磷封装的碳纳米管已被制备出来，并作为锂离子电池的负极进行了研究。该负极性能显示出磷具有约700毫安时/克的优异可逆容量，并且在第15次充放电循环后容量保持率几乎为100%。这种优异的循环性能被认为是由于即使锂金属沉积在负极上，带有氧官能团的碳纳米管对磷仍能稳定捕获。
Phosphorus-encapsulated carbon nanotubes have been prepared and investigated as anodes for lithium ion batteries. The anode performance showed an excellent reversible capacity of ~700 mAh/g in phosphorus and capacity retention of almost 100% after charge-discharge cycling at the 15th cycle. The excellent cyclability is thought to be attributed to stable trapping of phosphorus in carbon nanotubes with oxygen functional groups even though lithium metal is deposited on the anodes.
