Wet-on-wet application to produce composites suitable for use in lithium-ion batteries

摘要

The invention relates to a process for production of a composite article comprising: A) at least one substrate film A and, applied thereto, B) at least one separator layer B which comprises from 1 to 95% by weight of a solid and comprises no electron-conducting, electrochemically active compound, and C) at least one negative-electrode layer C or D) at least one positive-electrode layer D, or at least one negative-electrode layer C and at least one positive electrode layer D, wherein the at least one separator layer B and the at least one negative-electrode layer C or the at least one positive-electrode layer D or the at least one negative-electrode layer C and the at least one positive-electrode layer D are brought into contact with one another by a wet-on-wet coating process.
