Battery labels generally use UV ink or alcohol-based ink.

The following printing and processing methods are common for battery film self-adhesive labels.

(1) The gravure printing method is printed on an ordinary gravure printing machine (generally using a wide-format gravure printing machine), using solvent-based ink.

(2) Gravure back printing method

(3) Letterpress printing method

(4) Flexographic printing method

( 5) Printing coating method

In the structure of lithium batteries, the separator is one of the key inner components. The performance of the separator determines the interface structure, internal resistance, etc. of the battery, which directly affects the capacity, cycle, and safety performance of the battery. Excellent separators play an important role in improving the overall performance of the battery. The main function of the separator is to separate the positive and negative electrodes of the battery to prevent the two electrodes from contacting and causing a short circuit. In addition, it also has the function of allowing electrolyte ions to pass through. The separator material is non-conductive, and its physical and chemical properties have a great impact on the performance of the battery.
