电能可以转变成化学能,化学能同样可以;转成电能。借相于某些化学反应,把化学能直接变成电能的装置叫化学电源或电池。其中,最简单的是原电池。鉴于高中化学教材仅介绍伏特(Volta)电池,未涉及丹尼尔(Daniell)电池,中央统编高二下册征求意见本,也仅介绍伏特电池,故本文仅就伏特电池的制作与演示谈谈自己的体会。
Electric energy can be converted into chemical energy, chemical energy can also be converted into electricity. By using certain chemical reactions, a device that directly converts chemical energy into electrical energy is called a chemical power source or a battery. Among them, the simplest is the primary battery. In view of the fact that the high school chemistry textbook only introduces Volta batteries and does not involve Daniell batteries. The Central Committee compiled the book for the second year of the senior high school. It also introduces only the Volt battery. Therefore, this article only discusses the production and demonstration of the Volt battery. Experience.
