摘　　要：通过“化学反应与电能”项目式教学的开展,学生能了解原电池结构与功能的关系,进一步完善原电池的结构模型,在此基础上引导学生以铜-锌原电池的结构优化为起点,依据实验现象推断其结构缺陷,提出优化方案。通过液接电势的消除、盐桥向隔膜的演变等后续结构优化方案的创设训练,学生能明确新型电池的优化思路、建立电池设计的思维模型,从而加深对原电池原理的理解、培养运用系统方法解决实际问题的创新思维能力。Through project-based teaching"chemical reaction and electric energy",students can understand the relationship between the structure and function of primary battery,further improve the structural model of primary battery,and on this basis,this paper guides students to take the structural optimization of copper zinc primary battery as the starting point,infer its structural defects based on experimental phenomena,and propose optimization plans.Through the creation training of the subsequent structural optimization scheme,such as the elimination of liquid connection potential and the evolution of salt bridge to diaphragm,students can clarify the optimization idea of new battery and establish the thinking model of battery design,so as to deepen the understanding of the principle of primary battery and cultivate the innovative thinking ability of using systematic methods to solve practical problems.
