Synthetic control of physicochemical properties of metal oxides is essential to realize the goal of fast ion transport and electron transfer in solid ionic matrices.  Reducing the path length for ion transport both through crystallite size reduction and controlled introduction of ion vacancies can provide significant improvements.  However, conventional nanostructuring techniques employing constraining media can lead to surface coatings manifesting as resistive interfaces, which are often detrimental in energy storage applications.  Of particular benefit are composite materials incorporating both ion and electron conducting materials.  However, intimate connection between the moieties to achieve full utilization is achieved synthetically rather than by mixing of dissimilar materials.  Low temperature, scalable, direct synthetic approaches to achieve well defined stoichiometry, size, and defect distributions in energy storage materials and their composites will be described in this presentation, with an emphasis on materials employing earth-abundant transition metal centers (i.e. iron, manganese).  The beneficial impact on the resultant electrochemistry will be highlighted.
