Description
Technical Field
[0001] The utility model belongs to the technical field of battery electrodes, and in particular relates to a lithium ion battery electrode structure. Background Art
[0002] Lithium-ion batteries are rechargeable batteries that are widely used in portable electronic devices, electric vehicles, and energy storage systems. They are widely popular mainly because of their high energy density, relatively long cycle life, and low self-discharge rate. The working principle of lithium-ion batteries is based on the movement of lithium ions between the positive and negative electrodes of the battery. During the charging process, lithium ions move from the positive electrode to the negative electrode and are stored in the negative electrode material; during the discharge process, lithium ions move from the negative electrode back to the positive electrode, releasing the stored energy for use by the external circuit. The positive electrode material of the battery is usually composed of lithium metal oxide, such as lithium cobalt oxide, lithium iron phosphate, etc., while the negative electrode material is usually graphite. The electrolyte is the medium for the movement of lithium ions inside the battery, and the diaphragm is a special material that allows lithium ions to pass through but prevents electrons from passing through, ensuring the safe operation of the battery. Compared with other types of rechargeable batteries, such as nickel-cadmium or nickel-metal hydride batteries, lithium-ion batteries have several significant advantages, including higher energy density and longer life.

[0028] Handles 3 are provided on both sides of the outer shell 1, and the two handles 3 are symmetrically arranged. By arranging the handles 3, the entire battery is easy to carry and operate. The nut 42 is threadedly connected to the outside of the electrode column 41, and the wire 43 is fixedly connected to the lower surface of the electrode column 41. By arranging the electrode column 41, it is responsible for realizing the electrical connection of the battery.

Through the above mechanism, the user can accurately adjust the position of the electrode column 41.
