Zusammenfassung:	Methods are disclosed for manufacturing an electrode for use in a device such as a secondary battery. Electrodes may include a first layer having first active particles adhered together by a binder, a second layer having second active particles adhered together by a binder, and an interphase layer interposed between the first and second layers. In some examples, the interphase layer may include an interpenetration of the first and second particles, such that substantially discrete fingers of the first layer interlock with substantially discrete fingers of the second layer.
