Remember how in the old battery, the different components were all layered? In the 3D battery the cathode and anode are intertwined using copper foam substrate or nanowire, making for a greater amount of surface area for the ions to travel. The result is, “Very high power density, faster charger, more energy, and a much longer battery life,”  Citrus Based 3D Battery Architecture puts the Energizer Bunny to Shame
