  • Publication number: 20240332489
    Abstract: This disclosure provides a method of manufacturing an electrode sheet of a lithium-ion liquid battery. An electrode powder is formed from an active material by a dry mixing process. A current collecting metal sheet is disposed in a mold. The electrode powder is introduced into a cavity of the mold on opposite sides of the current collecting metal sheet. A thermal compression process using the mold is performed to form a first and a second electrode layer from the electrode powder, where the two electrode layers are respectively attached to a first and a second surface of the current collecting metal sheet. When a positive electrode sheet is manufactured, densities of the electrode layers are in a range of 1.6 g/cm3 to 3.4 g/cm3. When a negative electrode sheet is manufactured, densities of the electrode layers are in a range of 1.2 g/cm3 to 2.1 g/cm3.
