In terms of performance, carbon-zinc cells are generally surpassed by which type of cell?

The alkaline cell generally surpasses carbon-zinc cells in performance due to several key factors. Alkaline cells utilize a potassium hydroxide electrolyte, which allows for more efficient chemical reactions compared to the acidic electrolyte used in carbon-zinc cells. This improved chemistry results in a higher energy density, longer shelf life, and a greater capacity to deliver power over extended periods.

Moreover, alkaline cells are designed to handle higher rates of discharge, making them more suitable for high-drain applications. They also have a reduced internal resistance, contributing to better overall efficiency. Thus, for applications requiring consistent and prolonged power, alkaline cells are a superior choice in comparison to carbon-zinc cells.
