{"id":295,"count":2,"description":"**Composite aluminum foil** is an innovative current collector designed primarily for the cathode of high-performance lithium-ion batteries. It features a multi-layered structure consisting of a lightweight polymer core, such as PET or PP, coated with ultra-thin aluminum layers on both sides. This advanced configuration significantly enhances battery safety by reducing the risk of thermal runaway during internal short circuits. Moreover, the lightweight polymer substrate substantially decreases the overall weight of the battery, leading to increased gravimetric energy density. By optimizing material usage and improving mechanical flexibility, composite aluminum foil provides a safe, efficient, and cost-effective solution for electric vehicle power systems and high-capacity energy storage.","link":"https:\/\/oqitop.com\/de\/metal-composite-materials\/composite-aluminum-foil\/","name":"Composite Aluminum Foil","slug":"composite-aluminum-foil","taxonomy":"products","parent":281,"meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/oqitop.com\/de\/wp-json\/wp\/v2\/products\/295","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/oqitop.com\/de\/wp-json\/wp\/v2\/products"}],"about":[{"href":"https:\/\/oqitop.com\/de\/wp-json\/wp\/v2\/taxonomies\/products"}],"up":[{"embeddable":true,"href":"https:\/\/oqitop.com\/de\/wp-json\/wp\/v2\/products\/281"}],"wp:post_type":[{"href":"https:\/\/oqitop.com\/de\/wp-json\/wp\/v2\/product?products=295"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
