Lithium battery composite negative electrode material preparation device

Abstract

The invention discloses a lithium battery composite negative electrode material preparation device, and belongs to the technical field of lithium batteries. The device comprises a box body, the upperend of the box body is provided with a material mixing box, the material mixing box is provided with a stirring mechanism, the inner side of the box body is provided with a shaking mechanism, and theshaking mechanism is fixed on the inner wall of the box body through a support rod. The shaking mechanism is connected with the material mixing box and shakes the material mixing box, and a grinding and material mixing mechanism is further arranged on the shaking mechanism. According to the lithium battery composite negative electrode material preparation device, a negative electrode material is stirred and mixed through rotating stirring blades, and meanwhile, a second driving motor drives an eccentric wheel to rotate, so that the eccentric wheel pushes the material mixing box to shake up anddown, the negative electrode material is uniformly mixed in the material mixing box, and the mixing effect of the negative electrode material is good; and the negative electrode material can be mixedagain through a rotating grinding and mixing roller, so that the granularity of the negative electrode material is uniform, the negative electrode material mixing effect is good, and the production and processing requirements of the lithium battery can be met.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a preparation device for composite negative electrode materials for lithium batteries. Background technique [0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and uses a non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, M.S.Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream. [0003] Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Li-ion batteries do not contain metallic lithium and ar...

Problems solved by technology

[0004] During the production and processing of lithium batteries, it is necessary to mix the composite negative electrode materials, but the traditional composite negative electrode material preparation equipment cannot fully mix the composite negative electrode materials, resulting in poor mixing effect of the composite negative electrode materials, which cannot meet the requirements Lithium battery production and processing needs
