摘要
用流变相反应和前驱物热分解法 ,在约 35 0℃的温度下合成了氧化亚锡基可充锂离子电池负极材料 通过XRD和电化学测试对材料进行了表征 结果表明 ,制备的两种氧化亚锡基负极材料Sn1.0 Al0 .4B0 .6P0 .4O3 .5(TABP)及Sn1.0 B0 .6P0 .4O2 .9(TBP)均为非晶态结构 ,它们都有较高的贮锂容量 。
The SnO\|based anode materials for lithium ion rechargeable batteries were synthesized through rheological phase reaction and pyrolysis of precursors at about 350℃. The products were characterized by XRD and electrochemical measurements. The results showed that the prepared samples, Sn 1.0 Al 0.4 B 0.6 P 0.4 O 3.5 (TABP) and Sn 1.0 B 0.6 P 0.4 O 2.9 (TBP), were amorphous and they exhibited large lithium storage capacities. The electrochemical properties of TBP are better than that of TABP.
