Electrochemical investigations of ion-beam sputter-deposited carbon thin films for Li-ion batteries have recently been drawing attention. This is because of the fact that they have very good adhesion and very high damage threshold, and thus add to the longevity of the batteries. Another recent development has been the evolution of the High-power Laser Coatings Technology. The present paper discusses technically many important aspects - materials and the coating techniques for the development of such coatings, and present important findings for various types of high-power lasers. Finally, it has been suggested to use DIBS Technique for coating the batteries after discussing the magnitude of the improvement in the performance and longevity of the batteries. Also optimization of performance parameters has been presented.
