对金属氢化物镍电池和镉镍电池在不同条件下的内阻进行了测试分析。实验发现：金属氢化物镍电池和镉镍电池的荷电态内阻小于放电态内阻，且镉镍电池的放电态内阻离散性较大。金属氢化物镍电池荷电态内阻随荷电量的变化存在最小值；金属氢化物镍电池和镉镍电池在长时间放电态贮存过程中，电池内阻都会增加，镉镍电池的内阻增加更明显，且离散性更大；但电池经过充放电活化后，电池内阻可大大降低。同批次生产的相同规格的电池，电池内阻越小，电池的放电电压平台越高。实验还发现，电池的集流体结构设计、隔膜的选择及电液量的多少都会影响电池的内阻。

The internal resistances of Ni-MH and Ni-Cd battery in different conditions were tested and analyzed． The results show that the charged Ni-MH and Ni-Cd batteries have lower resistance than the discharged batteries， and the discharged resistance of Ni-Cd battery is more dispersed． the charged resistance of Ni-MH battery shows the least value according to the charged capacity． the resistances of Ni-MH and Ni-Cd battery are increasing while the battery is stored for a long time in discharged condition， and that of Ni-Cd battery increased and dispersed more evidently． But the resistance of battery decreased greatly after the battery is activated by several charge and discharge cycles． If the battery is produced in the same batch and has the same specification， the less of the resistance the higher of the discharge voltage plateau． And connector design，separator and electrolyte volume are also influenced battery resistance．
