{"id":294,"count":3,"description":"**Composite copper foil** is a cutting-edge current collector material designed for high-performance lithium-ion batteries. It typically features a sandwich structure, consisting of a lightweight polymer substrate\u2014such as PET or PP\u2014coated on both sides with thin layers of copper. This innovative design significantly enhances battery safety by acting as an internal \"fuse\" to prevent thermal runaway during internal short circuits. Additionally, the polymer core reduces the total weight of the battery, leading to higher energy density and improved vehicle range. By lowering copper consumption, composite copper foil offers a cost-effective and safe solution for the next generation of electric vehicle power systems and large-scale energy storage applications.","link":"https:\/\/oqitop.com\/ko\/metal-composite-materials\/composite-copper-foil\/","name":"Composite Copper Foil","slug":"composite-copper-foil","taxonomy":"products","parent":281,"meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/oqitop.com\/ko\/wp-json\/wp\/v2\/products\/294","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/oqitop.com\/ko\/wp-json\/wp\/v2\/products"}],"about":[{"href":"https:\/\/oqitop.com\/ko\/wp-json\/wp\/v2\/taxonomies\/products"}],"up":[{"embeddable":true,"href":"https:\/\/oqitop.com\/ko\/wp-json\/wp\/v2\/products\/281"}],"wp:post_type":[{"href":"https:\/\/oqitop.com\/ko\/wp-json\/wp\/v2\/product?products=294"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
