Characterization of anodes for lithium ion batteries
Humana, Rita; Ortiz, Mariela; Thomas, Jorge; Real, Silvia; Sedlarikova, Marie; Vondrak, Jiri; Visintin, Arnaldo (Springer, 2015-08-14)The lithium-ion batteries are energy storage systems of high performance and low cost. They are employed in multiple portable devices, and these require the use of increasingly smaller and lighter batteries with high energy ... -
Effect of cobalt electroless deposition on nickel hydroxide electrodes
Ortiz, Mariela; Castro, Élida Beatriz; Real, Silvia (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 ... -
Electrochemical characterization of MWCNT Ni(OH)2 composites as cathode materials
Ortiz, Mariela; Real, Silvia; Castro, Élida Beatriz (Springer, 2015-09-04)The hydrothermal method was used to synthesize multi-walled carbon nanotube/nickel hydroxide composites (MWCNT/Ni(OH)2). The structure and morphology of the prepared materials were characterized by X-ray diffraction and ... -
Electrochemical characterization of nickel hydroxide nanomaterials as electrodes for NiMH batteries
Real, Silvia; Ortiz, Mariela; Castro, Élida Beatriz (Springer, 2016-08-23)β-Nickel hydroxide was successfully synthesized by a hydrothermal method. Nano-nickel hydroxide material was characterized by X-ray diffraction, infrared absorption spectroscopy, and transmission electron microscopy. They ... -
Electrochemical performance comparison of MWCNTs Ni (OH)2 composite materials by two preparation routes
Ortiz, Mariela; Castro, Élida Beatriz; Real, Silvia (Springer, 2017)Carbon materials are used to improve the nickel hydroxide electrode capacity in rechargeable alkaline batteries. Herein, we present the preparation of multiwall carbon nanotubes/nickel hydroxide composites (MWCNTs/Ni ... -
Preparation and characterization of graphite anodes for lithium ion batteries
Humana, Rita; Ortiz, Mariela; Thomas, Jorge; Real, Silvia; Sedlarikova, Marie; Vondrak, Jiri; Visintin, Arnaldo (The Electrochemical Society, 2014)The lithium-ion batteries are energy storage systems of high performance and low cost.

Preparation and characterization of positive electrode of NiMH batteries with cobalt additives
Ortiz, Mariela; Real, Silvia; Castro, Élida Beatriz (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, ...
