Abstract
An apparatus includes a first electrode, a second electrode, and a porous layer positioned between the first electrode and the second electrode. The porous layer resists dendrite growth from the first electrode through the porous layer to the second electrode. The porous layer includes a plurality of pores sized to permit ionic transport through the porous layer and to resist dendrite growth through the porous layer.
Claims20
A battery, comprising:
- a first electrode;
- a second electrode;
- and
- a porous layer positioned between the first electrode and the second electrode, wherein the porous layer resists dendrite growth from the first electrode through the porous layer to the second electrode and permits ion transport through the porous layer from the first electrode to the second electrode.
1 more element
A method, comprising:
- assembling a first electrode, a second electrode positioned opposite the first electrode and an electrolyte positioned between the first electrode and the second electrode;
- providing a porous layer between the first electrode and the second electrode and contacting the electrolyte, wherein the porous layer is configured to permit ionic transport from the first electrode to the second electrode through the porous layer, and to resist one or more dendrites attach to the first electrode from extending from a first surface of the porous layer situated opposite the first electrode through the porous layer to a second surface of the proximate layer situated opposite the second electrode.
A device comprising:
- at least one functional component configured to consume electrical power;
- and
- a battery configured to provide electrical power support to the at least one functional component, wherein the battery includes a porous layer situated between a first electrode and a second electrode and configured to permit ionic transport through the porous layer and to resist dendrite growth through the porous layer of one or more dendrites that attach to a first electrode of the battery.
