description The invention discloses a continuous preparation method of a self-supporting dry method electrode plate and a preparation device thereof, belongs to the technical field of battery electrodes, does not need to use a binder or other conductive additives in the preparation process, and can solve the problem that when an existing electrode plate is prepared by adopting a dry method process, the preparation cost is low. The process difficulty is high, and the prepared battery has the risk of fire and explosion. The method comprises the following steps: S1, preparing micron-sized active material powder and carbon nanotube aerogel; s2, respectively preparing a composite membrane and a compound according to the active material powder and the carbon nanotube aerogel; s3, rolling and compounding the composite membrane and the compound to form a dry-method electrode plate; and S4, attaching a diaphragm to the surface of the dry-method electrode pole piece and continuously rolling to form an electrode pole piece roll.
