Abstract | This electrode for batteries is provided with: a core material; and a mixture layer which contains an active material and a binder, while being arranged on the surface of the core material. If the mixture layer is trisected in the thickness direction and the divided sections are defined as the first region, the second region and the third region sequentially from the core material side, the void fraction of the second region is higher than the void fraction of the first region.
La présente invention concerne une électrode pour batteries comprenant : un matériau de noyau ; et une couche de mélange qui contient un matériau actif et un liant, tout en étant disposée sur la surface du matériau de noyau. Si la couche de mélange est divisée en trois dans la direction de l'épaisseur et les sections divisées sont définies comme étant la première région, la deuxième région et la troisième région de manière séquentielle à partir du côté de matériau de noyau, la fraction de vide de la deuxième région est supérieure à la fraction de vide de la première région.
電池用電極は、芯材と、活物質および結着材を含み、芯材の表面に設けられた合材層とを備える。合材層を厚み方向に3等分し、芯材側から順に第1領域、第2領域、および第3領域と定義した場合に、第2領域の空隙率が、第1領域の空隙率よりも高い。 |
