In a typical experiment, a graphite rod (Alfa Aesar with 99.999%
purity, 6 mm in diameter and 50 mm long) was used as the anode and
another graphite rod (13 mm in diameter and 60 mm in length) was used
as the cathode. The discharge current was in the 100-150 A range, with a
maximum open circuit voltage of 60 V [40]. In Fig. 5 we show typical
TEM and AFM images of the sample. An important aspect of the
