[0098] In some embodiments, the assembly production system 320 and the electrode tab production system 310 can be located in two production spaces respectively. After the electrode tab production system 310 produces the electrode tab, the electrode tab can be sealed and transported to the assembly production system 320 to produce the battery.

[0099] In some other embodiments, the battery production line can include two electrode sheet production systems 310 and at least one assembly production system 320, the electrode sheets produced by the two electrode sheet production systems 310 can be simultaneously input into the assembly production system 320, so as to improve the production efficiency of the battery.

[0100] In the present embodiment, the battery production line further includes a conveyor belt. The conveyor belt is used to connect two adjacent devices in the battery production line, so as to effectively improve the transportation efficiency of the materials and the production efficiency of the battery.

[0101] Referring to Figures 1 to 3 Figures 1 to 3 Figures 1 to 3 Figures 1 to 3 The present application provides a container-type battery production system. When a battery production system needs to be built, a plurality of containers 100 and devices in the containers 100 are transported to the destination.

[0102] The plurality of containers 100 are laid flat or stacked in sequence, and any two adjacent containers 100 are connected by a sealed passage, so that the dust-free spaces 140 in the plurality of containers 100 are connected to form a production space. After the plurality of containers 100 are connected, fasteners are used to fasten the connection, so as to improve the connection strength and reliability of the plurality of containers 100 and the sealed passage.

[0103] When the plurality of dust-free spaces 140 are connected to form a production space, the devices in the dust-free spaces 140 are combined in sequence to form an electrode sheet production system 310 and an assembly production system 320. The electrode sheet production system 310 can produce raw materials into electrode sheets. The assembly production system 320 can assemble the electrode sheets, the shell, the electrolyte and other components to form a new energy battery.

[0104] The battery production line is contained in the container 100, which can effectively reduce the environmental requirements of the battery production line, so that the battery production system can be suitable for various environments, improve the construction efficiency of the battery production system, and reduce the construction cost of the battery production system. Moreover, the container-type battery production system is also convenient for the assembly, improvement, maintenance and upgrading of the battery production line.

[0105] Although the present application has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary, rather than limiting. Since the present application can be embodied in many different forms without departing from the spirit or essential characteristics thereof, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but rather are to be broadly interpreted within the spirit and scope of the appended claims, and all changes and modifications that fall within the metes and bounds of the claims, or equivalents of such metes and bounds, are intended to be embraced by the claims.
