Abstract
Batteries having improved current collection are provided. In some implementations, an electrode structure of a battery may include an active material and two or more current collectors in electrical communication with the active material. In some implementations, an electrode structure of a battery may include two or more current collector layers. According to various implementations, the electrode structure may or may not include a current collector substrate. In some implementations, a battery anode includes a current collector substrate in electronic contact with nanostructured active material. In order to ensure that electronic communication between the active material and the current collector substrate is maintained throughout the life of the battery, a second electronically conductive path is provided in the form of a current collector layer over the nanostructured active material. The additional layer is thin and electronically conductive, and does not interfere adversely with battery operation.
