In this study, pre-lithiation through the spontaneous chemical reaction between the aryl etherification reagent was used to improve the ICE of the lignin-based negative electrode material. Our results showed that the ICE of the activated lignin-based negative electrode material was increased from 45% to 80%. It indicates that treated lignin is a promising renewable electrode material for battery applications due to of its high yield, low price, high ICE, high capacity and stable cycling. It can be used in electrochemical energy storage and conversion devices, such as supercapacitors, fuel cells, lithium ion batteries, etc.
