AI Technical Summary
Existing electrochemical battery encapsulation materials are insufficient in terms of tensile strength and aging resistance, making it difficult to meet the requirements of high-energy-density batteries in complex environments. They are prone to problems such as microcracks, delamination, and bulging, which affect the safety and lifespan of the battery.
By using a blend of styrene block copolymer, maleic anhydride-grafted modified styrene-ethylene/butene-styrene, and synergistic resin, and through precise control of component ratios, a high-strength, high-toughness, and high-durability composite encapsulation system is formed, enhancing interlayer adhesion and resistance to environmental aging.
It significantly improves the tensile strength and durability of battery packaging materials, reduces the risk of thermal runaway caused by packaging failure, extends battery life and improves safety, and is suitable for new energy vehicles and energy storage power stations.
