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.
Claims17
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.
1 more element
An apparatus, comprising:
- a first graphene oxide-based material having a first functionality of a first concentration;
- a second material having a second functionality of a second concentration;
- a junction defined by an interface of the first graphene oxide-based material positioned adjacent and in contact with the second material;
- and
- electrodes formed on each of the first graphene oxide-based material and the second material;
- wherein protons are configured to be dissociated from the first functionality of the first graphene oxide-based material by water and are configured to be migratable across the junction to the second material based on a pH gradient across the first graphene oxide-based material and the second material.
3 more elements
A method, comprising:
- dissociating hydrogen from functional groups of a first graphene oxide-based material to form protons;
- causing the protons to diffuse from the first graphene oxide-based material across a junction to a second material;
- and
- determining a value representing a voltage based on the diffusion of the protons to the second material.
