    • An electrode for a battery is augmented with vertically aligned carbon nanotubes, allowing both improved storage density of lithium ions and the increase electrical and thermal conductivity. Carbon nanotubes are extremely good electrical and thermal conductors, and can be grown directly on the electrode (e.g., anode or cathode) current collector metals, allowing direct electrical contact. Additionally carbon nanotubes have an ideal aspect ratio, having lengths potentially thousands of times as long as their widths, 10 to 1,000 nanometers. In an embodiment, the carbon nanotube electrode (e.g., a cathode) comprises embedded elemental sulfur, allowing both the improved retention of elemental sulfur and increase electrical conductivity. The surface of carbon nanotubes are nearly chemically identical to carbon, binding the sulfur atoms to the carbon nanotubes, preventing the "loss" of sulfur with the formation of LiS intermediate products.
    • 用电池的电极用垂直排列的碳纳米管增强,允许提高锂离子的储存密度和增加电和热导率。 碳纳米管是非常好的电和热导体,并​​且可以直接生长在电极(例如阳极或阴极)集电器金属上,从而允许直接的电接触。 另外,碳纳米管具有理想的纵横比,其长度可以是其宽度为10至1,000纳米的数千倍。 在一个实施方案中,碳纳米管电极(例如阴极)包括嵌入的元素硫,允许改善元素硫的保留并增加导电性。 碳纳米管的表面几乎与碳结合,将硫原子结合到碳纳米管上,防止形成LiS中间产物的“损失”硫。
