“…Recently, KOH is used to activate the carbon-based electrode materials at a high temperature (~800°C), which can not only tailor the doping contents of N and O in derived graphene, but also improve its microstructure. Concretely, Xie's team have investigated the activation mechanism of KOH-coated PI film irradiating with a CW CO 2 laser (10.6 lm, 150 lm beam diameter) [223]. In the air, the activated porous LIG treated with medium concentrations of KOH exhibited the improvements in quality, wettability and doping of heteroatoms (N and O), while the LIG treated with high concentrations of KOH generated the abundant carbon atomic defects and mesoporous structures.…”

“…For instance, a group demonstrated that KOH treatment polysized in a microwave reactor can be effectively done within short time, 10 min (Feng et al 2020 ). While another group showed that laser writing is also an effective method for KOH activation treatment since it’s cost and time effective method (Liu et al 2020b ).…”

Graphic abstract Polyacrylonitrile (PAN)-based carbon precursor is a well-established and researched material for electrodes in energy storage applications due to its good physical properties and excellent electrochemical performance. However, in the fight of preserving the environment and pioneering renewable energy sources, environmentally sustainable carbon precursors with superior electrochemical performance are needed. Therefore, bio-based materials are excellent candidates to replace PAN as a carbon precursor. Depending on the design requirement (e.g. carbon morphology, doping level, specific surface area, pore size and volume, and electrochemical performance), the appropriate selection of carbon precursors can be made from a variety of biomass and biowaste materials. This review provides a summary and discussion on the preparation and characterization of the emerging and recent bio-based carbon precursors that can be used as electrodes in energy storage applications. The review is outlined based on the morphology of nanostructures and the precursor’s type. Furthermore, the review discusses and summarizes the excellent electrochemical performance of these recent carbon precursors in storage energy applications. Finally, a summary and outlook are also given. All this together portrays the promising role of bio-based carbon electrodes in energy storage applications.

“…Benefiting from the improvement of activation, the laser‐induced and activated graphene‐based IMSC present an areal capacitance of 32 mF cm −2 , ≈10 times higher than that without KOH activation. [ 143 ] Mao et al. illustrated a porous opend 3D network of laser‐induced rGO/poly(3,4‐ethylenedioxythiophene) (rGO/PEDOT).…”
