摘要：

Cobalt-based layered metal compound (Co(OH)(OCH3)) nanoplatelets synthesized by a facile solvothermal method were systemically characterized and investigated as an anode material for Li-ion batteries for the first time. It can deliver a high capacity of 1150 mA h g(-1) at 100 mA and stay stable even after 160 cycles. It also shows high rate performance and reversibility. Its good electrochemical performance might be attributed to the unique layered structure with large layer spacing, 2D nanoplatelet-like morphology, and the void space between the nanoplatelets. The present synthesis strategy develops a potential candidate for anode materials with good performance for lithium-ion batteries. (C) 2017 Elsevier B.V. All rights reserved.
