DESCRIPTION:(zoom lecture link comes shortly before) An ever-increas
ing demand for better batteries (with high voltage\, high capacity\, fast
charging\, and high safety) has set extraordinarily high standards for ele
ctrolyte materials\, which are far beyond the realm of conventional nonaqu
eous electrolyte design based on 1 mol L-1 (M) LiPF<
sub>6 and ethylene carbonate (EC). Generally\, further increasing sa
lt concentration over the conventional 1 M increases the viscosity and dec
reases the ionic conductivity\, both of which are unfavorable for battery
electrolytes in terms of reaction kinetics. However\, various unusual func
tions have been recently discovered at high salt concentrations (over 3 M)
(Fig. 1)\, including i) high reduction stability\, ii) high oxidation sta
bility\, iii) fast electrode reactions\, iv) high safety\, v) wide liquidu
s temperature range\, and vi) prevention of Al corrosion at high potential
s\, etc. As a result\, concentrated nonaqueous and aqueous solutions are e
merging as a new class of liquid electrolytes for advanced batteries. In t
his talk\, I will introduce various unusual functions of concentrated elec
trolytes\, which are not shared by conventional dilute electrolytes\, disc
uss the mechanism from the viewpoint of their unique ion-solvent coordinat
ion structures\, and present new electrolyte design strategies to advanced
batteries. Reference 1. Y. Yamada et al.\, Nat. Energy\, 4\, 269 (
