摘要： When electrode films are prepared for lithium electrochemical cells, problems are often encountered in laminating the films with an appropriate intervening electrolyte layer. This presents a significant challenge because proper alignment of the three layers and complete lamination at the interfaces are crucial to good cell performance. Often lamination is imperfect with gaps and defects at the interfaces. The disclosure herein describes a method of casting or extruding a polymer electrolyte directly onto an electrode film to create an electrode assembly with a continuous, defect-free interface. In some arrangements, there is some slight intermixing of the layers at the interface. A complete cell can be formed by laminating two such electrode assemblies to opposite sides of an additional electrolyte or to one another.
