Lignin-derived carbon is regarded as one of the most promising electrochemical energy storage materials because of its sustainability, low cost and high conductivity. However, the lithium-ion storage capability of lignin-derived carbon in lithium-ion batteries (LIBs) is hampered by its disordered wine bottle-like micropores. Herein, a lignin-derived honeycomb-like porous carbon encapsulated SiO₂ (LHC/SiO₂-21) with three-dimensional interconnected honeycomb-like mesoporous structure is synthesized via a dual-template-assisted self-assembly strategy. The ordered mesoporous structure and high pore volume (2.23 cm³ g⁻¹) synergistically lead to fast lithium ions diffusion kinetics and more lithium-ion storage sites. When applied as anode materials for LIBs, LHC/SiO₂-21 exhibits a high reversible capacity of 1109 mAh g⁻¹, superior rate capability, and long cycle performance. Moreover, the high-capacity LHC/SiO₂-21 is prepared by a green approach originating from low-cost lignin and self-assembly method. Thus, lignin-derived carbon materials have the great potential for the application in energy storage.

木质素衍生的碳因其可持续性，低成本和高电导率而被认为是最有前途的电化学储能材料之一。但是，木质素来源的碳在锂离子电池（LIB）中的锂离子储存能力受到其无序的酒瓶状微孔的阻碍。在此，通过双模板辅助自组装策略合成了具有三维互连蜂窝状介孔结构的木质素衍生蜂窝状多孔碳包埋SiO ₂（LHC / SiO ₂ -21）。有序的介孔结构和高孔体积（2.23 cm ³  g ^-1）协同作用会导致快速的锂离子扩散动力学和更多的锂离子存储位点。当用作LIB的负极材料时，LHC / SiO ₂ -21具有1109 mAh g ^-1的高可逆容量，优异的倍率能力和长循环性能。此外，高容量的LHC / SiO ₂ -21是通过低成本的木质素和自组装方法衍生的绿色方法制备的。因此，木质素衍生的碳材料在储能方面具有巨大的潜力。
