Capacity Ratio of the Negative／Positive Electrodes. In a sealed nickel metal hydride battery，a design
of positive-limited is often used. The excess capacity of the negative electrode affects the pressure greatly in the oxygen recombination reaction．thus the ratio of the capacity of negative／positive electrodes should be critically revised． Fig．2 shows the internal pressure curves of 1 subcell batteries with different K values， which represents the capacity ratio of negative electrode to positive electrode． As seen from Fig．2，the Curves of internal pressure become flatter with the value K increasing．And with a larger K ，adelay of the time point where the gas begins to generate is also shown．As K is between 1.6 and 2.1． pressure is generated at 72％ state of charge(SOC)， and the slope of the curve becomes flatter．While K is larger than 2.5， the internal pressure increases very slowly with time going．However， the waste of active materials in negative electrode is great while the valu

容车量比率负面/正面电极。在一个密封的镍金属氢化物电池，一个设计
正压有限公司是常用的。在产能过剩的负面影响电极压力很大，在氧气重组reaction.thus比例的能力阴性/阳性电极应该批判地修改。图2显示了内部压力曲线1亚电池具有不同的K值，代表容量的比例负电极，以积极的电极。看出，从图2 ，曲线的内部压力变成谄媚与K值increasing.和一个更大的钾， adelay的时间点，而天然气开始产生，是也shown.像K值为1.6和2.1 。压力是产生于72 ％的荷电状态（ SOC ）的，以及边坡的曲线变得flatter.while K值大于2.5 ，内部压力的增长十分缓慢，与时间去。然而，浪费的活性物质在负极是伟大的，而K值是太大.总结所有条件上述情况， K值是选定为1.5-1.7，这是较传统的电池。
