混合纳米结构集热器的概念是由硅纳米颗粒装饰的薄垂直排列的碳纳米管（CNTs）制成，为锂离子电池提供高功率密度的阳极。由于碳纳米管的有效电子传导与明确的电活性硅纳米颗粒相结合，实现了令人印象深刻的速率能力：在1.3C时达到3000 mAh g - 1，在15C时达到800 mAh g - 1。
The concept of a hybrid nanostructured collector made of thin vertically aligned carbon nanotubes (CNTs) decorated with Si nanoparticles provides high power density anodes in lithium-ion batteries. An impressive rate capability is achieved due to the efficient electronic conduction of CNTs combined with well defined electroactive Si nanoparticles: capacities of 3000 mAh g−1 at 1.3C and 800 mAh g−1 at 15C are achieved.
