▎ 摘　　要

NOVELTY - The electrode (20) has a planar electrode body provided with hexagonally shaped through-holes formed in the planar electrode body. An outer layer of graphene covers a portion (34) of the planar electrode body, where the outer layer of graphene is formed by apply graphene platelets to the portion of the planar electrode body, anneals the graphene platelets to form the outer layer of graphene, covers the portion of the planar electrode body, and annealed by a laser after being applied to the portion of the planar electrode body. USE - Grid electrode for a polar solvent-based hydro-pyroelectrodynamic electrical energy storage device. ADVANTAGE - The electrode utilizes a compression that maintains the portion of an electrical conductor inside a recess and helps keep the portion of the electrical conductor separated from solution. The electrode does not require structures to provide a good electrical contact between the electrode and the electrical conductor. DETAILED DESCRIPTION - The planar electrode body is constructed using three-dimensional printing, and constructed from an aliphatic hydrocarbon-based polymer filament. An INDEPENDENT CLAIM is also included for a method for constructing an electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of an electrode.
