During the extraction of lithium from high Mg-containing salt lake brines by tributyl phosphate (TBP) in the presence of Fe(III), H+ is used to stabilize Fe(III). However, the distribution ratio of H+ (D-H) is 4-6 times higher than that of Li+ (D-Li), which affects the extraction of Li+ significantly. In this study, the competition mechanism betwee...

The combination of ionic liquids (ILs) and metal organic frameworks (MOF) as a new type of hybrid ionic conductor has raised extensive concern. Novel solid electrolytes with high ionic conductivities and good cycle performance have been successfully synthesized by loading ILs into nanoarchitectures of MOF materials. In this work, two highly conduct...

Despite their high theoretical capacity density (1675 mAh g(-1)), the application of Li S batteries has been seriously hindered by the shuttle effect of polysulfides. Here, inspired by the working principle of natural spider webs, we synthesized a spider-web-like nanocomposite in which many hollow mesoporous silica (mSiO(2)) nanospheres/Co nanopart...
Porous architectures are important in determining the performance of lithium-sulfur batteries (LSBs). Among them, multiscale porous architecutures are highly desired to tackle the limitations of single-sized porous architectures, and to combine the advantages of different pore scales. Although a few carbonaceous materials with multiscale porosity a...
Developing higher capacity electrode materials is a key challenge in battery advancement. Metal oxides undergoing conversion and/or alloying reactions offer high capacities, but suffer from volumetric changes and poor conductivities. However, combining several of these oxides can induce a synergistic effect, enhancing electrode characteristics. Usi...
The benefits of nanosize active particles in Li-ion batteries are currently ambiguous. They are acclaimed for enhancing the cyclability of certain electrode materials and for improving rate performance. However, at the same time, nanoparticles are criticized for causing side reactions as well as for their low packing density and, therefore, poor vo...

Using density functional theory based computations; the role of vacancy and defects in hydrogen terminated silicon nano particles (NP) in the lithium intercalation process is investigated. The study shows that Li cannot bind to the NPs without vacancy or defects. The presence of a single dangling bond or defects such as O or OH radical substituting...
