镍氢电池正负极活性物配比对电池内压的影响

Impact of Ratio of Anode/Cathode Active Materials on Internal Pressure of MH-Ni Batteries

本文使用电池内压测试仪测量了不同正负极配比的镍氢电池在充电时的内压情况,研究正负极配比对电池内压的影响,从而通过电池内压的变化来评估电池的性能。

In this paper, internal pressure detector is used to measure the internal pressure of the metal hydridenickel battery（MH-Ni） battery with the different ratio of anode/cathode materials. The impacts of the ratio of anode/cathode materials on the internal pressure are analyzed, and the capability of the battery is evaluated by testing the changes of the internal pressure.
