Abstract
Methods of forming a battery include forming a thin graphene cathode on a substrate. A lithium anode is formed and an electrolyte is formed between the thin graphene cathode and the lithium anode.
Claims19
A method of forming a battery, comprising:
- forming a thin graphene cathode on a flexible substrate;
- forming a lithium anode;
- and
- forming an electrolyte between the thin graphene cathode and the lithium anode.

A method of forming a battery, comprising:
- forming a cathode on a flexible substrate from a single- or double-layer graphene material;
- forming a lithium anode;
- forming an electrolyte having a high solubility for lithium ions and oxygen between the cathode and the lithium anode, such that lithium ions migrate from the anode through the electrolyte to form Li2O2 at a surface of the cathode;
- and
- positioning a current collector formed from a metal mesh in the electrolyte.
