化学电池在科学技术和日常生活中都有着广泛的应用。我们常用的干电池、钮扣电池、铅蓄电池、用于心脏起搏器的锂电池等都属于化学电池。对此类电池的电极反应式的认识,在近几年高考试题中有所涉及,下面通过对几道例题的分析,谈谈此类试题对创新思 Chemical batteries have a wide range of applications in science and technology and in everyday life. Our commonly used dry batteries, button batteries, lead batteries, and lithium batteries for pacemakers are chemical batteries. The understanding of the electrode reaction type of such batteries has been involved in the examination questions in recent years. The following analysis of a few examples will be used to discuss such questions on innovative thinking.
