Two anode materials for Li ion batteries with different reaction mechanisms : silicon nanowires and ruthenium nitride thin film

Research carried out in our laboratory is devoted to new materials of electrodes for lithium ion batteries. This presentation focuses on anodic materials, especially on two examples, silicon and ruthenium nitride. In both cases, electrochemical properties and structural evolutions are correlated in order to optimize performances in terms of specific capacity, cyclability and rate capability.
