A new type of battery electrode plate preparation method is described. The method can include the following steps: a) a mixing process; b) a milling and polishing process; c) an extrusion shearing and extending process; d) cutting to obtain an electrode membrane; and e) pressing at a high temperature and a high pressure to obtain a battery electrode plate. The method can adopt the active material of different electrochemical batteries as the main body to prepare a thick type battery electrode plate with a high conductivity, a high capacity and a high active material loading, which has a viscoelastic body. The electrode plate can have a flexible organic network structure and an excellent mechanical strength, and can still exist in a variety of electrolytes after hundreds of times or even thousands of times of deep charge and discharge cycles. The thick electrode plate prepared by using the method can be applied to a variety of batteries such as lead-acid battery positive and negative electrode plates, a lead carbon battery electrode plate, a lithium ion battery electrode plate, a supercapacitor electrode plate, a Ni-MH battery electrode plate, and others. |
