Solvent-free preparation method of electrode for electrochemical energy storage device

The invention relates to a solvent-free preparation method of an electrode for an electrochemical energy storage device, which comprises the following steps: putting polymer binder powder into electric polarization equipment, and carrying out electric standing polarization treatment on the polymer binder to obtain an electric standing polarization polymer binder; putting the electric electret polarized polymer binder, an electrode active substance and a conductive agent into mixing equipment, and uniformly mixing to obtain an electrode master batch; placing the electrode master batch in a blank pressing machine, and after blank pressing, placing the electrode master batch in a plunger type extruder to extrude an electrode master batch sample strip; rolling the electrode master batch samplestrip into an electrode master batch diaphragm in a calender; and placing the electrode master batch diaphragm in vapor deposition equipment, and depositing a layer of metal collector with the thickness of 10nm-5[mu]m on the
