Abstract

The invention discloses a power battery cover plate and a manufacturing method thereof. The power battery cover plate includes a substrate, two electrode columns and two sealing layers; the substrateis spaced with two through holes; and the two electrode columns respectively pass through one through hole; the sealing layers are respectively arranged between the substrate and the electrode columnsthrough injection molding processing. The corresponding through holes and the parts of the substrate at the peripheries of the corresponding grooves are wrapped through each sealing layer, so that the substrate can be tightly connected to the two electrode columns, gas and liquid can be further and effectively blocked to pass through the two through holes when the power battery cover plate is combined with a shell, and the disadvantages of various parts and complex assembling of existing power battery cover plates and incomplete blocking of the gas and liquid can be effectively improved, andtherefore, the power battery cover plate and the manufacturing method thereof can be provided.

Description

technical field [0001] The invention relates to a power battery cover plate and a manufacturing method thereof, in particular to a power battery cover plate which can achieve a better sealing effect without complicated assembly. Background technique [0002] With the improvement of environmental protection awareness and the advent of the energy revolution, electric vehicles have gradually flourished, which has also driven the market demand for power batteries. Power batteries, with their high capacity and high energy density, have become the power supply for electrical products that require a large amount of power. It is a mainstream technology and is widely used in various products such as electric vehicles and vacuum cleaners. [0003] The existing power battery includes a casing, a cell module and a cover plate, wherein the casing has an opening, the cell module is arranged inside the casing, the cover plate is combined with the casing to close the opening, by With the c...
