Three-dimensional flower-like α-Co(OH)2 architectures assembled by nanoplates for lithium ion batteries

The electrochemical properties of hierarchically three-dimensional (3D) flower-like α-Co(OH)2 architectures assembled by nanoplates have been studied for the first time. When tested as anode materials for lithium ion batteries, these hierarchically 3D flower-like architectures exhibit excellent electrochemical performance with high reversible capacity, excellent cycling stability, and good rate capability. The anode electrode made of 3D flower-like α-Co(OH)2 delivered a high capacity of 1765 mA h/g for the first cycle. The results show that the 3D flower-like α-Co(OH)2 architectures is a potential anode material for high-performance lithium ion batteries (LIBs). The results achieved in this work provide valuable insights into the development of new anode materials for high-performance lithium ion batteries.
