Abstract
A silicon and sulfur battery and methods are shown. In one example, the silicon and sulfur battery includes a lithium chip coupled to a silicon electrode. In some examples, the silicon electrode is formed from silicon nanoparticles and carbon.
Claims10
A battery, comprising:
- a first electrode, including:
- a layer of silicon nanoparticles with a bottom surface in contact with a surface of a conductive substrate and a top surface opposite the bottom surface, wherein the layer of silicon nanoparticles includes an access opening to the conductive substrate through the layer of silicon nanoparticles from the top surface to the bottom surface;
- a lithium chip in contact with the layer of silicon nanoparticles at the top surface, and in contact with the surface of the conductive substrate in the access opening, wherein the lithium chip includes a chip bottom surface that is larger than the access opening;
- a second electrode including sulfur;
- and
- an electrolyte in contact with both the first electrode and the second electrode.
