摘　　要：锌—空电池是一种新型的化学电源 ,在较大电流密度下放电 ,会产生严重的欧姆极化 ,影响电池的放电性能。本文采用方波脉冲电流法 ,对自制的小型锌—空电池进行暂态实验 ,快速而准确地测量出电池的欧姆极化 ,求出电池的欧姆极化内阻值 ,指出如何降低电池的欧姆内阻 ,用以指导电池研制中材料、工艺的选用 。Zn-Air battery is a newtype chemical power supply,which will discharge at the biggish electric current density and lead to a serious ohm polarization and affect the discharge performance of the battery.The passage introduces the square wave pulse electric methods,conducts transient experiments to the homemade minitype Zn-air battery,measures the ohm polarization of the battery quickly and accurately,calculates the ohm polarization inner resitance of the battery,and offers a method to decrease the ohm inner resistence.All those content is to clirect the selection of the material and technics in the battery manufacture and the high-effucuebcy methods of charge-discharge in the usury of battery.
