Chemical Composition Of Ni-MH Battery

Dec. 20, 2018

Ni-MH Battery is synthesized by hydrogen ion and metal nickel. The electricity reserve is 30% more than that of Ni-Cd Battery. It is lighter than nickel-cadmium battery, has longer service life and no pollution to the environment. The disadvantage of Ni-MH Battery is that they are much more expensive than nickel-cadmium batteries, and their performance is worse than that of lithium batteries.

Ni-MH Battery Pack Supplier tell you used in the manufacture of nickel-hydrogen batteries, they are mainly divided into two categories. The most common is AB5, A is a mixture of rare earth elements (or) plus titanium (Ti); B is nickel (Ni), cobalt (Co), manganese (Mn), (or) and aluminum ( Al).

The "multi-component" electrodes of some high-capacity batteries are mainly composed of AB2, where A is titanium (Ti) or vanadium (V), and B is zirconium (Zr) or nickel (Ni), plus Some chromium (Cr), cobalt (Co), iron (Fe) and/or manganese (Mn). All of these compounds play the same role: reversibly forming metal hydrides. When the battery is charged, hydrogen ions (H+) in the potassium hydroxide (KOH) electrolyte are released, and they are absorbed by these compounds to avoid the formation of hydrogen (H2) to maintain the pressure and volume inside the battery.

When the battery is discharged, these hydrogen ions will return to their original places through the opposite process.
