Description

Technical Field

[0001] The utility model relates to the technical field of lithium ion batteries, in particular to a negative electrode batching device for lithium ion batteries. Background Art

[0002] Lithium-ion battery is a secondary battery that mainly relies on the movement of lithium ions between the positive electrode and the negative electrode to work. During the charge and discharge process, Li+ is embedded and de-embedded between the two electrodes. According to the different electrolyte materials used in lithium-ion batteries, lithium-ion batteries are divided into liquid lithium-ion batteries, condensed lithium-ion batteries and polymer lithium-ion batteries. Lithium-ion batteries have high energy density, high average output voltage and long service life. They do not contain toxic and harmful substances and are called green batteries.

[0003] In view of this, Chinese Patent No. CN216054796U proposes a lithium-ion battery negative electrode batching device. By providing a first filter, a second filter and a third filter inside the main body of the device, when batching is required for multiple materials, the materials will be mixed with a small amount of impurities. When the materials are poured into the main body of the device, the impurities will be filtered by the first filter, the second filter and the third filter. The first magnetic block and the second magnetic block can be separated. The first filter, the second filter and the third filter are separated from the first support plate, the second support plate and the third support plate respectively. The operator can clean the filtered impurities, which is convenient to use. In the above patents, the negative electrode batching device for lithium-ion batteries performs screening when loading. After loading, the screening residue is separated and moved outward by magnets, which makes it easy to cause the residue to tilt and fall during movement to cause secondary pollution, so that the impurity materials are still easy to be poured into the main body of the device during batching, reducing the practicality of the negative electrode batching device for lithium-ion batteries.
