Preparation and characterization of positive electrode of NiMH batteries with cobalt additives
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, ...
Electrochemical characterization of nickel hydroxide nanomaterials as electrodes for NiMH 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 cobalt electroless deposition on nickel hydroxide electrodes
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
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 performance comparison of MWCNTs Ni (OH)2 composite materials by two preparation routes
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 ...
