Nickel-metal hydride (NiMH) batteries rely on advanced electrochemical reactions to deliver stable and efficient energy storage. These rechargeable batteries use metal hydride anodes, nickel hydroxide cathodes, and alkaline electrolytes like potassium hydroxide (KOH). This combination ensures high energy density and reliable performance across various applications.
The chemical reactions within NiMH batteries are key to their functionality. At the negative electrode, hydrogen ions interact with the metal hydride, while the positive electrode facilitates the formation of nickel oxyhydroxide. The overall discharge reaction produces energy efficiently, with a total voltage of approximately 1.32V.
Reaction Type | Chemical Reaction | Description |
|---|---|---|
Negative Electrode | H2O + M + e− ⇌ OH− + MH | Describes the reaction at the negative electrode during charge and discharge. |
Positive Electrode | Ni(OH)2 + OH− ⇌ NiO(OH) + H2O + e− | Details the formation of nickel oxyhydroxide at the positive electrode. |
Overall Discharge | NiO(OH) + MH → Ni(OH)2 + M | Summarizes the overall reaction during the discharge process of the battery. |
Redox Potential | Redox potential is approximately -0.83 V for the negative electrode reaction. | Indicates the voltage associated with the reduction process at the negative electrode. |
Total Voltage | E0 = 0.49V – (–0.83V) = 1.32V | Provides the total voltage of the redox reaction during battery operation. |
These chemical properties make NiMH batteries suitable for high-drain devices and industrial applications. Their ability to store energy efficiently under varying conditions ensures consistent performance, even in demanding environments.
