In the majority of the classes of organised electrolytes, the main challenge is to find an innovative strategy of defect management at the mesoscopic scale. For an ultimate exploitation of the functional properties of self-organised and -assembled nanostructured soft materials, their structure and morphology have to be precisely controlled and tuneable in a large range of length and time scales. Different strategies aim to go beyond the state-of-the-art level of achievable ionic transport through notably a better understanding of the mesoscopic structure/transport interplay. Several ways permit to modify/tune the polar/nonpolar segregation of the ionic liquids up to long-range scales. Then the choice of ions, their confinement and/or the modification of their organisation at the molecular scale lead to more efficient self-assembly and ionic transport. Some of these electrolytes present a directed ion transport. In this context of directional confined ionic transport, hierarchical self-assembly of ionic liquids are originally combined: hybrid materials by anchoring, complexed or/and self-organised ionic liquids. To properly address this crucial role, concomitant works in the direct space to give access to the carrier dynamic through impedance spectroscopy is highly relevant. In addition, multimodal physical characterization techniques are coupled notably with the use of the large scale facilities and especially Small Angle Neutron/X-ray scatterings.
