Title (EN) SUPERCAPACITOR
(FR) SUPERCONDENSATEUR
(JA) スーパーキャパシタ
Abstract:
(EN) This supercapacitor is characterized by having a three-layer structure composed of: a metal oxide layer capable of storing oxygen ions between lattices; a metal oxide layer which is oxygen-conductive; and a metal oxide layer serving as an oxygen supply source. Furthermore, it is preferable that the metal oxide layer capable of storing oxygen ions between lattices is one selected from among lanthanum oxide (La2O3), hafnium oxide (HfO2), and zirconium oxide (ZrO2). In addition, it is preferable that the metal oxide layer, which is oxygen-conductive, is one selected from among cerium oxide (CeO2) and yttrium-stabilized zirconia (YSZ).
(FR) L'invention concerne un supercondensateur qui est caractérisé en ce qu'il a une structure à trois couches composée : d'une couche d'oxyde métallique capable de stocker des ions oxygène entre des réseaux; d'une couche d'oxyde métallique qui est conductrice d'oxygène; et d'une couche d'oxyde métallique servant de source d'alimentation en oxygène. En outre, il est préférable que la couche d'oxyde métallique capable de stocker des ions oxygène entre des réseaux soit choisie parmi l'oxyde de lanthane (La2O3), l'oxyde d'hafnium (HfO2), et l'oxyde de zirconium (ZrO2). De plus, il est préférable que la couche d'oxyde métallique, qui est conductrice d'oxygène, soit choisie parmi l'oxyde de cérium (CeO2) et la zircone stabilisée à l'yttrium (YSZ).
(JA) スーパーキャパシタは、格子間に酸素イオンを貯蔵できる金属酸化物層と、酸素導電する金属酸化物層と、酸素供給源となる金属酸化物層の3層構造を有することを特徴とする。また、格子間に酸素イオンを貯蔵できる金属酸化物層が、酸化ランタン(La)、酸化ハフニウム(HfO)、酸化ジルコニウム(ZrO)から選ばれる1種であることが好ましい。また、酸素導電する金属酸化物層が、酸化セリウム(CeO)、イットリウム安定化ジルコニア(YSZ)から選ばれる1種であることが好ましい。
