Lateral dimensions for the devices may also take on any suitable value, and may (at least) linearly contribute to the amount of energy stored by the devices. For example, in some embodiments, the lateral dimensions of the electrodes and the solid electrolyte may be as small as or about 20 nm or less, and may be limited by the deposition abilities used during fabrication. Various masking and lithographic processes may be used, for example, to achieve lateral dimensions as small as or about 10 nm. In other embodiments, the lateral dimensions may take on larger values, such as greater than or about 1 μm, greater than or about 10 μm, greater than or about 100 μm, greater than or about 1 mm, greater than or about 1 cm, or greater than or about 10 cm. Again, the maximum lateral dimensions achievable may be limited by the deposition abilities used, but are virtually without limit.
One advantage of such miniaturized energy storage devices is that multiple individual devices may be attached to one another to form an energy distribution network. Energy distribution networks of this nature may be useful for providing power at the point of load, minimizing power transmission distances and associated resistive losses and heat generation. Energy distribution networks may also be useful for sequestering attached devices from fluctuating electrical loads engendered by other components. For example, when included in an integrated circuit, such as in combination with inductive coupling, an energy distribution network may protect circuits from electrical fluctuations generated by circuit blocks elsewhere on the wafer.
