Abstract Details

2016, Doctor of Philosophy (PhD), Wright State University, Engineering PhD.
The future of electronic devices, such as smart skins, embedded electronics, and wearable applications, requires a disruptive innovation to the design of conventional batteries. This research was thus aimed at leveraging additive manufacturing as a means to invigorate the design of next-generation Li-ion batteries to meet the emerging requirements of flexible electronics. First, a state-of-the art approach for achieving flexible Li-ion batteries, using a robust, multi-walled carbon nanotube mat as current collector was demonstrated. A unique mechanical device was constructed to experimentally observe the correlation between mechanical fatigue and electrochemical stability. Points of failure in the conventional architecture were evaluated for improvement. Further, ink formulations were developed for printing both electrode and electrolyte membranes. Upon optimization of electrode porosity and electrical conductivity, application constraints, such as internal resistance, cycle life, and mechanical integrity, were studied to ensure maintenance of battery performance throughout the additive manufacturing process. Under similar evaluation, an electrolyte membrane fabricated using a phase inversion method with the addition of ceramic filler was revealed to impart a number of desirable performance characteristics (e.g., thermal stability, dendrite suppression) immediately upon extrusion and drying. Finally, a sequentially 3D-printed, full battery stack using these ink formulations was demonstrated to achieve targeted capacity and energy density requirements of 1 mAh cm-2 and 1.8 mWh cm-2, respectively.
