Sustainable resources, particularly those induced from bio-derived waste materials, can be transformed into useful nanocarbon materials with high functionality. In this study, nanoporous carbon materials (N-CMs) were fabricated from waste sawdust using a simple heating process and a carefully controlled activation process. The waste-induced N-CMs had a high specific surface area of ∼3044.6 m² g⁻¹, a nanoporous structure, and > 6 at.% heteroatoms. These properties led to high electrochemical performance with a specific capacity of ∼298 mAh g⁻¹ and excellent cycling stability over 2,000 cycles as a cathode in lithium-ion storage. Moreover, when the N-CMs were assembled with a nanostructured carbon-based anode, all full carbon-based cells could deliver high specific energy and specific power of ∼377 Wh kg⁻¹ and ∼20,247 W kg⁻¹, respectively, with a long-term cycle life of more than 1,000 cycles.

可持续资源，特别是由生物废料引起的资源，可以转化为具有高功能性的有用纳米碳材料。在这项研究中，使用简单的加热过程和精心控制的活化过程，由废木屑制成了纳米多孔碳材料（N-CM）。废物诱导的N-CM具有约3044.6 m ² g ^-1的高比表面积，纳米孔结构和> 6 at。％的杂原子。这些性能带来了较高的电化学性能，比容量约为298 mAh g ^-1作为锂离子存储中的阴极，具有超过2,000个循环的出色循环稳定性。此外，当N的CM用一个纳米结构的碳基阳极组装时，所有的全碳系细胞可以递送~377瓦公斤的高比能量和比功率^-1和~20,247W¯¯千克^-1，分别用一长期循环寿命超过1,000次循环。
