The investigation of phosphoric acid treatment on the performance of hard carbon from a typical lignocellulosic biomass waste (peanut shell) is herein reported. A strong correlation is discovered between the treatment time and the structural properties and electrochemical performance in sodium-ion batteries. Indeed, a prolonged acid treatment enables the use of lower temperatures, that is, lower energy consumption, for the carbonization step as well as improved high-rate performance (122 mAh g at 10 C).
本文报道了磷酸处理对典型木质纤维素生物质废弃物（花生壳）制备的硬碳性能的影响。研究发现，处理时间与钠离子电池的结构性能和电化学性能之间存在很强的相关性。实际上，延长酸处理时间能够在碳化步骤中采用更低的温度，即更低的能耗，同时还能提高高倍率性能（在10C下为122 mAh g）。
