Molecular precursor mediated selective synthesis of phase pure cubic InSe and hexagonal InSe nanostructures: new anode materials for Li-ion batteries.

Indium selenides (InSe and InSe) have earned a special place among the 2D layered metal chalcogenides owing to their nontoxic nature and favourable carrier mobility. Additionally, they are also being projected as next generation battery anodes with high theoretical lithium-ion storage capacities. While the development of indium selenide-based batteries is still in its embryonic stage, a simple and easily scalable synthetic pathway to access these materials is highly desirable for energy storage applications.

Improved Li storage performance of SnO nanodisc on SnOquantum dots embedded carbon matrix.

Li-ion batteries with conversion type anode are attractive choice, for electric vehicles and portable electronic devices, because of their high theoretical capacity and cycle stability. On the contrary, enormous volume change during lithiation/delithiation and irreversible conversion reaction limits use of such anodes. To overcome these challenges, incorporating nano-sized SnOon flexible carbonaceous matrix is an efficient approach.

Di--butyltin(IV) 2-pyridyl and 4,6-dimethyl-2-pyrimidyl thiolates: versatile single source precursors for the preparation of SnS nanoplatelets as anode material for lithium ion batteries.

New air and moisture stable di--butyltin complexes derived from 2-mercaptopyridine (HSpy), [BuSn(Spy)], [BuSn(Cl)(Spy)] and 4,6-dimethyl-2-mercaptopyrimidine (HSpymMe) [BuSn(Cl)(SpymMe)], have been prepared and utilized as single-source molecular precursors for the preparation of orthorhombic SnS nanoplatelets by a hot injection method and thin films by aerosol assisted chemical vapour deposition (AACVD). The complexes were characterized by NMR (H, C, Sn) and elemental analysis and their structures were unambiguously established by the single crystal X-ray diffraction technique. Thermolysis of these complexes in oleylamine (OAm) produced SnS nanoplatelets.
