Description
この成層化現象は、充電効率の低下→正負両極での粗大硫酸鉛結晶粒の生成(サルフェーション)→濃淡電池形成→自己放電を招き、電池寿命を低下させる。
前記アイドリングストップでは、エンジン停止中は、必要電力は鉛蓄電池から供給され、発進時には速やかにエンジンを始動するため、鉛蓄電池には従来のSLI用途(始動・照明・イグニション)とは比較にならないほど深い充放電が繰り返され、その結果、成層化現象が発生し易くなった。また前記過充電防止システムでは、過充電に至らないためガスが発生しなくなり、その結果、成層化現象が防止されなくなり、このようなことから、電池寿命が著しく短くなった。
本発明は、深い充放電が繰り返されるなどの苛酷な条件で使用しても長寿命で、かつ放電容量が大きい、特にアイドリングストップや過充電防止などの新システムを導入した自動車に適した開放型鉛蓄電池の提供を目的とする。
前記ガラスマットには、面密度が20〜100g/m2、20kPa加圧時の厚みが0.1〜0.8mmのものを使用した。
比重差が0.4以上を成層化発生と判定した。
この試験では過充電には至らず、従って発生ガスによる液撹拌は起きなかった。
実施例1および比較例1〜4の調査結果を表1に示した。
Claims (1)
- Pb−Ca系合金基板を用いた正極板と、負極板とをセパレータを介して交互に積層してなる極板群が電槽内に挿入された自動車用開放型鉛蓄電池において、前記セパレータがフェルト状で、その面密度が20〜100g/m2、20kPa加圧時の厚みが0.1〜0.8mmであり、前記正極板または負極板の少なくとも1つが合成樹脂製の袋に収容されており、前記極板群が電槽内に10〜25kPaの圧迫度で挿入されていることを特徴とする自動車用開放型鉛蓄電池。
