Apparatuses, systems, and methods of storing electrical energy for electric vehicles are provided. A battery pack can be disposed in an electric vehicle to power the electric vehicle. A battery cell can be arranged in the battery pack. The battery cell can include a housing. The housing can define a cavity within the housing. The cavity of the battery cell can include a separator having a first side and a second side, a cathode disposed along the first side of the separator, and an anode disposed along the second side of the separator. The anode can include a first portion adjacent to the second side of the separator, and a second portion adjacent to the first portion and separated from the separator by the first portion. A porosity of the first portion of the anode can be greater than a porosity of the second portion of the anode.
