Abstract
Three-dimensional micro-supercapacitors and methods for fabrication of micro-supercapacitors are provided. A micro-supercapacitor embodiment includes a three-dimensional electrode with self-supporting layers of two-dimensional nanomaterial. A method embodiment includes using non-contact 3D printing to generate a micro-supercapacitor, including a three-dimensional electrode having self-supporting two-dimensional nanomaterial.
Claims26
A micro-supercapacitor comprising:
- a three-dimensional electrode having
- (i) a plurality of self-supporting layers of two-dimensional nanomaterial stacked in a vertical direction, the plurality of self-supporting layers defining one or more shapes in a plane that is at an arbitrary angle to the vertical direction, and
- (ii) a height in the vertical direction that is at least 10 times greater than the minimum feature size of the one or more shapes, wherein the minimum feature size of the one or more shapes in a plane perpendicular to the vertical direction is between 2 and 50 micrometers.
A micro-supercapacitor comprising:
- a three-dimensional electrode having
- (i) a plurality of self-supporting layers of two-dimensional nanoparticle material stacked in a vertical direction, the plurality of self-supporting layers defining one or more shapes in a plane that is at an arbitrary angle to the vertical direction, and
- (ii) a height in the vertical direction that is at least 10 times greater than a minimum feature size of the one or more shapes, wherein the minimum feature size of the one or more shapes in a plane perpendicular to the vertical direction is between 2 and 50 micrometers, and wherein the self-supporting layers define overhang features without support structures.
A method of forming a micro-supercapacitor comprising:
- using non-contact 3D printing to generate a micro-supercapacitor including a three-dimensional electrode having (i) a plurality of self-supporting layers of two-dimensional nanomaterial stacked in a vertical direction, the plurality of self-supporting layers defining one or more shapes in a plane that is at an arbitrary angle to the vertical direction, and (ii) a height in the vertical direction that is at least 10 times greater than a minimum feature size of the one or more shapes, wherein the minimum feature size of the one or more shapes in a plane perpendicular to the vertical direction is between 2 and 50 micrometers.
