Strategies For The Stabilization Of Metal Anodes For Li And Na Metal Batteries, Yang Zhao
Strategies For The Stabilization Of Metal Anodes For Li And Na Metal Batteries, Yang Zhao
Electronic Thesis and Dissertation Repository
Li-metal batteries (LMBs) and Na-metal batteries (NMBs) are considered as the promising candidates to replace the conventional Li-ion batteries (LIBs) due to their high theoretical energy density. For LMBs and NMBs, Li metal and Na metal are the ultimate choices to achieve their high energy density due to the high specific capacity, low electrochemical potential and lightweight. However, as alkali metals, both Li and Na metal anodes suffer from serious challenges including 1) Li/Na dendrite formations and short circuits; 2) Low Coulombic efficiency (CE) and poor cycling performance; and 3) Infinite volume changes. This thesis mainly focuses on the design …
