Preparation and characterization of positive electrode of NieMH batteries with cobalt additives
The present paper shows the characterization and electrochemical behavior of alkaline batteries cathodes formed by nickel hydroxide with the addition of cobalt. This additive was incorporated by two methods: on the electrode ...
Modeling of a Vanadium Redox Flow Battery for power system dynamic studies
Vanadium Redox Flow Battery (VRB) is an electrochemical energy storage system based on a reversible chemical reaction within a sealed electrolyte. Several models have been developed which now offer a good understanding of ...
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 ...
Phenomenological Model-Based Analysis of Lithium Batteries. Discharge, Charge, Relaxation Times Studies. Cycles Analysis
The discharge and charge processes operation of lithium ion batteries is addressed. A simple phenomenological model is developed in order to predict all variables values. A set of algebraic and differential equations is ...
Model based analysis of lithium batteries considering particle-size distribution
(John Wiley & Sons Inc, 2018-03)
Performance of lithium ion batteries whose electrodes are composed of particles of different sizes is studied. Simplified model developed in (Henquín and Aguirre, AIChE J. 2015; 61:90–102) is extended and the simulations ...
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 ...
The kinetics of oxygen electroreduction: a long way from iron rust to lithium-air batteries
(Wiley VCH Verlag, 2014-03)
In this communication, we review the details of the oxygen electroreduction reaction on rust layers, passive iron and well defined iron oxides as cathodes for the reaction. In particular, we highlight the important ...
