description A dual-layer gradient electrode structure is provided for optimizing power and energy density in batteries. In use, for an electrode of a lithium-based battery, the electrode includes a first layer above an electrically conductive substrate, the first layer including a first plurality of carbon aggregates having a first porosity. Additionally, a second layer is above, at least in part, the first layer, the second layer having a second porosity, and including a second plurality of carbon aggregates. The second plurality of carbon aggregates includes a first group of aggregates and a second group of aggregates. The first group of aggregates is characterized by a first porous structure, and the second group of aggregates is characterized by a second porous structure. Further, the second porous structure is characterized by a density greater than the first porous structure, and the second porosity is greater than the first porosity.
