CBE PhD Dissertation Defense | 3D Porous High Areal Capacity Lithium-ion Micro-Batteries Enabled by Electrochemical Techniques

November 18 at 3:00 PM - 5:00 PM

Abstract:

This study involves design and fabrication of scalable, high surface area, and porous 3D metal network-based Li-ion micro-batteries with energy and power that meet the demands of commercial microelectronics. A facile high current hydrogen-templated electroplating technique is utilized to generate 3D structures millimeter scale in z-direction through a facile route, which serve as the scaffolds and current collectors for battery electrodes. A solid polymer electrolyte or gel electrolyte was utilized to increase stability and safety of the energy storage device. Areal capacity high as 30 mAh/cm 2 with stable cycling performance has been demonstrated on the half-cell level, which can be attributed to the high surface area and low tortuosity from the porous electrodes.
