METHOD OF PRODUCING ELECTRODE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18616326 titled 'METHOD OF PRODUCING ELECTRODE

The abstract describes a patent application for preparing an active material powder containing foreign particles and active material particles, forming a first electrode material with this powder, and performing dry classification treatment to decrease the foreign particles in the electrode material. An active material layer is then formed with the treated electrode material, which is in powder form and includes metal foreign objects as coarse particles.

• Active material powder with foreign particles and active material particles prepared
• First electrode material made with the active material powder

Original Abstract Submitted

An active material powder that includes a foreign particle and an active material particle is prepared. A first electrode material that includes the active material powder is prepared. Dry classification treatment is performed on the first electrode material, and thereby the foreign particle included in the first electrode material is decreased. An active material layer that includes the first electrode material after the dry classification treatment is formed. The first electrode material is in powder form. The foreign particle includes a metal foreign object and is a coarse particle.
