Electrode, secondary battery, battery pack, and vehicle

Abstract

According to one embodiment, an electrode is provided. The electrode includes an active material-containing layer containing active material particles, ferroelectric particles, and solid electrolyte particles. A ratio (FEcontact) of the number of the ferroelectric particles in contact with the active material particles relative to the number of the ferroelectric particles included in the active material-containing layer is 85% or more. A ratio (SEnon-contact) of the number of the solid electrolyte particles not in contact with the active material particles relative to the number of the solid electrolyte particles included in the active material-containing layer is 30% or more.

Dependencies are inferred from the claim text.
