Description
生成したH3PO4は、電池パック内の金属部品の表面に燐酸皮膜を形成する。その際、金属表面とH3PO4が反応してH2が生成するため、H2Oの分解が促進され、水分濃度を低下させることができる。金属部品には、例えば、筐体2の内壁、電圧検出端子、電圧検出端子のネジ止め部、ネジ、ワッシャー等が挙げられる。電池12の正極端子16又は負極端子17に電圧検出端子をネジ止めで固定する場合に、部品間の隙間に燐酸皮膜が生成すると、燐酸皮膜は絶縁体のため、部品間の導通が寸断される。ネジ、ネジ止め部及びワッシャーの表面を導電性プラスチックで被覆することによって、これら部品への燐酸皮膜の形成を抑えることができるため、部品間の導通を維持することができる。
Na2O+H2O→2NaOH (3)
CaO+H2O→Ca(OH)2 (4)
MgO+H2O→Mg(OH)2 (5)
また、吸湿材は、電池から発生する炭酸ガスと反応して炭酸ガスを吸収することができる。吸湿材による炭酸ガス吸収反応の一例を(6)〜(9)に示す。
Na2O+CO2→Na2CO3 (7)
CaO+CO2→CaCO3 (8)
MgO+CO2→MgCO3 (9)
吸湿剤が吸湿して発生した水酸化物、例えば、LiOH、NaOH、Ca(OH)2、Mg(OH)2などの水酸化物は炭酸ガスを吸収して水分を放出する。LiOHの場合の反応式を(10)に示す。
絶縁油4は、吸湿剤が吸湿して発生した水酸化物と反応し、水酸化物濃度を下げることができる。これにより、吸湿剤による吸湿効果を改善することができると共に、吸湿剤が反応して生成した水酸化物が炭酸ガスと反応して水分を放出するのを防止することができる。水酸化物との反応剤として機能する絶縁油には、例えば、燐酸トリオクチル(TOP)、燐酸トリブチル(TOB)、燐酸トリフェニル、燐酸トリメチル、燐酸トリプロピルなどの燐酸エステルを挙げることができる。水酸化物との反応例を下記(11)に示す。
絶縁油の中でも、燐酸トリオクチル(TOP)又は燐酸トリブチル(TOB)が好ましい。TOP、TOBは、冷却油として機能するだけではなく、吸湿剤が吸湿して発生した水酸化物との反応性に優れているからである。
この負極20は、負極集電体20aと、負極活物質含有層20bとを有する。負極活物質含有層20bは、負極集電体20aの片面もしくは両面に担持され、負極活物質、導電剤および結着剤を含む。
この正極19は、正極集電体19aと、正極活物質含有層19bとを有する。正極活物質含有層19bは、正極集電体19aの片面もしくは両面に担持され、正極活物質、導電剤および結着剤を含む。
電解液は、電解質を有機溶媒に溶解することにより調製される。電解質濃度は、0.5〜2mol/Lの範囲内にすることができる。
セパレータ21としては、例えば、合成樹脂製不織布、ポリエチレン多孔質フィルム、ポリプロピレン多孔質フィルムなどを用いることができる。
