COATING LIQUID FOR ELECTRODE FORMATION, ELECTRODE, ELECTROCHEMICAL ELEMENT AND PROCESS FOR PRODUCING THESE

摘要

A coating liquid for electrode formation, comprising formed granules, the formed granules composed of an electrode active substance, a conductance aid capable of electron transfer and a binder capable of binding the electrode active substance and the conductance aid electrode together, and a liquid capable of dispersing or dissolving the formed granules. These formed granules are obtained through a granulation process wherein a raw liquid comprising a binder, a conductance aid and a solvent is prepared and subsequently this raw liquid is applied to the surface of grains of electrode active substance so as to cause binder particles and conductance aid particles to adhere to that surface. An electrode is formed from this coating liquid for electrode formation, and an electrochemical element includes this electrode.
