The advancement of both batteries and capacitors, two types of EES devices, requires tailored, multifunctional materials whose structure and properties at nanoscale dimensions are thoroughly understood. To underscore this point, the study of electrochemistry at the nanoscale has already broadened the range of materials that can be used in Li-ion secondary batteries. In fact, materials that were previously excluded from consideration under the classical inserlion/de-insertion mechanism are now being reevaluated because, as nanoscale materials, they possess beneficial electrochemical properties (4).
