Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] The non-planar polymer lithium battery technology of the present invention comprises the following steps,

[0028] 1) Coat a layer of polyvinylidene fluoride on the upper and lower surfaces of the plane positive and negative electrodes, and the coating amount of polyvinylidene fluoride is 0.1-0.3mg / cm 2 , preferably 0.2mg / cm 2 , Coating a layer of polyvinylidene fluoride on the surface of the pole piece, polyvinylidene fluoride is characterized by making the pole piece plastic within a certain range, so that the pole piece has the characteristics of maintaining a certain shape. At the same time, because the thickness of the polyvinylidene fluoride layer is very small, about 1...

Abstract

The invention discloses a method for manufacturing a non-planar polymer lithium battery. The method comprises the following steps: (1) respectively coating the upper surfaces and the lower surfaces of positive pole pieces and negative pole pieces of a plane with a layer of organic adhesive, wherein the organic adhesive coating amount is 0.1-0.3mg / cm<2>; (2) respectively punching the positive pole pieces and the negative pole pieces to form non-planar pole pieces, wherein the punching temperature is 50-90 DEG C; (3) correspondingly stacking the positive pole pieces and the negative pole pieces, and welding positive pole lugs and the negative pole lugs to obtain a non-planar pole group; (4) coldly pressing the pole group to reduce gaps between the pole pieces and improve stability of the pole group; and (5) putting the pole group into a matched non-planar aluminum plastic packaging bag to hot press and pack to obtain a non-planar polymer lithium battery. Through the method for manufacturing the non-planar polymer lithium battery, the non-planar polymer lithium battery has manufacturability, meets basic electric property, also can ensure stability of the appearance and fills the blank of diverse manufacture of batteries in stereo spaces.

Description

technical field [0001] The invention relates to the technical field of battery preparation, in particular to a method for preparing a non-planar polymer lithium battery. Background technique [0002] At present, with the continuous application and promotion of batteries in various electrical appliances, there are more and more personalized requirements for battery design, and the development of a single model can no longer meet the needs of the market. Therefore, making the battery production "flexible", shortening the sample development cycle, and ensuring the best design and quality have become the key factors to gain customer recognition and occupy the market. Traditional polymer lithium batteries are mostly cuboid or have diverse shapes in two-dimensional space. In today's personalized era, personalized electrical appliances are favored by consumers. Different styles of electrical appliances have great influence on the three-dimensional space shape and electrical perform...
