structure2Task #2 is dedicated  to the screening of different multi-cation oxides aiming at the choice of two major chemistries that can provide significant improvement compared to existing monoxides: higher capacitance, higher density, better long term cycling ability. Some additional time will be devoted to the optimization of attractive chemistries, in order to investigate doping alternatives to first or second selected chemistries.

Task #3 is dedicated to electrode architecture for oxide-based supercapacitors and to the formulation of the electrode materials which will be benchmarked in task #4. As electrode materials, most of the pseudocapacitive metal oxides show limited electronic conductivity, either intrinsically or as dispersed nano-powders. On the other hand, the architecture of the electrode also impacts on the ion diffusion and transport through the material. Task #3 will address both limitations by developing specific electrode formulations for the oxides prepared in task #2.

Task #4 is dedicated to the design of prototype cells. In 2014, LRCS acquired pre-transfer equipments for the fabrication of “industrial” batteries and supercapacitors including a coater, a calendering machine and a cell winder together with a tab welding machine and all the facilities to prepare large quantities of slurries. All these equipments can be easily used for Li-ion or supercapacitor cells.
