Abstract
In some embodiments, an electrode can include a first and second conductive layer. At least one of the first and second conductive layers can include porosity configured to allow electrolyte to flow therethrough. The electrode can also include an electrochemically active layer having electrochemically active material sandwiched between the first and second conductive layers. The electrochemically active layer can be in electrical communication with the first and second conductive layers.
