Title (EN) ELECTRICITY STORAGE DEVICE
(FR) DISPOSITIF DE STOCKAGE D’ÉLECTRICITÉ
(JA) 蓄電デバイス
Abstract:
(EN) Provided is an electricity storage device which is not susceptible to deterioration in the electricity storage characteristics. With respect to an electricity storage device 1 according to the present invention, a first insulating bonding layer 15a comprises a first portion 15a1 that covers the periphery of a first active material layer 11b and a second portion 15a2 that covers the periphery of a first electrolyte layer 13a. The second portion 15a2 is bonded to a second insulating bonding layer 15b. The second insulating bonding layer 15b comprises a third portion 15b1 that covers the periphery of a second active material layer 12b and a fourth portion 15b2 that covers the periphery of a second electrolyte layer 13b. The fourth portion 15b2 is bonded to the second portion 15a2. The content of an inorganic filler in the second portion 15a2 is lower than the content of the inorganic filler in the first portion 15a1. The content of the inorganic filler in the fourth portion 15b2 is lower than the content of the inorganic filler in the third portion 15b1.
(FR) L'invention concerne un dispositif de stockage d'électricité qui n'est pas sensible à la détérioration des caractéristiques de stockage d'électricité. Par rapport à un dispositif de stockage d'électricité 1 selon la présente invention, une première couche de liaison isolante 15a comprend une première partie 15a1 qui recouvre la périphérie d'une première couche de matériau actif 11b et une seconde partie 15a2 qui recouvre la périphérie d'une première couche d'électrolyte 13a. La seconde partie 15a2 est liée à une seconde couche de liaison isolante 15b. La seconde couche de liaison isolante 15b comprend une troisième partie 15b1 qui recouvre la périphérie d'une seconde couche de matériau actif 12b et une quatrième partie 15b2 qui recouvre la périphérie d'une seconde couche d'électrolyte 13b. La quatrième partie 15b2 est liée à la seconde partie 15a2. La teneur en charge inorganique dans la seconde partie 15a2 est inférieure à la teneur en charge inorganique dans la première partie 15a1. La teneur en charge inorganique dans la quatrième partie 15b2 est inférieure à la teneur en charge inorganique dans la troisième partie 15b1.
(JA) 蓄電特性が劣化し難い蓄電デバイスを提供する。 蓄電デバイス1では、第1の絶縁性接着層15aは、第1の活物質層11bの周囲を覆っている第1の部分15a1と、第1の電解質層13aの周囲を覆っている第2の部分15a2とを有する。第2の部分15a2は、第2の絶縁性接着層15bと接着されている。第2の絶縁性接着層15bは、第2の活物質層12bの周囲を覆っている第3の部分15b1と、第2の電解質層13bの周囲を覆っている第4の部分15b2とを有する。第4の部分15b2は、第2の部分15a2と接着されている。第2の部分15a2における無機フィラーの含有量は、第1の部分15a1における無機フィラーの含有量よりも少ない。第4の部分15b2における無機フィラーの含有量は、第3の部分15b1における無機フィラーの含有量よりも少ない。
