Two-dimensional nanocarbons are intriguing functional materials for energy storage. However, the serious aggregation problems hinder their wider applications. To address this issue, we developed a unique two-dimensional hierarchical carbon architecture (2D-HCA) with ultrasmall graphene-like carbon nanosheets uniformly grown on hexagonal carbon nanoplates. The obtained 2D-HCA shows an interconnected porous structure and abundant heteroelement doping. When employed as anode for lithium ion batteries, it exhibits a high discharge capacity of 748 m Ah g even after 400 cycles at 2 A g.
二维纳米碳是一种很有前途的储能功能材料。然而，严重的聚集问题阻碍了它们的广泛应用。为了解决这个问题，我们开发了一种独特的二维分层碳结构（2D-HCA），具有均匀生长在六方碳纳米片上的超小石墨烯状碳纳米片。所得到的 2D-HCA 具有互连的多孔结构和丰富的杂元素掺杂。将其用作锂离子电池的阳极时，即使在 2 A g 的电流密度下循环 400 次后，仍具有 748 mAh g 的高放电容量。
