Preparation and characterization of graphite anode for lithium ion batteries
(Advanced Batteries, Accumulators and Fuel Cells, 2014-08-24)
The lithium-ion batteries are energy storage systems of high performance and low cost for use in multiple portable devices. These require the use of increasingly smaller and lighter batteries with high energy and power ...
Preparation and characterization of positive electrode of NiMH batteries with cobalt additives
(Elsevier, 2014-02-18)
The present paper shows the preparation and characterization of alkaline batteries cathodes formed by nickel hydroxide with the addition of cobalt. This additive was incorporated by two methods: on the electrode surface, ...
Effect of different additives on the electrochemical behaviour of nickel hydroxide electrodes employed in batteries
(Annual Meeting of the International Society of Electrochemistry, 2014-08-31)
Nickel hydroxide is widely used as the active material in positive electrodes in most nickel-based rechargeable alkaline batteries. The theoretical capacity of nickel hydroxide is 289 mAhg-1. The capacity of these batteries ...

Clave de líquenes creciendo sobre cemento y hormigón en la provincia de Buenos Aires, Argentina
(Grupo Latinoamericano de Liquenólogos, 2014)
Los líquenes crecen sobre una gran variedad de sustratos, entre estos los materiales fabricados por el hombre. Este trabajo se centra en los líquenes que son capaces de crecer sobre cemento. Se colectaron los líquenes ...
Hydrothermal synthesis of cathode materials for rechargeable lithium ion battery
(Annual Meeting of the International Society of Electrochemistry, 2014-08-31)
The Lithium-ion batteries are electrochemical systems based on the use of intercalation compounds supported on porous structures with different characteristics. The Li-ion battery operates by intercalation of Li+ cations ...
Contribución de diferentes aditivos en el comportamiento electroquímico de electrodos de hidróxido de níquel
(Mattear, 2014-05-13)
El hidróxido de níquel es utilizado como material activo en electrodos positivos de las baterías alcalinas recargables de níquel. La capacidad de estas baterías depende de la capacidad específica del electrodo positivo y ...
Effect of cobalt electroless deposition on nickel hydroxide electrodes
(Elsevier, 2014-02-21)
The effects of cobalt additive on the positive electrode surface of nickel alkaline batteries are investigated. Electrode surface modifications by electroless cobalt deposits were made at different immersion times. The ...
Estudio de catalizadores para el cátodo de una celda de combustible de metanol directo
(Investigación Joven, 2014)
Las celdas de combustible de metanol directo, DMFCs, convierten la energía química almacenada en el metanol en energía eléctrica de forma eficiente y con bajo impacto medioambiental. Las DMFCs tienen como ventajas que el ...
