Abstract

The invention disclosed a packaging method for cylinder-type lithium-ion battery, which is implemented by the following steps: first using aluminum-plastic packaging bags as battery casing material, using punch shell mold to make two same columnar semicircle out of the central flank, then folding them to be cylinder, finally loading the battery group into the above shell, and completing battery package through double edge closure, injecting fluid, air bleed, single edge closure, and chemical synthesis. The invention saves roller shafts sealing and laser welding processes, and the corresponding equipment.

Description

The method for packing of cylindrical lithium ion battery
Technical field
The present invention relates to electric power storage goods field, more particularly, relate to a kind of method for packing of cylindrical lithium ion battery.
Background technology
Cylindrical lithium ion battery generally uses the nickel plating box hat as battery case at present, and the cost of raw material is higher; Need to encapsulate through operations such as slot rolling, Laser Welding, machinery seal, course of processing complexity, manufacturing cost is higher; The block that needs special shape is as the safety anti-explosive measure; In addition, steel shell has increased the weight of battery, has reduced the gravimetric specific energy of lithium ion battery.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiencies in the prior art, and a kind of method for packing of cylindrical lithium ion battery is provided.
The method for packing of cylindrical lithium ion battery of the present invention, be achieved by following technical proposals, finish by following step: at first use plastic-aluminum encapsulation bag as property material for battery shell, with 2 equal semicircle column types being gone out at middle part, plastic-aluminum encapsulation bag one side towards the shell mould, after 2 the semicircle column types doubling that will go out then column type, at last the battery utmost point is assembled into the plastic-aluminum envelope housing after the above-mentioned punching press, finishes cell package through two edge sealing, fluid injection, exhaust, monolateral envelope, formation process.
The present invention adopts the shell of plastic-aluminum encapsulation bag as cylindrical lithium ion battery, and it is low to have the cost of raw material, gravimetric specific energy height, advantage such as processing technology is simple, and security performance is good.In manufacture process, saved slot rolling and sealed and operations such as laser welding, and the employed relevant device of these operations.
Description of drawings
Fig. 1 is that cylindrical lithium ion battery of the present invention is towards shell schematic diagram vertical view;
Fig. 2 is the end view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
At first use plastic-aluminum encapsulation bag as property material for battery shell, as shown in Figure 1, with 2 equal semicircle column types 1 and 2 being gone out at middle part, plastic-aluminum encapsulation bag one side towards the shell mould, after 2 the semicircle column types doubling that will go out then column type (as shown in Figure 2, with semicircle column type 1 and 2 doublings), at last the battery utmost point is assembled into the plastic-aluminum envelope housing after the above-mentioned punching press, finishes cell package through two edge sealing, fluid injection, exhaust, monolateral envelope, formation process.
The present invention adopts the shell of plastic-aluminum encapsulation bag as cylindrical lithium ion battery, and in manufacture process, saved slot rolling and sealed and operation such as laser welding, and the employed relevant device of these operations.
