Abstract
Description
集電体と、
前記集電体に接している電極層と、
固体電解質を含む固体電解質層と、
封止材料を含む封止層と、
を備え、
前記集電体の焼鈍軟化温度は、前記封止材料のガラス転移温度よりも低い、
電池を提供する。
電池の大面積化、連続生産及び大量生産の観点から、全固体電池の製造に塗工プロセスを適用することが検討されている。塗工プロセスでは、原料粉末を溶媒に分散させることによってスラリーを調製する。スクリーン印刷法、ダイコート法などの塗布方法によってスラリーを集電体に塗布することによって、塗布膜を形成する。乾燥炉などを用いた熱プロセスによって塗布膜から溶媒を揮発させる。これにより、集電体及び電極層を有する電極板が得られる。
本開示の第1態様に係る電池は、
集電体と、
前記集電体に接している電極層と、
固体電解質を含む固体電解質層と、
封止材料を含む封止層と、
を備え、
前記集電体の焼鈍軟化温度は、前記封止材料のガラス転移温度よりも低い。
集電体、電極層及び固体電解質層を含む発電要素をプレス温度まで加熱することと、

前記プレス温度は、前記集電体の焼鈍軟化温度よりも高い。
以下、本開示の実施形態について、図面を参照しながら説明する。本開示は、以下の実施形態に限定されない。
図1Aは、一実施形態に係る全固体電池10の概略断面図である。図1Aに示されるように、全固体電池10は、正極11、負極12、固体電解質層5及び封止層8を備えている。正極11は、正極集電体3及び正極層4を有する。負極12は、負極集電体6及び負極層7を有する。正極集電体3の上に正極層4が配置されている。正極層4は、正極集電体3に接している。負極集電体6の上に負極層7が配置されている。負極層7は、負極集電体6に接している。固体電解質層5は、正極層4と負極層7との間に配置されている。正極層4、固体電解質層5及び負極層7がこの順に積層されている。固体電解質層5は、正極層4及び負極層7のそれぞれに接している。封止層8は、正極集電体3及び負極集電体6に接している。正極層4及び負極層7は、それぞれ、電極層の例である。正極11及び負極12は、それぞれ、電極板の例である。封止層8によれば、全固体電池10の内部への水分の侵入を抑制したり、全固体電池10の構造を維持して正極集電体3と負極集電体6との接触による短絡を防いだりできる。その結果、全固体電池10の機械的強度が確保されうる。
正極11は、正極集電体3及び正極層4を有する。負極12は、負極集電体6及び負極層7を有する。
固体電解質層5の材料は、特に限定されず、活物質の種類及び全固体電池10の用途に応じて、一般的にリチウムイオン電池に用いられるものから適宜選択できる。固体電解質層5の材料として、例えば、硫化物系固体電解質材料、酸化物系固体電解質材料、その他の無機系固体電解質材料、及び有機系固体電解質材料が挙げられる。固体電解質は単独で使用してもよいし、2種類以上を組み合わせて使用してもよい。固体電解質の形状は特に限定されず、例えば、粒子状が挙げられる。固体電解質のサイズも特に限定されない。固体電解質が粒子状であるとき、固体電解質の粒子の平均粒径は、0.01μm以上15μm以下であってもよく、0.2μm以上10μm以下であってもよい。平均粒径は、例えば、粒度分布測定装置を用いて測定されたメジアン径(d50)でありうる。
封止層8を構成する封止材料として、熱可塑性樹脂を用いることができる。熱可塑性樹脂を用いることによって材料選択の幅が広がる。
次に、全固体電池10の製造方法の一例について説明する。図2は、全固体電池10の製造の手順を示している。
