Electrode surface modifications improve cathode hydrogen production and anode capacity in Ni-MH batteries
(Elsevier B.V., 2006-02-01)
This paper reports results from electrochemical evaluations of electrodes used as cathodes for a hydrogen evolution reaction and anodes in Ni-MH batteries that had been surface-modified by micro-encapsulation, co-deposition ...

Electrochemical characterization of nickel hydroxide nanomaterials as electrodes for Ni-MH batteries
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 ...
Effect of carbon nanotubes purification in the performance of a negative electrode of a Ni/MH battery
(Pergamon-Elsevier Science Ltd., 2014-05-27)
Multiwall carbon nanotubes (MWCNT) with a diameter of 30e50 nm was added to the negative electrode of a NieMH battery in order to study the effect of its purification treatment on the electrochemical performance. Three ...
Spent NiMH batteries-The role of selective precipitation in the recovery of valuable metals
(ELSEVIER SCIENCE BV, 2009)
The production of electronic equipment, such as computers and cell phones, and, consequently, batteries, has increased dramatically. One of the types of batteries whose production and consumption has increased in recent ...

A surface modification for hydrogen storage intermetallic particles by sol-gel method
A new process for the surface modification of hydrogen storage intermetallic particles used as anode material in secondary batteries is proposed in this article. The copper oxide particles coverage obtained by the sol-gel ...
Electrochemical characterization of MWCNT/Ni(OH)2 composites as cathode materials
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 ...
