Key Differences
Alkaline Batteries are named after the alkaline electrolyte they use, primarily made of potassium hydroxide. On the other hand, Lithium Batteries are based on lithium compounds which act as the battery's anode. Both have unique characteristics and applications.
The primary advantage of Alkaline Batteries is their affordability. They are commonly used in household items like remote controls and toys. Lithium Batteries, in contrast, are often pricier but come with a much longer lifespan, making them a preferred choice for devices like cameras or smartphones.
When it comes to weight, Alkaline Batteries tend to be heavier compared to Lithium Batteries. This is why most portable electronics prefer the lightweight nature of Lithium Batteries. Additionally, Lithium Batteries usually have a higher energy density, offering more power in a smaller size.
The disposal of Alkaline Batteries is less of a concern, as many are free of hazardous materials. Lithium Batteries, however, require more careful disposal due to their chemical composition. It's essential to recycle them properly to avoid environmental damage.
