We perform ab initio calculations, within the density functional theory framework, of different lithium titanate compounds. In particular, Li 4 Ti 5 O12 (whose lithiated form is Li 7 Ti 5 O12) can be used as an anode in Li-ion batteries. Because of t

By means of Density Functional Theory (DFT) calculations we investigated the optimal pore size for reduced graphite oxide (GOH) to favor hydrogen storage and to prevent oxygen interference. The interlayer distance of GOH is found to increase with oxy
