The positive attributes of nanomaterials to the field of electrochemical energy storage

The field of energy electrochemical storage is presently living, many years after that of microelectronics, its "nanomania" with, among others, non porous materials, nanotextured/nanostructured electrodes and nanoarchitectured current collectors. Beyond the composition and crystalline structure of electrode materials, what are the benefits that this third component, namely the size, could bring to batteries and supercondensators? Are we talking of a revolution? What are the effects on the energy electrochemical storage? This paper tries to give an answer to these different questions.
