▎ 摘　　要

Prussian blue analogues (PBAs) have attracted increasing attention in energy research due to their open frameworks and short channels. However, the practical application of PBAs as anode materials for lithium-ion batteries (LIBs) is severely limited by their low capacity and poor cycling performance. In this work, a Mn-Fe based Prussian blue analogue@reduced graphene oxide (Mn-PBA@rGO) composite is prepared via an in-situ synthesis process to maximum using the residual manganese ions in the GO suspension. The Mn-PBA nanoparticles (NPs) anchor tightly on the rGO layers that form a conductive network in the composite. The forceful synergistic effect between the highly conductive N-doped rGO layers and Mn-PBA NPs can efficaciously mitigate the structural collapse and aggregation during the insertion and extraction of Li+. Because of above merits, the Mn-PBA@rGO composite exhibits a high reversible capacity of 1167.7 mAh g(-1) at a current density of 0.1 A g(-1) and superior rate capability, delivering capacities of 844.0, 594.5, and 400.1 mAh g(-1) at 3, 5, and 10 A g(-1), respectively. The specific capacities at 3, 5 and 10 A g(-1) can be equal to the initial one even after 1000 cycles, thus indicating that it is a promising anode material for LIBs. (C) 2018 Elsevier Ltd.
