LiFeBO3, Li0FeBO3 and LiFe 0.5Mn0.5 BO3 coated with carbon were synthesized and their electrochemical properties investigated. Carbon increases dramatically the redox activity. Thus, carbon-painted LiFeBO3 shows a large discharge capacity and good cycle performance. For this compound cycled between 2 and 3.7 V, 77% of the initial capacity (156 mAh/g) is retained after 210 cycles (121 mAh/g). The electrochemical behavior of LiFe 0.5Mn0.5BO3 reveals two clear charge-discharge plateaus at 2.8 and 3.4 V. The electrochemical activity of fully delithiated Li0FeBO3 differs from that of calcite structure FeBO 3.
