Description
蓄電デバイス50は、図5に示すように、複数の正極板10と複数の負極板20とを有し、正極板10と負極板20とがセパレータ30を挟んで交互に積層された電極体が、電解液45(イオン伝導体)とともにラミネート部材40に包まれて密封されている。また、以下の説明では、イオン伝導体として電解液45としているが、正極板10、負極板20、イオン伝導体(45)の全てを固体とする全固体電池等であってもよい。また、密封する容器として、積層物(ラミネート)に限らず、ステンレスやアルミニウム等の金属を用いてもよい。
上記に説明した蓄電デバイス50を車両用として利用するためには、複数の蓄電デバイス50を積層した蓄電デバイス積層体として利用する。また、積層の際、磁界発生手段とともに積層する。例えば図6及び図7に示すように、蓄電デバイス積層体70は、一定方向の磁力線を発生する磁界発生手段60と、蓄電デバイス50と、が交互に積層されて構成されている。
次に図10を用いて、磁力線Mによる磁場(磁界)の効果について、以下の(1)〜(7)に説明し、当該(1)〜(7)を図10中にも示す。なお図10中において、符号80は溶媒和を示し、符号81はリチウムイオン(陽イオン)を示し、符号82は電解質イオン(陰イオン)を示し、符号83は溶媒分子を示し、符号84は固体電解質膜を示している。
(1)活物質層、導電助剤(活物質層中に含まれている)、金属箔等の電気伝導度を増加させる。
(2)電解液45のイオン伝導度を増加させる。
(3)活性炭(正極活物質層)の微細な孔の中を、電解液、リチウムイオン81(陽イオン)、電解質イオン82(陰イオン)が、移動する速度を増加させる。
(4)電解液中の溶媒和80からリチウムイオン81が脱離する反応と、負極板20から放出されたリチウムイオン81を受け取り、再び溶媒和80を形成する反応と、に要するエネルギーを低下(溶媒和の脱離/形成に要するエネルギーを低下)させることで、反応速度を増加させる。
(5)リチウムイオン81が、固体電解質膜84を通過する速度を増加させる。
(6)黒鉛(負極活物質層)の六角板状結晶の層と層との間を、正極板10と対向する方向にそろえ、リチウムイオン81の挿入速度及び脱離速度である反応速度を増加させる。
(7)負極板20に向けて固体電解質膜84を通過したリチウムイオン81を、黒鉛内部方向にすぐに拡散させ、リチウムイオン81の受け入れ性を向上させ、リチウムイオン81の挿入速度、及び脱離速度である反応速度を増加させる。
