Abstract
A component for a lithium battery including a first layer including a lithium garnet having a porosity of 0 percent to less than 25 percent, based on a total volume of the first layer; and a second layer on the first layer and having a porosity of 25 percent to 80 percent, based on a total volume of the second layer, wherein the second layer is on the first layer and the second layer has a composition that is different from a composition of the first layer.
Claims19
A component for a lithium battery comprising:
- a first layer comprising a lithium garnet having a porosity of 0 percent to less than 25 percent, based on a total volume of the first layer;
- and
- a second layer on the first layer and having a porosity of 25 percent to 80 percent, based on a total volume of the second layer,
- wherein the second layer is on the first layer and the second layer has a composition that is different from a composition of the first layer;
- and
- wherein an average pore diameter in the second layer is 1 nanometer to 50 nanometers.
