1. A 3D self-supporting thick carbon electrode derived from wood-based cellulose is proposed for high areal and volumetric energy density of supercapacitor from a mild, simple, and green enzymolysis treatment.
2. The assembled symmetry supercapacitor from the thick carbon electrode can realize the high areal/volumetric energy density of 0.21 mWh cm−2/0.99 mWh cm−3 with excellent stability of 86.58% after 15 000 long-term cycles at 20 mA cm−2.
3. This strategy provides a new research idea for realizing multi-functional application with high specific surface area.
The article is overall reliable and trustworthy as it provides detailed information about the proposed method for designing energy storage devices from thick carbon electrodes with high areal/volumetric energy density via a simple and green way. The article also presents evidence to support its claims, such as the high specific surface area (1418 m2 g−1) and abundant active sites on the surface of wood-derived hierarchically porous structures and enzymolysis-induced micropores and mesopores, which enable the assembled symmetry supercapacitor to realize the high areal/volumetric energy density of 0.21 mWh cm−2/0.99 mWh cm−3 with excellent stability of 86.58% after 15 000 long-term cycles at 20 mA cm−2.
However, there are some potential biases in the article that should be noted, such as not presenting both sides equally or exploring counterarguments to its claims, as well as possible promotional content that could be seen as biased towards certain products or services mentioned in the article. Additionally, there is no mention of any risks associated with this method or any potential drawbacks that could arise from using it, which should be taken into consideration when evaluating its trustworthiness and reliability.
