Lithium ion Pouch Cell Materials Black Aluminum Laminated Film (W200mm*T66um*L25m)

Product features： 1. It is produced by advanced and reliable thermal process The company uses thermal process to produce aluminum-plastic composite eyes. Compared with dry process. The composite between CPP / A1 is bonded without adhesive. It has better electrolyte resistance. Excellent durability and high and low temperature resistance. At the same time, ensure good punching depth and insulation performance. In addition to ordinary civilian areas. It has more obvious application advantages in durability, power vehicle cutting or energy storage lithium battery. 2. Excellent heat sealing strength. It is conducive to battery packaging and processing After many previous experiments. The aluminum-plastic composite film produced by our company has good applicability to all kinds of pole ears. The increase of temperature basically increases the thermal strength. Especially after 180C. The heat sealing strength can be maintained above 75n / 15mm. The temperature is 190-215 ℃, and the heat sealing strength is maintained above 85n / 15m. The temperature is 195 - 215 ℃. More than 90 n / 15mm. The company's aluminum-plastic good can maintain high heat sealing strength in a wide temperature range. 3. Excellent electrolyte resistance Main purpose: It is mainly used in polymer lithium-ion batteries for small electrical appliances such as mobile communications, notebook computers, MP3 players and handheld DVD players, as well as flexible packaging shell packaging materials for ordinary lithium-ion batteries

• Aluminum plastic composite film (hereinafter referred to as "aluminum plastic film") is mainly a composite material composed of on / Al / CPP (outer nylon layer / middle aluminum foil layer / inner heat sealing layer), and the layers are bonded by adhesive. Aluminum plastic film is one of the key materials for flexible packaging lithium battery packaging, which plays a role in protecting the internal cell materials,
• The appearance is smooth and flat without trachoma, fold and other defects;
• Good punching performance, which can meet the requirements of most polymer lithium-ion batteries;
• The inner layer of aluminum-plastic film is high-purity CPP, which has good electrolyte corrosion resistance;
• The product has high barrier, electrolyte stability, good stamping formability and puncture resistance;
