Abstract

Lithium ion batteries (LIB) are extensively used in most of the day to day portable electronic gadgets,(notepads, iPad, laptops, cell phones) medical industry (pacemakers, defibrillators) electric vehicles and even in aerospace applications. LIB is a secondary battery which works as an electrochemical cell where lithium ions shuttles between the anode and cathode during charge- discharge processes causing the conversion of chemical energy into electrical energy. The first commercial LIB was launched by Sony in 1991 with carbon as anode and LiCoO2 as the cathode. Even though carbon gives the theoretical capacity of 372 mAh /g, the long term cycling of carbon anodes can pose safety issues due to the Lithium dendrite formation and short circuiting of the battery.
