The invention discloses a battery electrode plate viscoelastic raw material, a raw material preparation method and an electrode plate preparation method, and belongs to the field of battery manufacturing. Production and manufacturing of a thick-film electrode plate are completed by design of viscoelastic raw material with unique solid content being 40-80% and visco-elasticity being 1,000-5,000MPa.And automatic fabrication of the battery electrode plate is completed by processes of high-speed mixing of the raw materials, raw material kneading after mixing, extrusion and formation, film preparation, dry coating and rolling formation and electrode plate fabrication. Compared with an existing kneading and mixing process, the carrying capacity range of a battery electrode plate active substance is (0.1-0.7)g/cm<2>, the dosage of an auxiliary material is reduced during fabrication, the automation is high, and the production efficiency and the electrode plate consistency are also improved.
