Description
<全固体電池の全体構成>
図1は、実施の形態1に係る全固体電池の全体構成の一例を概略的に示す断面図である。図1を参照して、複数の全固体電池(以下、「電池」と略す)1の各々は、平板形状を有する。図1に示す例では、複数の電池100を厚さ方向(z方向)に積層するとともに電気的に接続することで、組電池200が構成されている。
固体電極体6は、正極層1と、負極層2と、固体電解質層3と、集電体4と、絶縁フィルム5とを含む。固体電極体6は、積層型の電極体であり、正極層1、固体電解質層3および負極層2が積層されることにより形成されている。固体電極体6は、正極層1、固体電解質層3および負極層2の各々を1層以上含む限り、任意の積層構造を有し得る。たとえば、正極層1、固体電解質層3および負極層2がこの順で積層されることにより、固体電極体6が形成されていてもよい。
以上のように構成された電池100に対して外部刺激が加わる状況、より具体的には、外部から異物X(たとえば金属異物)が押し当てられる状況が生じ得る。図3には、ラミネートフィルム7の表面に対して角度θの方向から異物Xが押し当てられる状況が示されている。異物Xが鋭利な先端形状(針状)を有する場合、異物Xがラミネートフィルム7を貫通し得る。この際、異物Xの先端がラミネートフィルム7に接触してからラミネートフィルム7を貫通するまでの間、ラミネートフィルム7内に収容された固体電極体6にはラミネートフィルム7を通して圧力が印加される。固体電極体6のうちラミネートフィルム7を通して圧力が印加される部分の面積は、異物Xの先端の面積よりも広い。その結果、広範囲に圧力(面圧)が印加されることで、固体電極体6が割れたり砕けたりする可能性がある。
実施の形態1では、金属箔71に少なくとも1つの貫通孔THが形成されている例について説明した。しかし、異物Xが貫通しやすいようにラミネートフィルムが脆弱になっているのであれば他の構成も採用できる。実施の形態2においては、金属箔を被覆する樹脂フィルムが異物Xの貫通に対して脆弱になっている構成について説明する。
最後に、本発明者らが実施した評価試験の結果について説明する。評価試験では、異物Xとして直径3mmの釘を用いた。異物Xがラミネートフィルム7の表面に対して押し当てられる角度θ(図3参照)を45°とした。異物Xの移動速度を秒速2mmに設定した。実施の形態1に係る電池100および実施の形態2に係る電池100Aの試験開始時のSOC(State Of Charge)を100%に設定した。各電池の電圧が2mV低下して時点え異物Xの移動を停止した。異物Xの押し当て位置から1cmの位置の温度を測定した。評価試験は室温環境下で実施した。
