[0074] Currently, judging from market trends, the application of power batteries is becoming increasingly widespread. Power batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also extensively used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of power battery applications, market demand is also constantly increasing.

[0075] Energy conservation and emission reduction are key to the sustainable development of the automotive industry, and electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important component of this sustainable development. For electric vehicles, battery technology is a crucial factor in their development. The battery manufacturing process includes the addition of powder materials, and reducing the cost of this process is a pressing issue that needs to be addressed.

[0076] The inventors have noted that in the process of adding raw materials during battery manufacturing, the raw material packaging device accounts for a considerable portion of the cost.

[0077] In order to improve this situation, the applicant, through disassembly and research on the unpacking and packaging devices in the prior art, found that the packaging device containing raw materials includes a cutting device that cuts open the inner packaging bag and the outer packaging bag after the packaging device enters the unpacking device, so that the contents flow out from the packaging bag.

[0078] Based on the problems discovered by the inventors, the inventors improved the packaging bag. The packaging bag includes a body and a connector. The body includes a chamber for containing filler, which is surrounded by a bottom wall and side walls. A slit extending in a second direction is provided through the bottom wall so that the filler can flow out from the slit. The connector can be detachably covered on the slit. After the filler flows out from the slit, the connector can be re-covered on the slit to realize the recycling of the packaging bag and reduce the cost of the packaging bag and the raw material filling process.

[0079] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a packaging bag 21 provided in an embodiment of this application.

The first direction X and the second direction Y intersect. The connector 212 is detachably covered on the slit 2114.

[0081] The main body 211 includes a cavity 2113 enclosed by a bottom wall 2111 and side walls 2112, which is used to contain filler. A slit 2114 is provided on the bottom wall 2111 of the main body 211, and a connector 212 is detachably covered by the slit 2114. When the connector 212 separates from the main body 211, exposing the slit 2114, the filler in the cavity 2113 flows out through the slit 2114; when some of the filler flows out through the slit 2114, the connector 212 is re-covered at the slit 2114 to achieve recycling of the packaging bag 21.
