abstract = {Sodium-ion batteries (SIBs) are the most promising
replacement for lithium-ion batteries (LiBs) owing to the
low price and availability of sodium. Cathode materials for
SIBs have similarity to those for LIBs, including the most
popular type, namely layered metal oxides (NaxMO2). However,
capacity and stability of currently known NaxMO2 materials
need to be improved to meet the requirement for practical
applications. In this work, multiscale modeling approaches
combining electrostatic analysis, density functional theory
(DFT) calculation, GW approximation [1], thermodynamics
consideration, and finite element simulation, have been
applied to design novel NaxMO2 materials. It is shown that
calculated magnetic moment using DFT with hybrid
exchange-correlation functionals can predict redox mechanism
(i.e. capacity) of cathode materials [2,3]. Moreover, it is
shown that how multiscale-modeling approaches can be used to
predict stability of cathode materials. Finally, a combined
theoretical/experimental work on design of NaxMO2
compositions with high capacity and stability is presented.
