Problems solved by technology

[0002] At present, in the existing forming technology of soft pack lithium-ion battery packaging film, mechanical concave-convex molds are usually used to stamp and form the soft pack material used for lithium-ion batteries, which may easily lead to uneven forming of the packaging film, and the packaging material after stamping becomes deformed. Thin is more serious
In addition, the structure of this traditional concave-convex mold is relatively complicated

Abstract

The invention provides an air pressure forming die and an air pressure forming method for lithium-ion battery packaging film to overcome the problem of uneven forming caused by stamping and forming soft package materials used in lithium-ion batteries by using existing concave-convex molds . The air pressure forming mold includes a die, a support plate and a sealing strip, wherein the support plate is provided with a vent hole penetrating from one plate surface to the other plate surface, and the sealing strip is fixed or detachable on the cavity of the die or the support plate. On the surface, to make the contact between the die and the support plate sealed when the die is in contact with the support plate. The air pressure forming method uses the above air pressure forming die to perform air pressure forming on the aluminum-plastic composite film. The air pressure forming die and air pressure forming method of the present invention can make the stamping and forming more uniform, and can be applied to the field of soft-pack lithium-ion battery production.

Description

technical field [0001] The invention relates to the field of soft-pack lithium-ion battery production, in particular to an air-pressure forming die and an air-pressure forming method for lithium-ion battery packaging films. Background technique [0002] At present, in the existing forming technology of soft pack lithium-ion battery packaging film, mechanical concave-convex molds are usually used to stamp and form the soft pack material used for lithium-ion batteries, which may easily lead to uneven forming of the packaging film, and the packaging material after stamping becomes deformed. Thin is more serious. In addition, the structure of this traditional concave-convex mold is relatively complicated. Contents of the invention [0003] A brief overview of the invention is given below in order to provide a basic understanding of some aspects of the invention. It should be understood that this summary is not an exhaustive overview of the invention. It is not intended to i...
