Designing 3D Conical-Shaped Lithium-Ion Microelectrodes
Senior undergraduate student, Daw Gen Lim, Purdue MSE BMSE, 2014 (R. Edwin García, advisor), has proposed a set of device fabrication guidelines to enable the optimization of 3D microbatteries. Architecture parameters (e.g., aspect ratio and density of cones) controlling its performance (e.g., power and energy density) have been proposed and used to rationalize emerging state-of-the-art 3D designs. The effect of the architecture and C-rate on its chemomechanical reliability is also analyzed, enabling the realization of fatigue-resistant energy storage devices.
