientific Research and Grenoble Institute of Technology and published a work in a year which showed that lithium intercalation in graphite was as expected a reversible reaction and could also be used in the making of rechargeable lithium batteries (Buchmann, 2015). Furthermore, the use of lithium metal was also confined and some other form of lithium containing lithium ion was used (Buchmann, 2015). This kept going on until Sony released the first lithium ion battery on commercial scale (Buchmann, 2015).
