Description
本実施の形態では、本発明の一態様である蓄電装置の電解液である常温溶融塩について説明する。
本発明の一態様である蓄電装置における電解液は、非水溶媒および電解質塩から構成されている。本発明の一態様である常温溶融塩は、電解質塩を溶解させる非水溶媒として用いることができる。そして、非水溶媒に溶解させる電解質塩は、キャリアイオンであるアルカリ金属イオン、アルカリ土類金属イオン、ベリリウムイオン、またはマグネシウムイオンを含む電解質塩であればよい。アルカリ金属イオンとしては、例えば、リチウムイオン、ナトリウムイオン、もしくはカリウムイオンがある。アルカリ土類金属イオンとしては、例えばカルシウムイオン、ストロンチウムイオン、もしくはバリウムイオンがある。本実施の形態では、電解質塩を、リチウムイオンを含んだ電解質塩(以下、含リチウム電解質塩という)とする。さらに、少なくとも正極、負極、およびセパレータを用いることで、リチウムイオン二次電池またはリチウムイオンキャパシタを構成することができる。また、この構成において、電解質塩を用いずに、本発明の一態様である常温溶融塩のみを電解液として用いることで、電気二重層キャパシタとすることができる。
ここで、正極活物質層143を正極集電体142上に有する正極148の作製方法について説明する。
