摘要：

In this paper, a low-cost and environmental friendly synthesis strategy is proposed to fabricate nitrogendoped biomass-based ultra-thin carbon nanosheets (N-CNS) with interconnected framework by using soybean milk as the carbon precursor and sodium chloride as the template. The interconnected porous nanosheet structure is beneficial for lithium ion transportation, and the defects introduced by pyridine nitrogen doping are favorable for lithium storage. When used as the anodes for lithium-ion batteries, the N-CNS electrode shows a high initial reversible specific capacity of 1334 mAh g(-1) at 50 mA g(-1), excellent rate performance (1212, 555 and 336 mAh g(-1) at 0.05, 0.5 and 2 A g(-1), respectively) and good cycling stability (355 mAh g(-1) at 1 A g(-1) after 1000 cycles). Furthermore, this study demonstrates the prospects of biomass and soybean milk, as the potential anode for the application of electrochemical energy storage devices. (C) 2017 Elsevier B.V.
