Description
本開示の一態様に係る電池の製造方法は、第1金属を含む第1集電体、第1活物質層、固体電解質層、第2活物質層、及び、前記第1金属よりも硬い第2金属を含む第2集電体がこの順に積層された発電要素を準備する準備工程と、前記第1金属よりも硬い第1材料で構成され、粗面化された表面を有する板状部材を介して前記発電要素をプレスするプレス工程と、を含み、前記プレス工程では、前記第1集電体の主面に前記板状部材の前記粗面化された表面を接触させて前記発電要素をプレスする。
[電池の構成]
まず、本実施の形態に係る電池について説明する。
次に、本実施の形態に係る電池100の製造方法の一例を説明する。
まず、電池100の製造方法では、準備工程が行われる。図3に示されるように、準備工程では、第1金属を含む正極集電体11、正極活物質層12、固体電解質層15、負極活物質層14、及び、第1金属よりも硬い第2金属を含む負極集電体13がこの順に積層された発電要素30を準備する(ステップS11)。
次に、電池100の製造方法では、プレス工程が行われる。図4Aは、電池100の製造方法におけるプレス工程を説明するための模式図である。図4Aでは、板状部材18を介して発電要素30をプレスする直前の状態が示されている。図4Bは、電池100の製造方法におけるプレス工程でのプレス初期の板状部材18及び正極集電体11を示す模式図である。図4Cは、電池100の製造方法におけるプレス工程でのプレス後の板状部材18及び正極集電体11を示す模式図である。図4B及び図4Cは、正極集電体11と板状部材18との接触界面近傍を示す拡大断面図である。図3及び図4Aに示されるように、プレス工程では、粗面化された表面18aを有し、第1金属よりも硬い第1材料で構成される板状部材18を介して発電要素30をプレスする(ステップS12)。また、プレス工程では、正極集電体11の主面に板状部材18の粗面化された表面18aを接触させて発電要素30をプレスする。これにより、詳細は後述するが、正極集電体11が板状部材18に拘束された状態で、発電要素30がプレスされる。
次に、電池100の製造方法では、剥離工程が行われる。図3に示されるように、剥離工程では、プレス工程ののちに、プレス工程でプレスされた発電要素30から、板状部材18を剥離する(ステップS13)。具体的には、板状部材18を、平面視における発電要素30の角から丁寧にはがすことで、板状部材18と正極集電体11とを剥離する。角から対角側方向へ板状部材18を剥離することにより、図4Cに示される正極集電体11と板状部材18との接触界面近傍の微細な亀裂19を主な剥離面としながら、発電要素30を破損させることなく取り除くことができる。板状部材18の表面18aの複数の凸部16aは、プレス後には正極集電体11の主面11aに食い込んで、第1金属よりも硬い第1材料で構成される複数の付着物16として残留し、複数の付着物16が正極集電体11の主面11aへ固着される。また、正極集電体11の主面11a近傍にも亀裂19が残存する場合もある。
次に、電池100の製造方法では、切断工程が行われる。図3に示されるように、切断工程では、プレス工程ののちに、発電要素30を切断する(ステップS14)。切断工程では、具体的には、約50℃以上100℃以下に発電要素30を加温した後、正極集電体11を上側にして、外周4辺近傍をそれぞれの辺に沿って、上側からカッター刃で垂直に切り落とす。これにより、電池100が得られる。このような切断工程により、歪及び変形等が生じやすいプレスされた発電要素30の外周部を除去できるため、反りが抑制されて形状精度の高い電池100を、任意の形状で得ることができる。また、準備工程で準備する発電要素30の大きさを大きくした場合には、一連の製造工程から、高精度形状の電池を多数個製造することができる。

以下では、実施の形態の変形例2について説明する。なお、以下の変形例2の説明において、実施の形態及び実施の形態の変形例1との相違点を中心に説明し、共通点の説明を省略又は簡略化する。
以下では、実施の形態の変形例3について説明する。なお、以下の変形例3の説明において、実施の形態との相違点を中心に説明し、共通点の説明を省略又は簡略化する。
以下では、実施の形態の変形例4について説明する。なお、以下の変形例4の説明において、実施の形態及び実施の形態の変形例1から変形例3との相違点を中心に説明し、共通点の説明を省略又は簡略化する。
以下では、実施の形態の変形例5について説明する。なお、以下の変形例5の説明において、実施の形態及び実施の形態の変形例1から変形例4との相違点を中心に説明し、共通点の説明を省略又は簡略化する。
