摘　　要：在证明了阴极极化时阴极电势总是向负移,而阳极极化时阳极电势总是往正移这一基本规律的基础上,在简化条件下,采用电化学热力学和动力学的基本理论简述了电池的充放电曲线的几个基本变化特征:电池电位随着恒流放电时间的延长而降低;电池电位随着放电电流的增大而降低;在电池放电接近完成时,电池电位急剧下降;当电池存在不止一对反应时,充放电时反应发生的次序.The article proves a basic discipline that cathode potential polarized always moves to minus pole,while anode potential polarized always moves to positive pole. In simple conditions, by using basic theories of electrochemical thermodynamics and kinetics,several basic characters of charg-discharge curves were anlyzed： electric potential falls along with the time of constant current discharge. Electric potential falls while current increase. Electric potential falls rapidly when current discharge was almost completed. Charg-discharge of battery has its own order when there are several reactions.
