摘要：

A Li2FeSiO4/C nanocomposite is prepared via solvothermal method in combination with carbon coating technology. The as-prepared L nanocomposite is a single phase Li2FeSiO4 with nano-tickness coated carbon layer and connected by the mutual cross-linked carbon conductive matrix. As cathode material for lithium ion battery, the composite delivers a discharge capacity of 154 mAh g(-1) at 1 C and exhibits good rate capability with a discharge capacity of 106 mAh g(-1) at the rate of 10 C, which is ascribed to the small particle size and enhanced electronic conductivity using carbon coating technology. The asprepared Li2FeSiO4/C nanocomposite also behaves a good cycling stability with capacity retention of over 100 cycles. (C) 2014 Elsevier Ltd. All rights reserved.
