The "metal" portion of a Lithium Manganese Dioxide battery for digital cameras is actually an intermetallic compound. Many types of intermetallic compounds have been used in the manufacture of nickel-hydrogen batteries, and 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.
In terms of the voltage of each unit cell, nickel-metal hydride and nickel-cadmium are both 1.2V, while lithium batteries are indeed 3.6V, and the voltage of lithium batteries is three times that of the other two. And the weight of the same type of battery lithium battery is almost equal to the nickel-cadmium battery, while the nickel-hydrogen battery is relatively heavy. It can be seen that the weight of each battery itself is different, but the lithium battery is reduced by 1/3V, and the number of individual batteries can be reduced by one-third when the output voltage is equal, so that the weight and volume of the battery after molding are reduced.
