Here we present an ultraviolet responsive inorganic-organic hybrid solar cell based on titania/poly(3-hexylthiophene) (TiO(2)/P3HT) heterojuction. In this solar cell, TiO(2) is an ultraviolet light absorber and electronic conductor, P3HT is a hole conductor, the light-to-electrical conversion is realized by the cooperation for these two components. Doping ionic salt in P3HT polymer can improve ...

We report the results of spatial resolution and conversion efficiency measurements on new fluorochlorozirconate and lithium-borate glass-ceramics that are being researched for x-ray and thermal neutron imaging applications. The sensitivity of the fluorochlorozirconate glass-ceramics containing BaCl2:Eu nano-crystallites is up to 80 % of that found in BaFBr(1000ppm Eu), which is the material use...

A superfine Li0.33La0.557TiO₃ (LLTO, 69.4 nm) was successfully synthesized by a facile solvent-thermal method to enhance the electrochemical properties of the lithium-ion battery separator. Co-axial nanofiber of cellulose and Poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) was prepared by a co-axial electrospinning technique, in which the shell material was PVDF-HFP and the core was...

Among the alternative host materials for solid polymer electrolytes (SPEs), polycarbonates have recently shown promising functionality in all-solid-state lithium batteries from ambient to elevated temperatures. While the computational and experimental investigations of ion conduction in conventional polyethers have been extensive, the ion transport in polycarbonates has been much less studied. ...

The functionality and reliability of portable microelectronics systems is often limited by the ability of the power supply to provide a continuous source of energy. In modern portable applications, lithium ion, and lithium polymer batteries have become the choice energy system. The selection of these batteries is based on their high volumetric and gravimetric energy densities and their ability ...

We evaluate miniature batteries as potential power sources for advanced wildlife telemetry tags. These tags are often based on integrated UHF transceivers that are designed for wireless sensor networks and that consume 18-85mA while receiving or transmitting. This current drain is challenging for many types of miniature batteries. We evaluate batteries both on actual tags and in a specialized s...

The electrode electrolyte interface is essential to our understanding of batteries and how they operate. In this article we examine the between three polymer electrolytes lithium metal using photoelectron spectroscopy.

Novel ionic liquid polymer electrolytes based on polymer poly(vinylidene fluoride-co-hexafluoropropylene) (PVdF-HFP), lithium bis(tri-fluoromethanesulfonyl)imide (LiTFSI) with different 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (EMITFSI) weight ratios have been synthesized and applied to quasi-solid state Li–air batteries. The morphology, electrochemical properties of prepa...

The state of the art of conversion reactions of metal hydrides (MH) with lithium is presented and discussed in this review with regard to the use of these hydrides as anode materials for lithium-ion batteries. A focus on the gravimetric and volumetric storage capacities for different examples from binary, ternary and complex hydrides is presented, with a comparison between thermodynamic predict...

Using NPT and NVT molecular dynamics simulation techniques, we have simulated an atomistic model of solvated Nafion in the lithium salt form, with the following three main objectives: (i) to obtain details on the local environment of the lithium cations and to assess the solvent effect on their binding, (ii) to investigate the translational and rotational motion of solvent molecules (water and ...
