Abstract
A cathode includes a cathode collector layer, and a cathode active material layer on a surface of the cathode collector layer. The cathode active material layer includes a sintered polycrystalline material having a plurality of crystal grains of a lithium-based oxide, and each of the plurality of crystal grains includes a seed template, and a matrix crystal around the seed template, where the seed template is a single crystal and having a shape of a plate.
