Abstract
A method of forming a component can include electrochemically depositing a metallic material onto a carrier component to a thickness of greater than 50 microns. The metallic material can include crystal grains and at least 90% of the crystal grains can include nanotwin boundaries. The metallic material can include at least one of copper or silver.
Claims21
A stock material, comprising:
- a metallic material comprising crystal grains and having a thickness of greater than 50 microns;
- and
- at least 90% of the crystal grains comprising nanotwin boundaries, wherein the crystal grains are equiaxial.
An electronic device, comprising:
- a conductive component comprising a metallic material including crystal grains, the metallic material having a thickness of greater than 50 microns;
- and
- at least 90% of the crystal grains comprising nanotwin boundaries, wherein the crystal grains are equiaxial, the metallic material having a hardness greater than 225 Hv.
A battery, comprising:
- an electrochemical cell comprising an electrolyte, an anode, and a cathode;
- and
- a current collector electrically coupled to one of the anode or the cathode, the current collector comprising a metallic material including crystal grains, at least 90% of the crystal grains comprising nanotwin boundaries, wherein the crystal grains are equiaxial, and wherein the metallic material has a hardness greater than 225 Hv.
