Electrode forming coating liquid, electrode and electrochemical element, and electrode forming coating liquid manufacturing method, electrode manufacturing method and electrochemical element manufacturing method

摘要

The coating liquid for forming an electrode in accordance with the present invention includes, as constituents, a granulated particle containing an electrode active material, a conductive auxiliary agent having an electronic conductivity, and a binder capable of binding the electrode active material and conductive auxiliary agent to each other; and a liquid adapted to disperse or dissolve the granulated particle, whereas the granulated particle is formed by way of a granulating step of preparing a material liquid containing the binder, the conductive auxiliary agent, and a solvent, and then attaching the material liquid to a surface of a particle made of the electrode active material and bringing a particle made of the binder and a particle made of the conductive auxiliary agent into close contact with the surface. An electrode is formed by using the coating liquid for forming an electrode, whereas an electrochemical device is equipped with the electrode.
