在由非离子表面活性剂制成的溶致液晶存在下，电沉积了一种介孔锡阳极。介孔结构的引入对Li离子充放电循环过程中Sn的体积变化有很好的调节作用。在1℃速率下，介孔锡阳极在第100次循环时的放电容量高达425 mA h g(-1)，在5℃速率下，在第100次循环时的放电容量高达320 mA It g（-1）。
A mesoporous Sn anode was electrodeposited in the presence of lyotropic liquid crystals made of nonionic surfactants. The introduction of mesoporous structure was effective for the accommodation of volume change of Sn during charge and discharge cycling of Li ions. The discharge capacity of the mesoporous Sn anode at 1 C rate was as high as 425 mA h g(-1) at the 100th cycle, and that was as high as 320 mA It g(-1) at the 100th cycle even though at 5 degrees C rate.
