1. An electrode comprising a current collector, an active material layer, a first layer comprising first particles, and a second layer comprising second particles,
wherein the first particles are amorphous-shaped inorganic particles, the second particles are plate-shaped inorganic particles, each of the first particles has a largest cross-sectional area in a plane substantially parallel to the electrode surface, each of the second particles has a largest cross-sectional area in a plane substantially parallel to the electrode surface, and an average cross-sectional area of the largest cross-sectional areas of the first particles is smaller than an average cross-sectional area of the largest cross-sectional areas of the second particles.
