Abstract
Embodiments are disclosed related to a current collector comprising a porous, freestanding, three-dimensional structure and at least one current collector tab. The current collector tab and the three-dimensional structure are connected. The three-dimensional structure comprises at least one layer that is formed of a one-dimensional (1D) nanomaterial, a two-dimensional (2D) nanomaterial, or mixtures thereof, and wherein the nanomaterial in the layer is aligned towards the current collector tab.
Claims15
A current collector comprising:
- a porous, freestanding, three-dimensional structure;
- and
- at least one current collector tab, the at least one tab and the three-dimensional structure being connected,
- wherein the three-dimensional structure comprises at least one layer that is formed of a one-dimensional (1D) nanomaterial, a two-dimensional (2D) nanomaterial, or mixtures thereof, and
- wherein the nanomaterial in said layer is aligned towards the at least one tab.
A method for producing a current collector, the method comprising:
- (a) providing a porous, freestanding, three-dimensional structure comprising at least one layer that is formed of a one-dimensional (1 D) nanomaterial, a two-dimensional (2D) nanomaterial, or mixtures thereof, wherein the nanomaterial is aligned and its-a longitudinal axis thereof is perpendicular to a substrate surface;
- and
- (b) connecting the three-dimensional structure of step (a) to at least one current collector tab so that the nanomaterial comprised in said three-dimensional structure is aligned towards at least one tab.
