Two common types of batteries are:
- Alkaline Batteries: These are the most commonly used batteries, found in devices like remote controls, flashlights, and toys. They are known for their long shelf life and are inexpensive. Alkaline batteries use zinc and manganese dioxide as their electrodes and potassium hydroxide as the electrolyte.
- Lithium Batteries: These batteries are often used in devices that require higher energy, such as smartphones, cameras, and laptops. Lithium batteries are known for their high energy density and long lifespan. They are lighter and more efficient compared to alkaline batteries, but they are also more expensive.
