In some embodiments, the apparatus includes a support, a first conductive layer deposited on a first surface area of the support, a thin-film battery including a cathode layer, a solid-state electrolyte layer, and an anode layer deposited such that either the anode layer or the cathode layer is in electrical contact with the first conductive layer, an antenna mounted to the support structure, and an electronic communications circuit mounted to the support and electrically coupled to the battery and the antenna to transceive radio communications. Other embodiments include an energy-receiving device mounted to the support structure, and an electronic communications circuit mounted to the support structure and including a recharging circuit, the recharging circuit electrically coupled to the battery and the energy-receiving device to recharge the battery using energy received by the energy-receiving device. | 12-08-2011 |
| 20110097609 | METHOD AND APPARATUS FOR INTEGRATED-CIRCUIT BATTERY DEVICES - A combined battery and device apparatus and associated method. This apparatus includes a first conductive layer, a battery comprising a cathode layer; an anode layer, and an electrolyte layer located between and electrically isolating the anode layer from the cathode layer, wherein the anode or the cathode or both include an intercalation material, the battery disposed such that either the cathode layer or the anode layer is in electrical contact with the first conductive layer, and an electrical circuit adjacent face-to-face to and electrically connected to the battery. Some embodiments further include a photovoltaic cell and/or thin-film capacitor. In some embodiments, the substrate includes a polymer having a melting point substantially below 700 degrees centigrade. In some embodiments, the substrate includes a glass. For example, some embodiments include a battery deposited directly on the back of a liquid-crystal display (LCD) device. | 04-28-2011 |
| 20100104942 | SUBSTRATE FOR LITHIUM THIN FILM BATTERY - When attempting to make a lithium ion-switching device such as a high-efficiency, all-solid state, thin film battery the choice of carrier substrate is all important. As such a substrate must withstand a high temperature under an oxidising atmosphere to crystallise certain layers making up the device, the substrate should not oxidise thereby ruling out most metals. The invention now describes a class of ternary alloys of which the oxidation rate is limited and that are useable to produce thin film batteries on. At least one element with a high affinity to oxygen (Al, Mg, Zn or Si) is present in the alloy. The other two metallic elements reduce the growth of the oxide of this first element. In addition the thus formed oxide scale turns out to be an effective barrier to lithium. Surprisingly, the scale shows nanoscopic voids that allow for sufficient electrical contact with the device layers, thereby eliminating the need for a separate current collector. As the ternary alloy can be made in a flexible foil, it can advantageously be used in a roll-to-roll process. | 04-29-2010 |
| 20090214899 | BATTERY LAYOUT INCORPORATING FULL METAL EDGE SEAL - A first current collector on the first surface of the substrate and a second current collector having a first surface and a perimeter. One of the first and second current collector is an anode current collector and the other is a cathode current collector. The battery also comprises a cathode material having a perimeter, the cathode material being located on the cathode current collector; an electrolyte layer having a perimeter, the electrolyte separating the cathode material from the anode current collector; an insulation layer having a perimeter, the insulation layer together with the electrolyte layer separating the anode current collector from the cathode material and the cathode current collector. A first passivation layer generally overlies at least the perimeter of the cathode material, the perimeter of the electrolyte, and the perimeter of the insulation layer, the first passivation layer being electrically coupled to the first current collector and forming a continuous metal to metal seal around a defined area of the first current collector. The first passivation layer has a via opening. A second passivation layer is electrically coupled to the second current collector through the via opening of the first passivation layer. | 08-27-2009 |
