锂离子电池（LIBs）需要全新和先进的材料来缓解化石燃料枯竭的压力。具有可控结构的碳材料由于其优越的性能被认为是锂离子电池极具潜力的负极材料。本文通过将普通表面活性剂石墨化，一步合成了一种由超薄碳纳米片（CNCs@CNSs）支撑的三维碳纳米笼结构。超薄碳纳米片的厚度为1.6 nm，其上分散有中空的碳纳米笼以防止堆积。作为碳纳米笼与二维（2D）碳纳米片的首次结合，3D杂化物具有优异的锂离子电池性能，在0.5 C时具有650 mAh g−1的可逆容量，且容量损失很少。在10℃下，500次循环后10分钟内快速充电容量达到580 mAh g - 1，这为锂离子电池的发展提供了广阔的前景。
Lithium-ion batteries (LIBs) call for brand new and advanced materials to alleviate the pressure on depletion of fossil fuels. Carbon materials with controlled structures are considered to be potential anode materials of LIBs due to their desirable advantages. Herein, a novel three dimensional (3D) structure of carbon nanocages supported by ultrathin carbon nanosheets (CNCs@CNSs) has been synthesized through a facile one-step route by graphitizing common surfactant. The ultrathin carbon nanosheets possess a thickness of 1.6 nm with hollow carbon nanocages dispersing on them to prevent the stacking. As the first combination of carbon nanocages with two dimensional (2D) carbon nanosheets, the 3D hybrids show excellent LIB performances and exhibit a reversible capacity of 650 mAh g−1at 0.5 C with rare capacity loss. Fast charging in 10 min with a high capacity of 580 mAh g−1at 10 C after 500 cycles has also been exploited, which presents broad prospects for the advancement of LIBs.
