摘要:

电极极化是一个非常重要的电化学现象,但是传统物理化学教材中该部分内容的编排容易让学生对电极极化现象形成偏见,认为应当尽量减小或者消除极化现象。本文重点介绍了人们对于电极极化现象的合理应用,说明极化现象的存在有利有弊,合理利用极化现象,会为我们的生产和生活带来巨大的收益。

关键词: 电极极化, 超电势, 合理应用

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
