Abstract: In recent years, electrochemical technology has not only advanced progress in energy, environmental protection, and materials science but also enhanced the convenience and security of our daily lives. To bridge the gap between electrochemistry and real-world applications and to elucidate the underlying principles behind observable phenomena, this article introduces key electrochemical concepts in areas such as self-heating packs, the sports industry, and nucleic acid detection. The focus will be on electrochemical corrosion heating, electrochemical energy storage technologies, and the use of graphene nanocomposites in nucleic acid sensors. This paper aims to enhance public understanding of electrochemistry, thereby fostering a deeper comprehension of everyday phenomena and improving scientific literacy.

Key words: Electrochemical corrosion heating, Electrochemical energy storage technology, Electrochemical biosensor
