Secondary battery electrode, and method for producing same
摘要
說明書
The raw material may include a particulate electrode active material, and the particulate particles may be in the form of a sphere, a flake (scale), an agglomerate, an amorphous shape, a plate, a rod, a crystal (crystal shape composed of thermodynamically stable crystal planes), polyhedron, or a combination thereof, but are not limited thereto.
The electrode active material included in the raw material may include one electrode active material; or two or more electrode active materials having different compositions, crystal structures, particle shapes, mechanical properties, or physical properties. Here, having a different crystal structure also includes a dimorphism case having the same composition and a different crystal structure. In addition, having a different particle shape includes the meaning of having different particle shapes from each other of one material as well as different particle shapes from each other of different materials from each other. As an example, crystal particles of one material (primary particles or crystalline particles) and aggregated particles of the same material (secondary particles), sphere particles of one material and flake particles of the same material, and the like may be included, but which is only suggested for clear understanding, and the present invention is not limited thereto. In addition, the mechanical properties may include one or more selected from the group hardness, strength, toughness, ductility, and the like, and the physical properties may include one or more properties selected from the group comprising electrical conductivity, thermal conductivity, a coefficient of thermal expansion, specific gravity, and the like.
