5. Ni-MH Battery Chemical Composition
The "metal" portion of a nickel-metal hydride battery is actually a metal hydride.
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) aluminum ( Al).
In some high-capacity batteries, the “multi-composition” electrode is mainly composed of AB2, where A is titanium (Ti) or vanadium (V), and B is zirconium (Zr) or nickel (Ni). Some Cr, Co, Fe, and Mn.
All these compounds play the same role: reversible metal hydride formation. When the battery is charged, hydrogen ions (H+) in the potassium hydroxide (KOH) electrolyte are released and absorbed by these compounds to prevent the formation of hydrogen gas (H2) to maintain the internal pressure and volume of the battery.
When the battery is discharged, these hydrogen ions return to their original place through the opposite process.
