Fast magnesiation kinetics in α-Ag2S nanostructures enabled by an in situ generated silver matrix†
Abstract
Here we first present a novel cathode material of α-Ag2S for rechargeable Mg batteries. Due to the unique cation displacement reaction mechanism and the in situ generated uniformly distributed silver matrix, α-Ag2S nanostructures deliver remarkably improved magnesiation kinetics compared to conventional transition metal sulfides.
