Description
本開示は、電池、より具体的にはリチウム系電池に関する。
充電式リチウムイオン電池は、それらの比エネルギーが他の電気化学的エネルギー貯蔵デバイスに比べて高いため、可搬型の電子機器ならびに電気自動車およびハイブリッド電気自動車のための魅力的なエネルギー貯蔵システムである。以下により十分に議論されるように、典型的なリチウムイオンセルは、負極、正極、および該負極と正極との間にセパレーター領域を含む。両方の電極は、リチウムを可逆的に挿入するか、またはリチウムと反応する活物質を含む。幾つかの場合には、前記負極は、可逆的に電気化学的に溶解および析出しうるリチウム金属を含むことがある。前記セパレーターは、リチウムカチオンを有する電解質を含み、それは電極間の物理障壁として前記セル内で電極が電気的に接続されないように働く。
一実施形態によれば、電気化学的セルは、リチウムの一形態を含む負極と、負極と間隔をおいて配置された正極と、前記負極と前記正極との間に配置されたセパレーターと、前記負極と前記正極との間に配置された第一のリチウムイオン伝導性かつイオン遮断性の複合固体電解質層とを含む。
本開示の原理の理解を促す目的で、図面に図解される実施形態と以下に記載の明細書に記載される実施形態がここで参照されるものとする。本開示の範囲をそれにより制限することを意図するものではないと理解される。更に、本開示は、図解された実施形態に対する任意の変化および変更を含み、更に本開示の属する技術分野における当業者に通常想起されるであろう開示の原理の適用を含む。
