Herein, highly dispersed 10-nm lithiophilic silver nanoparticles (AgNPs) were synthesized and decorated on 3D graphene aerogel supporting materials. The prelithiated AgNPs/3D graphene aerogel exhibits a high specific capacity of 1589 mAh/g at 0.1 A/g with a high initial coulombic efficiency (ICE) of ca. 93% and a long cycling stability over 500 cycles. A Li-ion battery cell using the prelithiated AgNPs/3D graphene aerogel with a finely tuned Ag content of 0.52 at.% as the anode and the Ni-rich LiNi0.88Co0.09Al0.03O2 as the cathode exhibits a high energy density of -290 Wh/kg at 0.1 C. This new anode material may be a useful high-energy anode for next-generation Li-ion batteries. [ABSTRACT FROM AUTHOR]
