Description
本発明は、電池の蓄電容量と出力を増大させるパッケージ構造をもつ電池、より詳しくは、電池パッケージの大きさは同じでも電池の蓄電容量と出力が増すように、電池ケースの長さと、電池ケース内に収容される電極集成体の長さを、上部接合部を電池ケースの上端に向けて折り曲げて接合部の長さ方向の幅を狭めた分だけ長くした電池、好ましくは、上部接合部に対応する内側のかどの曲率半径を大きくして優れた封止力を実現させた電池、より好ましくは、電池の蓄電容量と出力を更に高めるために、電池ケースの上体部と下体部とを互いに分け、電極集成体を入れるための収容部を上体部と下体部にそれぞれ形成した電池に関するものである。
本発明は上記の問題点を鑑みてなされたものであり、本発明の一つの目的は、電池ケースの収容部の長さ、及び収容部に入れる電極集成体の長さを、電池ケースの上部接合部が電池ケースの縦の方向に占める幅の分だけ長くし、それによって電池パッケージの大きさは同じでも電池の蓄電容量と出力を高めることができるパッケージ構造をもつ電池を提供することである。
(i)上体部の下端が下体部の下端と一体的に形成されていて、収容部が下体部のみに形成された構造、
(ii)上体部と下体部が互いに分かれていて、収容部が下体部に形成された構造、
(iii)上体部と下体部が互いに分かれていて、収容部が上体部と下体部にそれぞれ形成された構造、及び
(iv)上体部の下端が下体部の下端と一体的に形成されていて、収容部が上体部と下体部にそれぞれ形成された構造
からなる群から選ばれる一つの構造をもっていてよい。
さて、添付の図面を参照しながら本発明の好ましい態様を詳しく説明する。
