摘要: Abstract Hierarchical porous carbon derived from lignin (denoted as LHPC) was prepared via a facile method. In this method, KOH acts both activating agent and template. The obtained LHPC composed of unique 3D macroporous network with mesopores micropores decorated on walls. further applied the anode material lithium ion battery displayed stable, high capacity 470 mAh g−1 after 400 galvanostatic charge-discharge cycles at current density 200 mA g−1. Furthermore, cycling stability perfect rate capability. This method for preparation offers new route series hierarchical carbons application in supercapacitors, fuel cells, batteries, etc.
