New energy battery cover plate assembly

Abstract

The invention discloses a new energy battery cover plate assembly and belongs to the field of battery packs. The new energy battery cover plate assembly comprises a cover plate, wherein an electrode pressing plate is arranged at the upper end of the cover plate; the electrode pressing plate is longitudinally connected with a rivet; a liquid injection opening and a draught fan are arranged in / at the upper end of the cover plate; the lower end of the draught fan is in butt joint with a pipeline; an electrode leading sheet is arranged at the bottom of the cover plate; a limiting groove is formedin the lower end of the cover plate; the lower end of the pipeline is in butt joint with a filter plate; storage grooves are formed in two sides of the filter plate; limiting blocks are arranged in the storage grooves; the limiting blocks are matched with the limiting groove; four groups of bulges are uniformly arranged at the top of the cover plate. According to the cover plate provided by the invention, the cover plate is protected through the rubber bulges which are uniformly arranged at the upper end; when a battery is operated, air is pumped through the draught fan to carry out heat dissipation on a motor; the filter plate is arranged at the lower end of the cover plate and is used for filtering water and impure dust in the air, so as to prevent the battery from being damaged. Meanwhile, in a subsequent maintenance process, the filter plate adopts a detachable structure and post-period washing and replacement are convenient to realize.

Description

technical field [0001] The invention relates to the field of battery components, in particular to a new energy battery cover plate component. Background technique [0002] New energy batteries are generally composed of "lithium battery" groups. Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the 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, due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal had very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the mainstream now. [0003] Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Li-ion batteries do not contain metallic ...
