Abstract
An apparatus comprises an anode formed of graphene oxide from an acidic pH; a cathode from a pH greater than the acidic pH of the anode; and charge collectors deposited on the anode and the cathode. The anode comprises graphene oxide, the graphene oxide comprising an ink and having a pH of about 1 to about 4.
Claims5
An apparatus, comprising:
- an anode formed of graphene oxide from an acidic pH;
- a cathode from a pH greater than the acidic pH of the anode;
- and
- charge collectors deposited on the anode and the cathode;
- wherein the anode comprises graphene oxide, the graphene oxide comprising an ink and having a pH of about 1 to about 4;
- wherein a difference between the acidic pH of the graphene oxide and a higher pH dissociates protons coupled to the graphene oxide to cause the protons to migrate from the graphene oxide of the anode to the cathode to regenerate the apparatus;
- wherein the cathode is formed of graphene oxide from inks and has a pH of about 13 to about 14.
