摘要：

In situ solvothermally synthesized composite (SSC) and mechanically blended composite (MBC) of nanosized CoSb3 and multiwalled carbon nanotubes (MWNTs) were prepared and investigated as potential anode materials for Li-ion batteries. It was found that SSC exhibits an entanglement structure of nanosized CoSb3 and MWNTs and shows significantly better cycling stability than MBC. The reversible capacity of SSC electrode reaches 312 mA h g(-1) at the first cycle and remains above 265 mA h g(-1) after 30 cycles. (c) 2004 Elsevier Ltd. All rights reserved.
