1. A conductive ink comprising:
(a) graphene sheets, wherein:
(i) at least about 90% of the graphene sheets consist of a single layer;
(ii) the graphene sheets have an oxygen content of at most about 6%; or
(iii) both;
(b) a binder;
(c) a stabilizer, the stabilizer comprises polytetrahydrofuran and diethylene glycol, wherein a ratio between the polytetrahydrofuran and the diethylene glycol is about 8:1 to about 11:1; and
(d) a solvent.
