摘要

A carbon-incorporated LiMnBO3/boron oxide composite (LMB/BxOy@C) is prepared as an advanced anode material for lithium-ion batteries (LIBs). The prepared LMB/BxOy@C can deliver a reversible capacity of about 362.5 mAh g(-1) at a low current density of 0.04 A g(-1). When cycled at 2.0 A g(-1), the specific capacity increases from 159.7mAh g(-1) at the 100th cycle to 263.3 mAh g(-1), which still maintains at 259 mAh g(-1) after 1000 cycles. The excellent cycling performance and boosting effect of capacity should be due to the existence of conductive carbon network, the inactive boron oxide to provide outstanding structural stability, and the activation of the transformation between Mn2+ and Mn4+ during cycling. The preliminary result illustrates that the prepared LMB/BxOy@C could be a promising anode material for LIBs. (C) 2018 Elsevier B.V. All rights reserved.
