METALLIZED FIBERS FOR ELECTROCHEMICAL ENERGY STORAGE

摘要

A cost effective method and apparatus are provided for forming metallized fibers and depositing multilayer films thereon to form thin film electrochemical energy storage devices. In one embodiment, a fibrous substrate is formed using a fiber spinning process and the fibrous substrate is plated with a copper layer using wet deposition. Multiple material layers are then deposited onto the copper layer to form a lithium-ion battery fiber.
