“…As illustrated in Figure 3(b,c) [35], these amazing structures can be inherited by choosing appropriate processes, producing morphology-controllable materials with structural specificity, complexity and unique functionality for energy and environment applications [42]. Although the applications of biomass materials are different, the fundamental challenge is always the same-how to improve performance by optimizing their structures.…”

Electrochemical energy storage devices, such as supercapacitors and batteries, have been proven to be the most effective energy conversion and storage technologies for practical application. However, further development of these energy storage devices is hindered by their poor electrode performance. Carbon materials used in supercapacitors and batteries are often derived from nonrenewable resources under harsh environments. Naturally abundant biomass is a green, alternative carbon source with many desired properties. This review article presents state of the art of renewable carbon materials derived from natural biomasses with an emphasis on their applications in supercapacitors and lithium-sulfur batteries. IMPACT STATEMENTThis review paper provides a comprehensive understanding for obtaining renewable carbons from natural biomass precursors via various activation methods for electrochemical energy storage application, especially for supercapacitor and lithium sulfur battery.

“…2a-c it can be observed that the surface of the activated carbon clearly exhibits a well-developed porous structure that resembles 3D honeycombs. The intercalation of metallic K during KOH activation and its removal during carbonization resulted in the porous structure of activated carbon [15]. These interconnected pores facilitate the rapid transmission of ions and act as effective reservoirs for the electrolytes.…”

Biomass‐Derived Activated Carbon for High‐Performance Supercapacitor Electrode Applications

Activated carbon is the most widely used electrode material in electrochemical double-layer capacitors. Cashew nutshell-derived activated carbon (CNSAC) exhibits a highly porous structure with reasonable surface area and high pore volume, which indicates that it is a good electrode material. Electrochemical characterizations confirmed the formation of the electric double layer in the system with high specific capacitance and excellent retention in capacitance even after thousand cylces of charge/discharge. It is found that CNSAC has great potential as a low-cost and environmentally friendly electrode material for highly efficient supercapacitors.

“…Consequently, natural, organic, and agricultural wastes, such as corncob [23], wood [24], rice husks [25], olive stones [26], sucrose [27], and jute [28], have been explored as biomass sources for the production of activated carbons (ACs) [29] with high specific surface areas (SSAs) that are connected to a very determined porosity, both of which are basic parameters for H 2 storage [30].…”

Pinecone-Derived Activated Carbons as an Effective Medium for Hydrogen Storage

et al. 2020

Pinecones, a common biomass waste, has an interesting composition in terms of cellulose and lignine content that makes them excellent precursors in various activated carbon production processes. The synthesized, nanostructured, activated carbon materials show textural properties, a high specific surface area, and a large volume of micropores, which are all features that make them suitable for various applications ranging from the purification of water to energy storage. Amongst them, a very interesting application is hydrogen storage. For this purpose, activated carbon from pinecones were prepared using chemical activation with different KOH/precursor ratios, and their hydrogen adsorption capacity was evaluated at liquid nitrogen temperatures (77 K) at pressures of up to 80 bar using a Sievert’s type volumetric apparatus. Regarding the comprehensive characterization of the samples’ textural properties, the measurement of the surface area was carried out using the Brunauer–Emmett–Teller method, the chemical composition was investigated using wavelength-dispersive spectrometry, and the topography and long-range order was estimated using scanning electron microscopy and X-ray diffraction, respectively. The hydrogen adsorption properties of the activated carbon samples were measured and then fitted using the Langmuir/ Töth isotherm model to estimate the adsorption capacity at higher pressures. The results showed that chemical activation induced the formation of an optimal pore size distribution for hydrogen adsorption centered at about 0.5 nm and the proportion of micropore volume was higher than 50%, which resulted in an adsorption capacity of 5.5 wt% at 77 K and 80 bar; this was an increase of as much as 150% relative to the one predicted by the Chahine rule.
