Abstract:

Polarization effect plays an important role in electrochemistry. The content arrangement in the traditional textbooks, however, always makes college students feel that the polarization effect is unreasonable for many aspects, particularly in the field of energy storage and transformation. They often intend to think that it is best to eliminate or reduce the polarization effect. However, just as one coin has two sides, the existence of polarization effect is double-edged. The reasonable application of polarization effect is introduced in this paper. The examples of application of polarization effect can make college students understand that advantages and disadvantages depend, and reasonable using the polarization effect can bring a significant amount of revenue.

Key words: Polarization effect, Overpotential, Reasonable application
