Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a lithium ion battery negative electrode material granulation device. Background Art

[0002] Lithium-ion battery is a secondary battery (rechargeable battery) that mainly relies on the movement of lithium ions between the positive electrode and the negative electrode to work. During the charging and discharging process, Li+ is intercalated and deintercalated back and forth between the two electrodes: when charging, Li+ is deintercalated from the positive electrode and embedded in the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. On October 9, 2019, the Royal Swedish Academy of Sciences announced that the 2019 Nobel Prize in Chemistry was awarded to John Goodenough, Stanley Whittingham and Yoshino Akira in recognition of their contributions to the research and development of lithium-ion batteries. From August 1, 2023, CCC certification management will be implemented for lithium-ion batteries and battery packs. From August 1, 2024, products that have not obtained CCC certification certificates and marked with certification marks shall not be shipped, sold, imported or used in other business activities. Lithium batteries are divided into lithium batteries and lithium-ion batteries. Mobile phones and laptops use lithium-ion batteries, which are commonly referred to as lithium batteries. Batteries generally use materials containing lithium elements as electrodes and are representatives of modern high-performance batteries. However, real lithium batteries are rarely used in daily electronic products due to their high risk. Lithium-ion batteries were first developed by Sony Corporation of Japan in 1990.

[0003] The application number is CN202122654855.4, which discloses a particle testing tool and a battery manufacturing equipment. The particle testing tool includes a base and a test roller. The base includes a mounting platform and a first rotating shaft, the mounting platform can rotate around the first rotating shaft, and the first rotating shaft is perpendicular to the mounting surface of the mounting platform; multiple test rollers are rotatably connected to the mounting platform, and the outer surface of the test roller can store the particles to be tested; wherein the test roller can rotate around its own axis and revolve with the rotation of the base. The particle testing tool and battery manufacturing equipment provided in this application can reduce the risk of impurities entering the battery during the battery production process and improve the battery safety performance.

[0004] Although the above utility model includes a mounting platform and a first rotating shaft through a base, the mounting platform can rotate around the first rotating shaft, and the first rotating shaft is perpendicular to the mounting surface of the mounting platform; multiple test rollers are rotatably connected to the mounting platform, and the outer surface of the test rollers can store the particles to be tested; wherein the test rollers can rotate around their own axes and revolve with the rotation of the base. The particle testing tool and battery manufacturing equipment provided by this application can reduce the risk of impurities entering the battery during the battery production process and improve the battery safety performance, but there is a disadvantage that after the device completes the particle work, the particles produced by it are of different sizes, so that if they are not classified and processed, the quality of the finished product is low.

[0005] Therefore, it is necessary to install a classification component at the bottom of the stirring component, so that after the stirring of the component is completed, the completed particles can be classified into different sizes, so that the synthesized finished product can be of higher quality during subsequent processing.
