Problems solved by technology

The soft-packed battery module combines the soft-packed battery with the frame of the battery through injection molding. The fixed glue that solidifies after injection molding cools and seals and fixes the surroundings of the soft-packed battery. The surroundings of the packaged battery form protection, improve the structural strength of the soft-packed battery, effectively solve the problem that the soft-packed battery is easily damaged during the production and transportation process, and greatly improve the qualified rate of the battery. The cell frame of uniform size is set outside the soft-packed cell, even if the size of the soft-packed cell is unstable, it can ensure that the size of the cell module as a whole is consistent

Embodiment 1

[0029] Such as figure 1 , figure 2 , image 3 As shown, a soft-packed battery module includes a soft-packed battery 1 and a battery frame 2. The battery frame 2 is rectangular, and the battery frame 2 is set around the soft-packed battery 1. The battery frame 2 Cured fixing glue 7 is filled between the inner wall of the inner wall and the soft-packed battery cell 1, and the fixed glue 7 combines the cell frame 2 and the soft-packed battery cell 1 into one. The material of the fixing glue 7 is polyamide. The battery frame 2 is made of ABS plastic. The end of the cell frame 2 is provided with a pair of cell tab slots 5. The position of the cell tab slots 5 corresponds to the position and size of the cell tab 6 on the soft pack cell 1. The cell tab 6 Fastened in the cell lug slot 5. There are binding card slots 3 on both sides of the cell frame 2. The binding card slots 3 are inserted into the outer surfaces of the cell frame 2. The direction of the binding card slot 3 is t...

Embodiment 2

[0038] In step B, the injection temperature is 135°C, and the injection pressure is 1.8kgf / cm2. In step C, the mold is closed for 18 seconds, the mold temperature is controlled at 50°C, and the cycle from mold closing to mold opening is 28 seconds each time. All the other are with embodiment 1.

Embodiment 3

[0040] In step B, the injection temperature is 150°C, and the injection pressure is 1.5kgf / square centimeter. In step C, the mold is closed for 20 seconds, the mold temperature is controlled at 55°C, and the cycle from mold closing to mold opening is 30 seconds each time. All the other are with embodiment 1.

Abstract

The invention discloses a soft package battery cell module. The soft package battery cell module comprises a soft package battery cell and also comprises a battery cell frame, wherein the battery cell frame sleeves the periphery of the soft package battery cell, and a cured fixing adhesive fills between the inner wall of the battery cell frame and the soft package battery cell. The invention also simultaneously discloses a fabrication method of the soft package battery cell module. In the soft package battery cell module, the soft package battery core and the battery core frame having a regular shape are combined to form the soft package battery cell module, the soft package battery cell module has unified size endowed by the battery cell frame, the soft package battery cell can be protected and strengthened by the battery cell frame and the fixing adhesive, so that a usage unit which is easy to assemble, combine, store and transport, has relatively high strength and is practical is obtained, the battery cell damage caused by the production and transportation process of the soft package battery cell is effectively solved, and the qualified rate and the finished rate of the battery cell are greatly improved; and moreover, full-automatic production of a power battery with the soft package battery cell is conveniently achieved, and the production efficiency can be substantially improved.

Description

technical field [0001] The present invention relates to a battery component and its manufacturing method, more specifically, it relates to a soft pack cell module and its manufacturing method. Background technique [0002] The existing lithium-ion battery production technology is becoming more and more mature, and the scale of each manufacturer is also increasing. As a kind of lithium-ion battery, the soft-pack battery pack has gradually shown its advantages in the market due to its light weight, high specific energy, good explosion-proof performance, and strong battery life, but it also encounters some major problems. , restricting the larger-scale application of pouch cell battery packs. Because the packaging material of the soft-packed battery is soft, and for the sake of explosion-proof safety, the packaging material cannot be packaged with too much strength. These factors make the soft-packed battery unable to have sufficient structural rigidity. Therefore, the current...
