Abstract
A nanoparticle and a method for fabricating the nanoparticle utilize a decomposable material yoke located within permeable organic polymer material shell and separated from the permeable organic polymer material shell by a void space. When the decomposable material yoke comprises a sulfur material and the permeable organic polymer material shell comprises a material permeable to both a sulfur material vapor and a lithium ion within a battery electrolyte the nanoparticle may be used within an electrode for a Li/S battery absent the negative effects of battery electrode materials expansion.
Claims45
A nanoparticle comprising:
- a yoke comprising a sulfur material;
- and
- a single shell comprising a permeable, sulfur-functionalized organic polymer material shell and surrounding the yoke, wherein the polymer is cross-linked by sulfide, disulfide, or a combination thereof.
An electrode comprising:
- a conductive substrate;
- and
- a coating located upon the conductive substrate, the coating consisting of a yoke, a single shell, and a void space interposed between the yoke and the shell, wherein the shell comprises a permeable organic polymer material and surrounds the yolk, and wherein the polymer is cross-linked by sulfide, disulfide, or a combination thereof.
A battery comprising an electrode comprising:
- a conductive substrate;
- and
- a coating located upon the conductive substrate, the coating including a nanoparticle consisting of a yoke and a single shell, wherein the shell comprises a sulfur-functionalized, permeable organic polymer material and surrounds the yolk, and wherein the polymer is cross-linked by sulfide, disulfide, or a combination thereof.
A nanoparticle comprising:
- a yolk comprising a sulfur material;
- and
- a shell comprising a permeable organic polymer material surrounding the yolk, wherein the yolk is contacting the polymer material, wherein the polymer is cross-linked by sulfide, disulfide, or a combination thereof.
A nanoparticle comprising:
- a yolk comprising a sulfur material;
- a shell comprising a permeable organic polymer material surrounding the yolk, wherein the polymer is cross-linked by sulfide, disulfide, or a combination thereof;
- and
- a void space interposed between the yolk and the shell, wherein the void space is adjacent to the permeable organic polymer material.
