Abstract
【解決手段】扁平袋状に成形された外装体11内にシート状の正極20と負極30がセパレーター40aを介して積層された平板状の電極体10が電解液とともに密封されてなり、前記セパレーターは、シート状の基材41の少なくとも表裏一方の面に接着層42が形成され、前記外装体は、対面するラミネートフィルム(11a、11b)を周回する枠状の周縁領域12が熱圧着によって溶着され、前記電極体は前記周縁領域の内方に配置され、前記周縁領域は、内周側が前記セパレーターの周縁部43を介して溶着されているラミネート型蓄電素子としている。
【選択図】図3
Description
前記セパレーターは、シート状の基材の少なくとも表裏一方の面に接着層が形成され、
前記外装体は、対面するラミネートフィルムを周回する枠状の周縁領域が熱圧着によって溶着され、
前記電極体は前記周縁領域の内方に配置され、
前記周縁領域は、内周側が前記セパレーターの周縁部を介して溶着されている、
ことを特徴とするラミネート型蓄電素子としている。
本発明の実施例に係るラミネート型蓄電素子の外観や基本的な構成は、図1に示したラミネート型蓄電素子1と同様である。しかし、セパレーターの構造と外装体の封止構造が従来からある一般的なラミネート型蓄電素子とは異なっている。図3は本発明の実施例に係るラミネート型蓄電素子の内部構造を示す図である。図3(A)〜(D)は、いずれも図1(A)におけるa−a矢視断面に相当する図である。図3(A)は、図1に示した従来のラミネート型蓄電素子の内部構造を示す断面図であり、図3(B)、および図3(C)は、本発明の実施例に係るラミネート型蓄電素子1aに用いられるセパレーター40a、および一般的なラミネート型蓄電素子1に用いられるセパレーター40のそれぞれの構造を示す断面図である。また、図3(D)は本発明の実施例に係るラミネート型蓄電素子1aの内部構造を示す図である。
上記サンプルとして、図3(D)に示した実施例に係るラミネート型蓄電素子1aと、実施例に対して比較例となるラミネート型蓄電素子とを作製した。比較例に係るラミネート型蓄電素子としては、図1や図3(A)に示した従来の一般的なラミネート型蓄電素子1に相当する第1の比較例に係るラミネート型蓄電素子と、第1の比較例に係るラミネート型蓄電素子に対し、表面に接着層が形成されたセパレーターを用いている点が異なっている第2の比較例に係るラミネート型蓄電素子を作製した。
上記実施例に係るラミネート型蓄電素子に用いたセパレーターは、基材の表裏両面に接着層が形成されていたが、表裏一方の面に形成されていてもよい。そして、セパレーターの周縁部が外装体の周縁領域の内周側に介在して、当該周縁部がラミネートフィルムの内面に溶着されていればよい。
11a,11b ラミネートフィルム、12 周縁領域、13 端子側縁辺、
20 正極、30 負極、40,40a,40b セパレーター、
41 セパレーターの基材、42 セパレーターの接着層、
43 セパレーターの周縁部、110 電極体の積層部
