Process for forming multilayer articles by melt extrusion |
摘要 |
Multilayer articles, particularly multilayer articles having electrical or ionic conductivity, are made using an improved melt extrusion process. The process includes a combination step in which a macroscopically homogeneous mass is formed prior to introduction into an extruder. The multilayer article may include an electrode layer and a separator layer that are extruded onto a metal current collector. Such structures are particularly useful in lithium-ion batteries.
