The plateau capacity of the electrode increased from 56.8 mAh/g to 236.0 mAh/g and reversible capacity up to 333.7 mAh/g because of the significant increase in platform capacity. According to the Galvanostatic Intermittent Titration Technique （GITT） analysis， the storage mechanism of sodium ions in the lignin-derived hard carbon electrode conformed to the “Adsorption-Intercalation/Filling” hybrid model.]]> 2024/7/9 8:58:16 HUA Zifeng,LI Gengchen,WU Yao,LIN Changmei,HUANG Hai,MA Xiaojuan,CAO Shilin 1true
