摘要：自放電是堿性蓄電池的一項(xiàng)重要性指標(biāo)，而科學(xué)、簡(jiǎn)便地檢測(cè)方法是保證該指標(biāo)正常的重要途徑。傳統(tǒng)的做法是將電池的電量充足，擱置28天后，測(cè)其實(shí)際容量，計(jì)算電池的自放量，這種方法比較接近實(shí)際情況，但在實(shí)際生產(chǎn)中嚴(yán)重影響了生產(chǎn)的進(jìn)度。本文分析了堿性蓄電池自放電與擱置時(shí)間的關(guān)系，采用同一組樣本，擱置7天、14天、28天后，檢測(cè)其自放電量并進(jìn)行對(duì)比。試驗(yàn)結(jié)果表明：堿性蓄電池的自放電量大部分集中在充電后的前7天，因此，在生產(chǎn)中必須詳細(xì)探索擱置時(shí)間與自放電量的對(duì)應(yīng)關(guān)系，探索擱置28天與擱置7天、14天自放電的不同。制定擱置7天、14天的自放電標(biāo)準(zhǔn)，節(jié)約生產(chǎn)時(shí)間，縮短生產(chǎn)周期，加快資金周轉(zhuǎn)。 敘詞：堿性蓄電池 自放電 擱置時(shí)間 Abstract：Self-discharge were a important characteristies guideline of Cd/Ni storage battery.Guideline of self-discharge require scientific and handy method come true.Conventional method were de regle charge at storage battery,place 28 day at normalk temperature,measuring actual electric quantity,and calculate self-discharge,this method be close to physical truth,but serious influence production plan.Relation of self-discharge and place time were analyzed in this paper,self-discharge of place 7 day,14 day and 28 day proceed contrase.The results of expreiment indicated that self-discharge collect at place ahead 7 day,so must detail explore relation of self-discharge and place time,contrast of self-discharge place 28 day,place 14 day.Enactment of rule place 7 day and place 14 day,cut down production time,horten production cycle,accelerate turnover of capital.
