Li-ion batteries make use of Lithium substance which is lightweight and has high level of electric & chemical standard of potential as a material to retain the battery voltage (~4V) and high energy density; and also an innovate device which developed the problems related to metal Lithium safety by the flowing of Lithium ions between anode and cathode through organic electrolyte. These can play a crucial role in making electronic devices to become smaller and lighter, and high -powered batteries applied in High End type of Mobile electronic devices.
