Rational Design Of Cell Configurations For High-Performance Na-O2 Batteries, Xiaoting Lin
Electronic Thesis and Dissertation Repository
Na-O2 batteries are considered as the promising candidates for electric vehicles due to their ultrahigh theoretical energy densities. However, state-of-the-art Na-O2 batteries suffer from serious challenges including 1) pore clogging and insufficient O2 transportation within the air electrode; 2) degradation of air electrode, 3) Na dendrite growth; and 4) Na corrosion induced by O2/O2- crossover. This thesis, therefore, focuses on rational design of cell configurations to address these problems and understanding the insight mechanisms.
3D printing of “O2 breathable” air electrodes for Na-O2 batteries were first developed. The unique air electrode …
