Abstract
Official abstract text for this publication.
Approaches herein provide a device, such as a battery protection device, including a cathode current collector and an anode current collector provided atop a substrate, a cathode provided atop the cathode current collector, and an electrolyte layer provided over the cathode. An interlayer, such as one or more layers of silicon, antimony, magnesium, titanium, magnesium lithium, and/or silver lithium, is formed over the electrolyte layer. An anode contact layer, such as an anode or anode current collector, is then provided over the interlayer. By providing the interlayer atop the electrolyte layer prior to anode contact layer deposition, lithium from the cathode side alloys with the interlayer, thus providing a more isotropic or uniaxial detachment of the anode contact layer.
First claim
Opening claim text (preview).
What is claimed is: 1. A thin film device comprising: a cathode current collector and a first anode current collector formed atop a substrate; a cathode formed atop the cathode current collector; an electrolyte layer formed over the cathode, wherein the electrolyte layer is provided directly atop the cathode current collector and directly atop the first anode current collector; an interlayer formed over the electrolyte layer and directly atop a portion of the first anode current collector; and at least one of: an anode disposed over the interlayer, and a second anode current collector disposed over the interlayer. 2. The thin film device of claim 1 , wherein the anode is an electrochemically active layer. 3. The thin film device of claim 1 , further comprising one or more additional interlayers formed over the electrolyte layer. 4. The thin film device of claim 1 , further comprising an encapsulation layer formed the anode or the second anode current collector. 5. The thin film device of claim 1 , wherein the interlayer is at least one of: silicon, antimony, magnesium, titanium, magnesium lithium, and silver lithium. 6. The thin film device of claim 1 , wherein the interlayer is provided directly atop the electrolyte layer. 7. A method of forming a device comprising: providing a cathode current collector and a first anode current collector atop a substrate; providing a cathode atop the cathode current collector; forming an electrolyte layer over the cathode and directly atop a portion of the cathode current collector and directly atop a portion of the first anode current collector; forming an interlayer over the electrolyte layer; and forming an anode contact layer atop the interlayer. 8. The method of claim 7 , the anode contact layer comprising at least one of: an anode, and a second anode current collector. 9. The method of claim 7 , further comprising forming an encapsulation layer over the anode contact layer. 10. The method of claim 7 , wherein the interlayer is at least one of: silicon, antimony, magnesium, titanium, magnesium lithium, and silver lithium.
