THREE-DIMENSIONAL (3D) ELECTRODE ARCHITECTURE FOR A MICROBATTERY |
摘要 |
A three-dimensional (3D) electrode architecture for a microbattery includes an anode structure comprising one or more anode digits and a cathode structure comprising one or more cathode digits, the anode digits being positioned alternately with the cathode digits in an interdigitated configuration on a substrate, where each of the anode digits has a width wa and each of the cathode digits has a width wc. Each of the anode digits comprises an anode material deposited on a first current collector and extending to a height h above the first current collector, and each of the cathode digits comprises a cathode material deposited on a second current collector and extending to a height h, above the second current collector. A height-to-width aspect ratio ha/wa of the anode structure and a height-to-width aspect ratio hc/wc of the cathode structure are at least about 2. |

1. A three-dimensional (3D) electrode architecture for a microbattery, the electrode architecture comprising:
an anode structure comprising one or more anode digits and a cathode structure comprising one or more cathode digits, the anode digits being positioned alternately with the cathode digits in an interdigitated configuration on a substrate, each of the anode digits having a width wa and each of the cathode digits having a width wc, wherein each of the anode digits comprises an anode material deposited on a first current collector, the anode material extending to a height ha above the first current collector, and wherein each of the cathode digits comprises a cathode material deposited on a second current collector, the cathode material extending to a height hc above the second current collector, and wherein a height-to-width aspect ratio ha/wa of the anode structure and a height-to-width aspect ratio hc/wc of the cathode structure are at least about 2. |
