About the book
This book intends to shed light on some of the most advanced or emerging topics in the field of Li-ion batteries. In this book we will discuss among other topics, Atomic-Layer-Deposition which is a powerful technique allowing accurate control of coatings chemistry, thicknesses, and conformality down to the atomic scale. As such, it attracts a lot of academic and industrial attention for the development of the next generations of advanced Li-ion batteries. Specifically, it could help, among others, in the fabrication of conformal electroactive coatings for micro batteries. A second chapter will be dedicated to a review of micro batteries where microfabrication and integration into microchips challenges need to be addressed. Photo-rechargeable Li-ion batteries emerge recently with the design of bifunctional electrodes combining solar sensing and Li-ion electrochemical activity. The coupling between intermittent solar energy sources and batteries indeed requires specific instrumentation detrimental to the final gravimetric/volumetric density of mobile microsystems. The current performances of such pioneered photo-rechargeable Li-ion batteries are still weak but their future integration into microchips could be very promising. Electrochemical techniques and specifically electrodeposition have already been shown as being powerful in the fabrication of several parts of LIB. A review of some of those results including the electrochemical deposition of active cathodic/anodic materials and the fabrication of 2D/3D current collectors will be given, with a special attention toward innovations in copper current collectors. Finally, an interest towards the most recent forefront R&D outputs in the field of electrolytes (liquid, gel and/or solid) for LIB will be provided to the readers.
