The invention relates to a whole
pollution-free manufacturing method for an
electrode containing
electrolyte salt. No water or
solvent is led in a productive process of the
electrode, accordingly purity of an
electrode material is guaranteed to the maximum degree, and performance of an electrochemical device is improved. An inner wall of a
pipe in a full-automatic
powder transportation process is made of high-stability and high-wearing inorganic nonmetallic materials, and
pollution caused by contact between electrode
powder materials and
metal is avoided. In all processes comprising
powder handling and
film processing, the electrode materials are not contacted with the
metal in all processes. In addition, the
electrolyte salt is evenly distributed in the electrode in an electrode manufacture process, only an
electrolyte solvent is injected in a hollowing
liquid injection process, and crystallographic problems of the electrolyte salt are solved. Simultaneously, the electrolyte
solvent after
liquid injection forms a high-speed
ion motion channel inside the electrode in a process for dissolving the electrolyte salt, and
power density of the electrochemical energy-saving device is greatly improved.
