Alternative Current Collectors for Thin Film Batteries and Method for Making the Same

摘要

A thin film battery has one or more current collectors with a substantially mesh configuration. The mesh current collector may include a network or web of thin strands of current collector material. The thin strands may overlap each other and/or may be arranged to define a plurality of individual cells within the mesh current collector. The strands of the mesh current collector may also be arranged to have a grid-like configuration. Additionally, in some configurations, the anode or cathode may fill the cells within the current collector layer to optimize the amount of active material within the battery.
