Surface Modification Of Electrode Materials For Lithium-Ion Batteries, Biwei Xiao
Electronic Thesis and Dissertation Repository
The development of lithium-ion batteries (LIBs) has been hampered by the intrinsic limitations of the electrode materials. High-performance LIBs demand electrode materials with fast lithium/electron diffusion rate, stable surface chemistry and high specific capacity. Surface modification by atomic layer deposition (ALD) is an essential method to optimize the performance of the electrode materials. The research in this thesis aims at achieving high-performance LIBs via surface modification and understanding the mechanisms via synchrotron radiation.
Firstly, by applying ALD FePO4 on LiNi0.5Mn1.5O4 (LNMO), we successfully alleviated the electrolyte decomposition under high voltage by using the electrochemically …
