摘要： Variable-resistance devices and methods of forming the same include a variable-resistance layer, formed between a first terminal and a second terminal, that varies in resistance based on an oxygen concentration in the variable-resistance layer. An electrolyte layer that is stable at room temperature and that conducts oxygen ions in accordance with an applied voltage is positioned over the variable-resistance layer. A gate layer is configured to apply a voltage on the electrolyte layer and the variable-resistance layer and is positioned over the electrolyte layer.

摘要： A catholyte-like material including a cathode material and an interfacial additive layer for providing a lithium ion energy storage device having low impedance is disclosed. The interfacial additive layer, which is composed of vapor deposited iodine, is present between the cathode material and an electrolyte layer of the device. The presence of such an interfacial additive layer increases the ion and electron mobile dependent performances at the cathode material interface due to significant decrease in the resistance/impedance that is observed at the respective interface as well as the impedance observed in the bulk of the device. The catholyte-like material of the present application can be used to provide a lithium ion energy storage device having high charge/discharge rates and/or high capacity.

摘要： An interfacial additive layer for decreasing the interfacial resistance/impedance of a silicon based electrode-containing device such as, for example, an energy storage device or a micro-resistor, is disclosed. The interfacial additive layer, which is composed of a molten lithium containing salt, is formed between a silicon based electrode and a solid polymer electrolyte layer of the device. The presence of such an interfacial additive layer increases the ion and electron mobile dependent performances at the silicon based electrode interface due to significant decrease in the resistance/impedance that is observed at the respective interface as well as the impedance observed in the bulk of the device.
