Scientists increasingly witness the applications of MoS2 and MoO2 in the field of energy conversion and energy storage. On the one hand, MoS2 and MoO2 have been widely utilized as promising catalysts for electrocatalytic or photocatalytic hydrogen evolution in aqueous solution. On the other hand, MoS2 and MoO2 have also been verified as efficient electrode material for lithium ion batteries. In...

In this paper we used a previously reported model for examining the adsorption of nonelectrolytes in solution by solid adsorbents to study the adsorption of lithium(I) cations by acid and sodium amberlites, which is an ion-exchange process. Based on the results, both are equilibrium processes and obey a kinetic law with a unity partial order in the Li+ concentration. The kinetic results were us...

In this study, both experimental ionic conductivity measurements and the first-principles simulations are employed to investigate the Li(+) ionic diffusion properties in lithium-based imides (Li(2)NH, Li(2)Mg(NH)(2) and Li(2)Ca(NH)(2)) and lithium amide (LiNH(2)). The experimental results show that Li(+) ions present superionic conductivity in Li(2)NH (2.54 × 10(-4) S cm(-1)) and moderate ionic...

A two-dimensional layered Ti3C2/carbon nanotubes (CNTs) hybrid thin film was prepared. Owing to the excellent conductivity of the CNTs, this unique layered structure provides a rapid charge transfer path during the electrochemical reaction, as a lithium ion battery anode, which exhibits higher capacitance and better cycling stability (a reversible capacity of 428.1 mA h g(-1) at 0.5 C after 300...

A novel composite of Fe(2)O(3) and single-walled carbon nanohorns (SWCNHs) was firstly developed via a simple hydrothermal method. As an anode material for lithium ion batteries, a Fe(2)O(3)/SWCNHs composite shows excellent rate performance and cycle stability, even at a high current density of 1000 mA g(-1).

A configuration of three-dimensional Ni-Si nanocable array anodes is proposed to overcome the severe volume change problem of Si during the charging-discharging process. In the fabrication process, a simple and low cost electrodeposition is employed to deposit Si instead of the common expansive vapor phase deposition methods. The optimum composite nanocable array electrode achieves a high speci...

A supramolecular binding occurred between lithium ion encapsulated [60]fullerene (Li(+)@C(60)) and sulfonated tetraphenylporphyrins ([MTPPS](4-) M = H(2) and Zn) in a benzonitrile solution. Photoexcitation of Li(+)@C(60)/[MTPPS](4-) results in formation of a long-lived charge-separated state by photoinduced electron transfer.

Graphene is composed of a single atomic layer of carbon which has excellent mechanical, electrical and optical properties. It has the potential to be widely used in the fields of physics, chemistry, information, energy and device manufacturing. In this paper, we briefly review the concept, structure, properties, preparation methods of graphene and its application in lithium ion batteries. A con...

The title compound, [Li(2)(C(18)H(22)BO)(2)(C(6)H(7)N)(2)], is a lithium dimesitylboroxide dimer in which the lithium cation is also coordinated by one mol-ecule of 2-methyl-pyridine. At the core of the structure is an Li(2)O(2) four-membered ring. The structure is centrosymmetric with an inversion centre midway between two Li atoms. Inter-molecular C-H⋯π inter-actions and π-π inter-actions bet...
