| 摘要 |
The invention concerns a quick-recharge energy storage device having a sufficient capacitance resulting from the combination of a micro-battery (1) and at least a micro-supercapacitor (7) connected between two terminals of an integrated circuit (13). The integrated circuit, powered by the micro-battery, controls the rapid (less than one second) charge of the micro-supercapacitors from an external power source (14). The micro-supercapacitor can be connected in parallel with the micro-battery so as to subsequently recharge the micro-battery for the required time. The micro-battery provides sufficient power capacity, while the micro-supercapacitors enable high recharging speeds, compatible with various applications (smart cards, smart labels, microsystem powering and the like). The micro-battery (1) and the micro-supercapacitors (7) are preferably formed on the same substrate, either adjacent, or stacked, The connection is series of several micro-supercapacitors (7a, 7b, 7c) provides sufficient voltage for charging the micro-battery. |
