Abstract
【解決手段】負極作用物質2としてリチウム、ナトリウム、カリウムなどのアルカリ金属またはその合金を用い、正極作用物質14として常温で液体である塩化チオニル、塩化スルフリル、塩化ホスホリルなどのオキシハロゲン化物を用い、底部を有する電池缶1内に負極作用物質および正極作用物質を収納して密封口されている液体作用物質電池であって、電池缶底部内面に金属板16を、電池缶底部内面との間に一部空間が形成されるように溶接したことにより、外部端子17を溶接した際に溶接熱が直接負極作用物質に伝わらないようにした。
【選択図】図1
Description
(実施例1)
図1に本発明の実施例1の電池の断面図を示す。図1は、負極作用物質にリチウム、正極作用物質に塩化チオニルを用いた、1/2AAサイズの塩化チオニル・リチウム電池の断面図である。また図2に同じく電池缶底部の断面拡大図を、図3に本発明の実施例及び比較例の電池の電池底面図をそれぞれ示す。
ここで16は板厚0.3mmのステンレス製の金属板であり、電池缶1に金属リチウム2を圧着する前の工程で電池缶1の底部内面にスポット溶接を行い固定している。金属板16は外径φ12.8mm、内径φ4mmのリング状であり、缶内底面と金属板の内円部との間に0.3mmの空間ができる様に、金属板の中央部ににφ9mmの皿状の隆起部が設けられている。電池缶との溶接は金属板のフランジ部分で行っている。この金属板は予め溶接により電池缶に固定されているため、次工程のリチウム圧着工程でも金属板がずれることがなく、量産性の点からも優れている。
金属リチウム2を意図的に電池底面よりにずらして電池缶に圧着し、図4に示す断面拡大図のように金属リチウムを電池缶底面にはみ出させた。それ以外は実施例1と同様にして、電池を1000個製作した。
金属板の断面形状を図5の断面拡大図に示すように、周辺部を電池缶側に突き出すように凸部を設けた形状に替えた以外は実施例2と同様にして、電池を1000個製作した。電池缶と金属板の溶接はこの金属板の凹部で行っている。
金属板及び電池缶底面の断面形状を、図6の断面拡大図に示すように金属板をフラット形状とし、電池缶を金属板との間に隙間ができるように凸部のある形とした。それ以外は実施例2と同様にして、電池を1000個製作した。この場合、電池缶と金属板との空間は0.6mmであり、電池缶と金属板の溶接はこの電池缶の凸部で行った。
図5の断面拡大図に示す断面形状の金属板を、電池缶内径とほぼ同一の寸法とし、電池缶底部へ圧入した以外は、実施例2と同様にして電池1000個を製作した。
金属板を用いなかったこと以外は実施例2と同様にして、図7の断面拡大図に示すような電池を1000個製作した。
金属板の形状をフラット形状とし、図8の断面拡大図に示すように金属板と電池缶底面の間に隙間を設けなかった。それ以外は実施例2と同様に電池を1000個製作した。
金属板の替わりにポリテトラフルオロエチレンからなるフラット形状の樹脂板を用いた。それ以外は比較例2と同様に電池を1000個製作した。
