Energy storage in arrays of
nano junctions:
design prevents tunneling and electrical
breakdown;
each element can be individually
charged/discharged, as in a flash drive;
can be part of integrated circuits, CPUs, sensors;
high energy density > 1 GJ/m3 (200 kJ/kg), high power density;
charging-discharging rates in the THz range, and exceed number of charging cycles of chemical batteries and conventional capacitors by orders of magnitude;
fully operational in a large temperature range (from absolute zero to electrode melting temperature) and no thermal run-away;
high capacitance, small leak currents (theoretical decay time: thousands of years).
open problem: experimental verification of energy density for nano gaps
Digital batteries are similar to flash drives: flash drives store charge, while digital batteries store energy
