Manufacturing method of an electrode for electrochemical element and an electrochemical element

摘要

Disclosed is a manufacturing method of an electrode for an electrochemical element having a superior adhesion and is used for an electrochemical element with excellent productivity due to a short predoping time. Specifically disclosed is that the method is characterized by comprising a step for compression forming of electrode material (a mixed powder or composite particles) including an alkaline metal powder or an alkaline earth metal powder each having a coated surface.
