Biomass derived functional carbon materials for supercapacitor applications
Abstract
Biochar produced from the thermochemical conversion of biomass, provides a green and sustainable platform for the preparation of various functional carbon materials (porous carbon, heteroatom doped biochar, carbon nanotubes, graphene, carbon quantum dots, etc.) towards advanced application. Their preparation involves the physical as well as chemical activation of biochar or directly from the biomass. The inherent versatile physicochemical properties of these versatile materials have been explored for the construction of the electrochemical energy storage devices like supercapacitors. In the present review, the various methodologies for the preparation of various biomass-derived carbon materials are summarized. Further utilization of these materials in supercapacitor electrodes and the properties associated with their charge storage ability, along with associated challenges and perspectives are also discussed.

A high pyrolysis temperature produces a graphite-like structure with high electrical conductivity, which is favorable for biochar application as an EDLC.
“Besides, a high pyrolysis temperature produces a graphite-like structure with high electrical conductivity, which is also favorable for biochar application as an EDLC (Keiluweit et al. 2010; Rawat et al. 2022).”

Low ash and high temperature biochars are suitable for energy storage.
“Low ash and high temperature biochars are suitable to be used for soil GHG emission mitigation (Lyu et al. 2022), CCUS (Jung et al. 2019), cement additive (Danish et al. 2021), and energy storage (Rawat et al. 2022) due to high carbon stability and high adsorption capacity.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
