研究了热蒸发法制备的SnO2纳米线作为锂离子电池负极材料的可能性。在第一次放电过程中，锂离子的容量为2133 mA h g(-1)，远远大于体相SnO2的理论总容量1494 mA h g(-1)。在连续的15次循环中，可逆容量保持在1250-700 mA h g(-1)的范围内，在0.5 mA cm(-2)的恒流密度下，容量衰减率为3.89%。这些结果表明，SnO2纳米线是一种很有前途的锂离子电池负极材料。
SnO2 nanowires synthesized by thermal evaporation method are investigated as a possible anode electrode for Li-ion batteries. In the first discharge process, the capacity of Li ions is 2133 mA h g(-1), which is much more than the theoretical total capacity of the bulk SnO2, 1494 mA h g(-1). During the successive 15 cycles, the reversible capacity stays in the range of 1250-700 mA h g(-1) with a capacity fading of 3.89% per cycle at a constant current density of 0.5 mA cm(-2). These results demonstrate that SnO2 nanowires are a promising anode material for Li-ion battery applications.
