“…5g, illustrating that the supercapacitor with AH-PCs achieved an energy density peak of 11.44 W h kg −1 at a power density of 125 W kg −1 , and it sustained an energy density of 8.19 W h kg −1 at a higher power density of 5000 W kg −1 in the 6 M KOH electrolyte, which is better than most of the reported results shown in Table S5 †10–12,14,15,36,37,59–61 Additionally, after 400 000 cycles, AH-PC-based supercapacitors exhibit extremely high electrochemical stability (capacitance retention as high as 94.9% and coulombic efficiency of almost 100%) (Fig. 5h), which is better than most of the reported results, 10–15,36,37,59–61 suggesting that in real-world applications, they may be used as effective and secure energy storage components.…”

“…The inadequate specific surface areas and porosity, and deficient heteroatom retention, lead to suboptimal electrochemical performance in supercapacitors during high-rate and long-cycle operations. 6–15,35–37 The practical achievement of hundreds of thousands of cycles is still challenging, and it has been reported that the service life of carbon-based devices rarely exceeds 200 000 cycles, especially at high current rates. 38 How to increase the active sites of chitosan to increase the crosslinking degree, to effectively prepare chitosan-derived porous carbons with enhanced electrochemical performance, is still a great and critical challenge.…”

Lignin-derived porous carbons have great potential for energy storage applications. However, their traditional synthesis requires highly corrosive activating agents in order to produce porous structures. In this work, an environmentally friendly and unique method has been developed for preparing lignin-based 3D spherical porous carbons (LSPCs). Dropwise injection of a lignin solution containing PVA sacrificial templates into liquid nitrogen produces tiny spheres that are lyophilized and carbonized to produce LSPCs. Most of the synthesized samples possess excellent specific surface areas (426.6–790.5 m2/g) along with hierarchical micro- and mesoporous morphologies. When tested in supercapacitor applications, LSPC-28 demonstrates a superior specific capacitance of 102.3 F/g at 0.5 A/g, excellent rate capability with 70.3% capacitance retention at 20 A/g, and a commendable energy density of 2.1 Wh/kg at 250 W/kg. These materials (LSPC-46) also show promising performance as an anode material in sodium-ion batteries with high reversible capacity (110 mAh g–1 at 100 mA g–1), high Coulombic efficiency, and excellent cycling stability. This novel and green technique is anticipated to facilitate the scalability of lignin-based porous carbons and open a range of research opportunities for energy storage applications.

“…The issues with complicated processing and functionalization of lignin due to its heterogeneous nature are still the major challenges to be surmounted for its commercial use. Despite that, lignin-based polymer resins are still prominent materials to be used both in well-known and emerging fields, such as adhesives, [28] flame retardants, 3D-printing resins, food packaging, supercapacitor electrode materials, [29] bio-based road materials, [30] foams, [31] etc. [5,6c,26-27] The main types of cross-linking reactions utilized in lignin-based resin formulations are explained in table 1.…”

Lignin, a complex and abundant biopolymer derived from plant cell walls, has emerged as a promising feedstock for sustainable material development. Due to the high abundance of phenylpropanoid units, aromatic rings, and hydroxyl groups, lignin is an ideal candidate for being explored in various material applications. Therefore, the demand on lignin valorization for development of value‐added products is significantly increasing. This mini‐review provides an overview of lignin upconversion, focusing on its functionalization through chemical and enzymatic routes, and its application in lignin‐based polymer resins, hydrogels, and nanomaterials. The functionalization of lignin molecules with various chemical groups offers tailored properties and increased compatibility with other materials, expanding its potential applications. Additionally, the formation of lignin‐based networks, either through cross‐linking or blending with polymers, generates novel materials with improved mechanical, thermal, and barrier properties. However, challenges remain in optimizing functionalization techniques, preserving the innate complexity of lignin, and achieving scalability for industrial implementation. As lignin's potential continues to be unlocked, it is poised to contribute significantly to the shift towards more eco‐friendly and resource‐efficient industries
