Scope

Scope: This document specifies the abbreviations, classification, structure, requirements, inspection rules, marking, packaging, transportation, and storage of aluminum-plastic encapsulation films (hereinafter referred to as aluminum-plastic films) for lithium-ion batteries, and describes the corresponding test methods. This document applies to the following composite structure aluminum-plastic encapsulation films, which consist of a core aluminum foil layer, an inner side composite heat-sealing layer, and an outer side composite protective layer. These film materials are used for the production, inspection, and sales of multi-layer composite aluminum-plastic films for lithium-ion battery encapsulation. Main technical contents: 6.1 Appearance: The appearance of the aluminum-plastic film shall comply with the provisions of Table 1. 6.2 Dimensions and deviations: The dimensions and deviations shall comply with the provisions of Table 2. 6.3 Performance requirements: The performance requirements shall comply with the provisions of Table 3. 6.4 Restricted substances: They shall comply with the provisions of GB/T 26572. 7. Test methods 7.1 Standard environment for sample conditioning and testing: In accordance with the provisions of GB/T 2918, the temperature shall be (23±2)℃, and the relative humidity shall be (50±10)%. The conditioning time shall be no less than 24 hours, and the test shall be conducted under these conditions. 7.2 Appearance: Visually inspect under natural light. Measure the flatness of the end face using a gauge with a graduation value of no more than 0.5mm. 7.3 Dimensions and deviations: Determine the width and deviations in accordance with the provisions of GB/T 6673, and determine the thickness and deviations in accordance with the provisions of GB/T 6672. Determine the length and deviations using an automatic meter. 7.4 Peel strength: Conduct the test in accordance with the provisions of GB/T 8808. Use a long strip with a length of ≥200mm and a
