Description
本例の電池モジュールに含まれる扁平型電池1について、図1および図2を用いて説明する。図1は扁平型電池1の平面図を示し、図2は、図1のA―A線に沿う断面図である。扁平型電池1は、リチウムイオン系、平板状、積層タイプのラミネート型の二次電池(薄型電池)であり、図1および図2に示すように、3枚の正極板11と、5枚のセパレータ12と、3枚の負極板13と、正極タブ14(正極端子)と、負極タブ15(負極端子)と、上部外装部材16と、下部外装部材17と、特に図示しない電解質とから構成されている。
上記のように本例は、複数のスペーサ100を積層することにより形成され、外部コネクタ80と嵌合する嵌合部70と、クリップ部83と係合する係合部102とを有する。これにより、嵌合部70および係合部102を含む部分により、外部コネクタ80が確実に接続されるため、別途、雌コネクタ等や、外部コネクタ80の受け口となる別部材を必要とせず、部品点数の増加を抑制することができる。また本例において、従来からの扁平型電池1の積層工数と同じ工数で、外部コネクタ80の差込口が形成され、一体型電池40、41を積層するだけで当該差込口が形成されるため、生産性に優れた電池モジュール200を提供することができる。
