Effects of pretreatment of LM-Ni3.9Co0.6Mn0.3Al0.2 alloy powders in a KOH/NaBH4 solution on the electrode characteristics and inner pressure of nickel-metal-hydride secondary batteries

Effects of Co3O4 as additive on the performance of metal hydride electrode and Ni–MH battery

“…The temperature of NieMH battery increases when charged or discharged and the heat generate from over potential and side-reaction [32,33]. The inner pressure is determined by the reaction speed of gas consumption [4,12,34,35]. A detailed analysis of the cell impedance shows metal hydride electrode is the main contributor and the oxidation, corrosion and pulverization of electrode alloys will increase internal resistance [36,37].…”

Kinetic Investigation of Quaternary Ni Fe P C Composite Coating as a New Catalyst for Hydrogen Evolution Reaction

“…Hydrogen is the cleanest and ideal fuel and it is considered as an ideal energy carrier that can be an alternative to fossil fuels [1]. Hydrogen evolution reaction (HER) is one of the most intensively studied reactions in electrochemistry because it occurs through a limited number of reaction steps with only one reaction intermediate involved [2]. One major aspect of the research undertaken is to improve catalytic electrode materials in terms of their activity, efficiency and mechanical and corrosion stability [3].…”
