Abstract:
(EN) A method for manufacturing an electrochemical device electrode containing a current collector 9, 11 and an active material layer 10, 12 uses four die heads 15a-15d. The active material layer 10, 12 contains a lower active material layer 10a, 12a and an upper active material layer 10b, 12b. While the current collector 9, 11 is conveyed, a slurry is discharged from the die head 15a, which is the most upstream die head in the conveyance direction S, and the die head 15b, which is the second die head from the upstream side, so as to form the lower active material layers 10a, 12a of two electrodes, and a slurry is discharged from the die head 15c, which is the third die head from the upstream side, and the die head 15d, which is the fourth die head from the upstream side, so as to form the upper active material layers 10b, 12b of two electrodes.
(FR) Un procédé de fabrication d'une électrode de dispositif électrochimique contenant un collecteur de courant 9, 11 et une couche de matière active 10, 12 utilise quatre filières 15a-15d. La couche de matière active 10, 12 contient une couche de matière active inférieure 10a, 12a et une couche de matière active supérieure 10b, 12b. Tandis que le collecteur de courant 9, 11 est transporté, une boue est déchargée à partir de la filière 15a, qui est la filière la plus en amont dans la direction de transport S, et de la filière 15b, qui est la deuxième filière à partir du côté amont, de façon à former les couches de matière active inférieures 10a, 12a de deux électrodes, et une boue est déchargée à partir de la filière 15c, qui est la troisième filière à partir du côté amont, et de la filière 15d, qui est la quatrième filière à partir du côté amont, de manière à former les couches de matière active supérieures 10b, 12b de deux électrodes.
(JA) 集電体9,11と活物質層10,12とを含み、活物質層10,12は下活物質層10a,12aと上活物質層10b,12bとを含む、電気化学デバイス用電極の製造方法が、4つのダイヘッド15a~15dを用いる。集電体9,11を搬送しながら、搬送方向Sの最も上流側のダイヘッド15aと上流側から2番目のダイヘッド15bとからスラリーを吐出して、2つの電極の下活物質層10a,12aを形成し、上流側から3番目のダイヘッド15cと上流側から4番目のダイヘッド15dとからスラリーを吐出して、2つの電極の上活物質層10b,12bを形成する。
