12 / 88 preparing nano-size or nano-porous particles, and by covering them with a thin electronically conducting layer (generally carbon). however, serious problems still remain: their theoretical specific capacity is still only approx. 170 ah/kg, and the specific gravity is lower compared to that of state-of-the-art licoo2 electrodes. thus, research is needed into basic materi- als design, as well as into their adaption to large-scale applications in vehicles and domestic electrical
