Abstract

We report the fabrication of high energy Li-ion capacitor (LIC) using teak wood sawdust derived mesoporous activated carbon (AC-HBP) with electrochemically pre-lithiated graphite (LiC₆). Three interesting supercapacitor assemblies are constructed using AC-HBP to realize the high energy density. Amongst, AC-HBP paired with LiC₆ delivered a maximum energy density of ∼111 Wh kg⁻¹ compared to Li₄Ti₅O₁₂ in LIC (∼53 Wh kg⁻¹) and AC-HBP (∼37 Wh kg⁻¹) in symmetric configurations. This excellent energy density is mainly ascribed to the tailored mesoporous nature (∼67%) of the high surface area activated carbon (2108 m² g⁻¹) obtained via hydrothermal carbonization process in the presence of processing agent, benzene tetracarboxylic acid followed by physico-chemical activation.
