Abstract

In this paper, micro-spherical CoCO3 powders have been synthesized through the hydrothermal method. The specific surface area is 1.48 m2 g-1 and the average diameter is about 5.0 mu m. Measured by the electrochemical tests as anode materials for lithium-ion batteries, the high performance has been proved: the initial discharge and charge capacities are 1669.3 mA h g-1 and 1099.8 mA h g-1 at 200 mA g-1, and the discharge capacity retention ratio (vs. the second discharge capacity) is about 64.5% after 20 cycles, then the reversible capacity nearly keeps a constant between 700.0 mA h g-1 and 600.0 mA h g-1 from the 20th cycle to the 66th cycle. It indicates that the CoCO3 powders maybe possess the potential application in this field. © 2014 Elsevier B.V. All rights reserved.
