Embodiment Construction

[0018] In order to facilitate the understanding of those skilled in the art, the present invention will be further described in detail below with reference to the drawings and embodiments. details as follows:

[0019] As shown in the figure, the battery pack structure includes the battery cell 1 and the protective plate 2. An aluminum-plastic film 9 for encapsulating the battery cell 1 is provided outside the battery cell 1. The aluminum-plastic film 9 includes two pieces arranged opposite to each other up and down. The edges of the aluminum-plastic film 9 are sealed and connected, and the cell 1 is packaged in two pieces of aluminum-plastic film 9, and a 45° folding angle 10 is provided around the two pieces of aluminum-plastic film 9, and the 45° folding angle 10 passes through the two pieces of aluminum-plastic film The corners of 9 are folded inward by 180°. A plastic protective cover 8 for wrapping the aluminum-plastic film 9 is provided on the outside of the aluminum-pla...

Abstract

The invention discloses a battery pack structure which comprises a battery cell (1) and a protective plate (2), wherein two aluminum plastic films (9) for packaging the battery cell are arranged outside the battery cell, the aluminum plastic films are oppositely arranged up and down, the edges of the two aluminum plastic films are hermetically connected, the battery cell is packaged in the two aluminum plastic films, 45-degree folding angles (10) are arranged on the peripheries of the two aluminum plastic films, the 45-degree folding angles are formed by inwards folding the corners of the two aluminum plastic films by 180 degrees, a plastic protective sleeve (8) used for wrapping the aluminum plastic film is arranged on the outer surface of the aluminum plastic film, and a positive pole lug (3) and a negative pole lug (4) are arranged on the battery cell. According to the invention, the 45-degree folding angles are arranged on the peripheries of the two aluminum plastic films, the 45-degree folding angles are formed by inwards folding the corners of the two aluminum plastic films by 180 degrees, and the plastic protective sleeves for wrapping the aluminum plastic films are arranged on the outer surfaces of the aluminum plastic films, so that the problems of unsealing and electric leakage of battery cell packaging can be well solved.

Description

technical field [0001] The invention relates to the field of battery pack structures, in particular to a battery pack structure. Background technique [0002] In the manufacturing process of the micro-battery pack structure, it is often necessary to package the battery cells. However, the existing battery packs are unsealed, and the existing battery cells may leak electricity when they encounter moisture or rain. Contents of the invention [0003] The invention provides a battery pack structure, which solves the problems of unsealing and leakage of electric core packaging in the prior art. [0004] In order to solve the above technical problems, the technical solution of the present invention is: a battery pack structure, including a battery cell and a protective plate, and an aluminum-plastic film for encapsulating the battery cell is arranged outside the battery cell, and the aluminum-plastic film It includes two pieces that are set up and down opposite to each other. T...
