Alkaline batteries are a type of disposable battery using specific materials and offering distinct advantages.
What Defines an Alkaline Battery?
- Electrode Composition: Alkaline batteries use zinc and manganese dioxide as electrodes.
- Electrolyte: The alkaline electrolyte is either potassium or sodium hydroxide.
- Disposable: They are designed for single use and disposal.
Advantages of Alkaline Batteries
Alkaline batteries offer certain advantages, particularly compared to older technologies like carbon-zinc batteries. These benefits include:
- Steady Voltage: They provide a relatively stable voltage output during their discharge cycle.
- Energy Density: They offer better energy density, meaning they can store more energy for their size.
- Leakage Resistance: They exhibit improved resistance to leakage, reducing the risk of damage to devices.
Summary
In summary, alkaline batteries are disposable batteries characterized by their zinc and manganese dioxide electrodes and alkaline electrolyte. They are favored for their steady voltage, better energy density, and increased leakage resistance
