Confinement-stabilized Bi@NC by graphene coating enables ultrafast and stable sodium storage
Yiting Dai, Liang Liu, Ge Lin, Hong Cui, Jiacheng Shen, Jiantie XuA graphene-confined Bi@NC/rG 0.1 , synergistically stabilized by H 2 reduction, delivers ultrahigh-rate sodium storage (276 mAh g −1 at 50 A g −1 ) and exceptional cyclability in half- (92% after 3000 cycles) and full-cells (89.3% after 2000 cycles).
