Abstract
An electrode includes a current collector, an active material layer, a first layer including first particles, and a second layer including second particles, wherein an average cross-sectional area of the first particles in a plane substantially parallel to the electrode surface is smaller than an average cross-sectional area of the second particles in a plane substantially parallel to the electrode surface.

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.
An electrode comprising:
- a current collector;
