摘要:
An electrode for an all-solid-state battery is provided. The electrode comprises granules including a core containing an active material, a first conductive material and a binder, and a coating layer containing a solid electrolyte and a second conductive material disposed in contact with an outside of the core. According to one embodiment of the present invention, the first and second conductive materials have different sizes or shapes. The first conductive material has an aspect ratio of 4000 to 6000 and a BET specific surface area of 100 m2/g to 300 m2/g. The second conductive material has an aspect ratio of 100 to 300 and a BET specific surface area of 10 m2/g to 30 m2/g. The granules form an excellent electrical network in the interior of the granules even under the all-solid-state conditions, which contributes to the improvement of the battery performance when applied as an electrode for an all-solid-state battery.
