図1は角形二次電池100の外観斜視図であり、図2は角形二次電池100の構成を示す分解斜視図である。
−第1プレス工程−
図8(a)および図8(b)に示す矩形平板状の素材11aを準備する。
図9(a)に示すように、第1下型41に素材11aを載置し、素材11aの上方に第1上型31を配置する。第1下型41には、第1上型31に突設された円形状の凸部31aよりも径大の円形状の凹部41aが凹設されている。
図10(a)に示すように、第1プレス工程を終了した素材11bを第2下型42に載置し、素材11bの上方に第2上型32を配置する。第2上型32には、素材11bの凹部11b1に嵌入可能な凸部32aが形成され、第2下型42には、素材11bの凸部11b2が嵌入可能な開口42bが形成されている。
図12(a)に示すように、第2プレス工程を終了した素材11cを第3下型43に載置し、素材11cの上面に第3上型33を当接させ、素材11cの上方に第4上型34を配置する。第4上型34には円柱形状の押圧部34aが設けられ、第3上型33には第4上型34の押圧部34aが挿通される開口33aが設けられている。素材11cは、第3上型33と第3下型43とで挟み込まれている。第3下型43には、上記した円筒状の先端側挿通部151b2の形状に対応した平面視円環状の溝43aが設けられている。
図13(a)に示すように、鍛造工程を終了した素材11dを第4下型44に載置し、素材11dの上方に第5上型35を配置する。第5上型35には、上記したボルト131が挿通される貫通孔152aの形状に対応した円柱状の穴抜きパンチ部35aと、負極外部端子105の外形の形状に対応した開口部を有する外形抜きダイ部35bとが設けられている。第4下型44には、第5上型35の穴抜きパンチ部35aが挿通される開口を有する穴抜きダイ部44aと、負極外部端子105の外形の形状に対応した外形抜きパンチ部44bとが設けられている。
抜き加工工程を終了した素材11eのバリや角部を除去すると、図6に示す負極外部端子105が形成される。
このようにして形成された負極外部端子105は、バスバー接続部152の厚さt1や底部151dの厚さt2が、シール部151cの厚さt0よりも薄くなる構成とされる(図14(b)参照)。
なお、上記したように、正極外部端子104についても同様に、第1プレス工程、第2プレス工程、鍛造工程、抜き加工工程、仕上げ加工工程を経て形成される。
(1)外部端子104,105は、それぞれバスバー123が接続されるバスバー接続部142,152と、集電体180,190が接続される集電体接続部141,151とを有している。バスバー接続部142と集電体接続部141とは電池蓋上で一体に並設され、バスバー接続部152と集電体接続部151とは電池蓋上で一体に並設されている。集電体接続部141,151は、それぞれ電池蓋102の貫通孔102hに挿通される筒状の挿通部141b,151bと、挿通部141b,151bの外周に設けられ、貫通孔102hと挿通部141b,151bとの間を封止するガスケット169の鍔部169bを押圧するシール部141c,151cとを有している。筒状の挿通部141b,151bのそれぞれの内側には、電池蓋102の貫通孔102hを封止する底部141d,151dが設けられている。挿通部141b,151bのそれぞれの先端は、集電体180,190にかしめられ、外部端子104,105が集電体180,190を介して捲回電極群170の電極174,175に電気的に接続されている。
(1)上記した実施の形態では、ボルト131の頭部131bを正極側空間および負極側空間のそれぞれに収容した例について説明したが、本発明はこれに限定されない。ボルト131の頭部131bに代えて、ナット132を収容するようにしてもよい。
