The battery label body includes a printing ink layer 1, a PI substrate layer 2, and an acrylic glue layer 3. The printing ink layer 1 includes a character printing layer 101, a black ink layer 102, and a gray ink layer 103 arranged in sequence from top to bottom. The acrylic glue layer 3, the PI substrate layer 2, the gray ink layer 103, the black ink layer 102, and the character printing layer 101 are stacked in sequence from bottom to top;

[0021] The acrylic glue layer 3 is adhesively fixed to the bottom of the PI substrate layer 2; the gray ink layer 103 is arranged on the top of the PI substrate layer 2 by printing and coating, the black ink layer 102 is arranged on the top of the gray ink layer 103 by printing and coating, the character printing layer 101 is extremely fine characters arranged on the top of the black ink layer 102 by printing, the character line width is 0.06 mm, and the characters have no appearance defects such as broken lines, smeared characters, and plugged holes; among them, by printing extremely fine characters, the battery label body can be applied to the batteries of different electronic products, such as smaller Bluetooth headset batteries, etc.; among them, the black ink layer 102 can adapt to a variety of different types of printing inks and can meet different process requirements; among them, the PI substrate layer 2 is used to make the battery label body have fire and heat resistance performance;

[0022] The gray ink layer 103 is the display layer for the traceable two-dimensional code. By laser engraving the traceable two-dimensional code at the center of the black ink layer 102 and removing the black ink part through laser engraving, the gray ink layer 103 is exposed as the display layer, achieving the effect that the color of the laser-engraved two-dimensional code is the same as the color of the surface-printed text. Among them, different colors of ink can also be printed and coated on the gray ink layer 103 to achieve different colors of two-dimensional code effects. The laser-engraved traceable two-dimensional code is a variable two-dimensional code, and the encoded content can be determined according to customer requirements. The barcode level of the two-dimensional code reaches above level C.

[0023] The acrylic glue layer 3 is a double-sided adhesive used to bond the battery label body and the client cell core. The acrylic glue layer 3 can be changed differently according to the requirements of the back sticker and the overall unit assembly effect. For example, parameters such as the peel strength can use different peel strength acrylic glue layers 3 according to different back stickers to achieve the effect that the label adheres to different batteries without delaminating or warping.

[0024] The usage method of this embodiment is as follows: By using extremely fine text with a printed text line width of 0.06 mm in the topmost black ink layer 102 as the text printing layer 101, and then through laser engraving, the traceable two-dimensional code is laser engraved at the center of the battery label body. The black ink part is removed by laser engraving, and the gray ink layer 103 is exposed, achieving the effect that the color of the laser-engraved two-dimensional code is the same as the color of the surface-printed text. This process design overcomes the printing problems such as easy wire breakage, smeared characters, and plugged holes in screen printing of letters with a 0.06 mm line width. At the same time, it realizes the combination of the printing process and the laser engraving process, solves the problem of unclear printing and difficult scanning of small-size traceable two-dimensional codes, greatly reduces the defect rate of printing extremely fine text labels and traceable two-dimensional codes on battery small labels, and avoids the risk of a large amount of scrapping and rework after the battery pack is assembled.
