Abstract
A lithium-sulfide-carbon composite and methods are shown. In one example, the lithium-sulfide-carbon composites are used as an electrode in a battery, such as a lithium ion battery.
Claims18
A method of forming a battery electrode, comprising:
- forming a precursor solution including a lithium sulfide precursor and a carbon precursor;
- converting the precursor solution into an aerosol;
- removing water from the aerosol to form precursor particles;
- reacting the precursor particles at a first reaction temperature to form a lithium carbonate-carbon composite;
- and
- reacting the lithium carbonate-carbon composite with hydrogen sulfide to form a lithium-sulfide-carbon composite.
3 more elements
An electrode, comprising:
- a plurality of lithium sulfide composite particles, wherein individual lithium sulfide composite particles include;
- a carbon matrix;
- and
- a plurality of lithium-sulfide particles uniformly distributed into the carbon matrix, wherein multiple lithium sulfide particles are contained within a continuous carbon matrix.
1 more element
A battery, comprising:
- a first electrode, including:
- a plurality of lithium sulfide composite particles, wherein individual lithium sulfide composite particles include a plurality of lithium-sulfide particles in a carbon matrix, wherein multiple lithium sulfide particles are contained within a continuous carbon matrix;
- a second electrode;
- and
- an electrolyte in contact with both the first electrode and the second electrode.
