“…The diffraction peaks of Al and Li 2-x FeS 2 appears at C1-2.5 V in Figure 7a, which indicates that Li 2-x FeS 2 is produced in subsequent cycles rather than FeS 2 . This is in accordance with Ardel's report [29]. There are some absorption peaks between 200 and 300 nm´1 at C1-2.5 V in Figure 7b, which are brought about by small sulfur molecules produced by side reactions during the charging and others in DMF [28].…”

Nanoscale FeS 2 was synthesized via a simple hydrothermal method and was decorated by hydrothermal carbonization (FeS 2 @C). The structural properties of the synthesized materials detected by X-ray diffraction (XRD), together with the morphologies characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) indicated that the hydrothermal carbonization only had an impact on the morphology of pyrite. Additionally, the electrochemical performance of the coated pyrite in Li/FeS 2 batteries was evaluated by galvanostatic discharge-charge tests and electrochemical impedance spectroscopy (EIS). The results showed that the initial capacity of FeS 2 @C was 799.2 mAh¨g´1 (90% of theoretical capacity of FeS 2 ) and that of uncoated FeS 2 was only 574.6 mAh¨g´1. XRD and ultraviolet (UV) visible spectroscopy results at different depths of discharge-charge for FeS 2 were discussed to clarify the electrochemical mechanism, which play an important part in Li/FeS 2 batteries.

“…The disadvantage of these electrolytes is that many problems imposed by liquid electrolytes (solvents) are still present: the potential hazards due to leakage of the highly fl ammable organic solvents and the formation of a Solid Electrolyte Interphase (SEI). [ 123 ] Therefore a second class of polymer electrolytes was developed, the Solid Polymer Electrolytes (SPE) that do not rely on liquid electrolyte solutions. A classic example of such a SPE is a complex of a lithium perchlorate salt with poly(ethylene oxide).…”

“…This combination was previously found to yield high ionic conductivities when impregnated with liquid electrolytes: ionic conductivities up to 2 ⋅ 10 − 3 S ⋅ cm − 1 were reported. [ 123 ] The anode precursor consisted of a slurry, comprising mesocarbon microbeads (MCMB), which was also deposited by consecutive spincoating and evacuation steps. The coating evacuation cycle was repeated until the microchannels were completely fi lled.…”

With the increasing importance of wireless microelectronic devices the need for on-board power supplies is evidently also increasing. Possible candidates for microenergy storage devices are planar all-solid-state Li-ion microbatteries, which are currently under development by several start-up companies. However, to increase the energy density of these microbatteries further and to ensure a high power delivery, three-dimensional (3D) designs are essential. Therefore, several concepts have been proposed for the design of 3D microbatteries and these are reviewed. In addition, an overview is given of the various electrode and electrolyte materials that are suitable for 3D all-solidstate microbatteries. Furthermore, methods are presented to produce fi lms of these materials on a nano-and microscale.www.MaterialsViews.com REVIEW www.advenergymat.de

“…En las últimas décadas se han logrado grandes avances en el desarrollo de materiales tecnoló-gicos con alto valor añadido basados en compuestos con estructura abierta 3D, formados a partir de estructuras laminares 2D (arcillas catiónicas, hidróxidos dobles laminares, sulfuros y óxidos de metales de transición, etc.). Estos materiales pueden albergar moléculas orgá-nicas entre sus láminas, dando lugar a híbridos orgánicos-inorgánicos, que han despertado el interés por la formación de nuevos compuestos sólidos muy interesantes: materiales con propiedades conductoras, magnéticas y ópticas (2)(3)(4)(5), o los más recientemente empleados por la mejora de sus propiedades mecánicas e ignífugas (6).…”

Se aborda la intercalación de un compuesto orgánico, 2-hidroxil etil trimetil amonio (Colina), entre las láminas de bronce azul de molibdeno.El sólido obtenido se caracteriza mediante análisis químico (AQ), difracción de rayos-X (XRD), análisis térmico (DTA y TG) y espectroscopia infrarroja (FT-IR). La utilización de un bronce sódico de molibdeno recién preparado facilita la incorporación de la molécula orgánica, dando lugar a la formación de una única fase laminar. El material híbrido muestra un alto ordenamiento laminar, estable a temperaturas inferiores a los 550 K, que se descompone por combustión del componente orgánico. Los resultado obtenidos indican que el bronce azul de molibdeno puede ser un buen candidato para la obtención de compuestos de intercalación. Palabras clave: Bronce de Molibdeno, Híbrido orgánico-inorgánico, intercalación. Preparation of a new hybrid organic/inorganic material by cholina intercalation into molybdenum bronzesIntercalation of a organic compound, 2-hydroxyl etil trimetil ammonium, in the layered host molybdenum bronzes was achieved. Full characterization of solids was performed using chemical analysis, X-ray diffaction, thermal analysis and IR spectroscopy. Using fresh sodium hydrated layered molybdenum bronce yields a monofasic layered solid. The hybrid organic-inorganic compound exhibs a high lamellar order, which is stable at temperatura below 550 K, then collapsing by combustion of organic component. All features show that blue molybdenum bronzes will be a good host for intercalation. Key words: Molybdenum bronze, hybrid organic-inorganic, intercalation INTRODUCCIÓNLa búsqueda de nuevos materiales compuestos para mejorar propiedades tales como microporosidad, actividad catalítica, propiedades electrónicas, propiedades mecánicas, etc., supone una activa línea de trabajo en la química del estado sólido (1). En las últimas décadas se han logrado grandes avances en el desarrollo de materiales tecnoló-gicos con alto valor añadido basados en compuestos con estructura abierta 3D, formados a partir de estructuras laminares 2D (arcillas catiónicas, hidróxidos dobles laminares, sulfuros y óxidos de metales de transición, etc.). Estos materiales pueden albergar moléculas orgá-nicas entre sus láminas, dando lugar a híbridos orgánicos-inorgánicos, que han despertado el interés por la formación de nuevos compuestos sólidos muy interesantes: materiales con propiedades conductoras, magnéticas y ópticas (2-5), o los más recientemente empleados por la mejora de sus propiedades mecánicas e ignífugas (6).El trióxido de molibdeno es un ejemplo de material con estructura laminar que puede experimentar reacciones de intercalación. La estructura del MoO 3 puede ser descrita como infinitas cadenas de octaedros MoO 6 que comparten vértices y ejes dando lugar a la formación de láminas onduladas, de espesor 6.928 Å, que se colocan paralelas entre sí, pudiéndose ser representadas por la fórmula MoO1/1O2/2O3/3 (que indica que el Mo está octaédricamente coordinado a un átomo de oxígeno no compartido, a ...
