Carbonaceous materials have been accepted as a promising family of anode materials for lithium‐ion batteries (LIBs) owing to optimal overall performance. Among various emerging carbonaceous anode materials, hard carbons have recently gained significant attention for high‐energy LIBs. The most attractive features of hard carbons are the enriched microcrystalline structure, which not only benefits the uptake of more Li+ ions but also facilitates the Li+ ions intercalation and deintercalation. However, the booming application of hard carbons is significantly slowed by the low initial Coulombic efficiency, large initial irreversible capacity, and voltage hysteresis. Many efforts have been devoted to address these challenges toward practical applications. This paper focuses on an up‐to‐date overview of hard carbons, with an emphasis on the lithium storage fundamentals and material classification of hard carbons as well as present challenges and potential solutions. The future prospects and perspectives on hard carbons to enable practical application in next‐generation batteries are also highlighted.

“…Francisco et al reported that DESs have high lignin solubility and very poor or negligible cellulose solubility, [69] and the properties of DESs can be easily tuned by changing the HBDs and HBAs. [70] Mechanism investigation revealed that the functional groups in the DESs significantly affected their ability to dissolve lignin, [71] and they evaluated the potential of DESs for lignin processing more closely. Jablonský et al found that the best fractionation of wheat straw (based on the selectivity of lignin removal) was a DES composed of ChCl with lactic acid (1 : 10) compared with choline chloride with urea (1 : 2), malonic acid (1 : 1), lactic acid (1 : 9; 1 : 10), malic acid (1 : 1).…”

Lignin, as the most abundant aromatic biopolymer in nature, has attracted great attention due to the complexity and richness of its functional groups for value‐added applications. The yield of production of lignin and the reactivity of prepared lignin are very important to guarantee the study and development of lignin‐based chemicals and materials. Various fractionation techniques have been developed to obtain high yield and relatively high‐purity lignin as well as carbohydrates (hemicelluloses and celluloses) and to reduce the condensed and degraded nature of conventional biorefinery lignin. Herein, novel and efficient biomass fractionation and lignin fractionation towards lignin valorization are summarized and discussed.

“…This structure makes it possible for lignin to form uniform hydrophilic nano-micelles in aqueous solutions [ 46 ]. DES has been proven to solubilize lignin effectively [ 47 , 48 , 49 ], and ChCl and ETA are the most promising candidates for industrial applications because of their low viscosity, environmentally friendly and biodegradable nature. In this regard, herein we propose DES composed of ChCl and ETA as a novel dissolution system for the LNPs preparation.…”

A novel and effective green system consisting of deep eutectic solvent (DES) was proposed to prepare lignin nanoparticles (LNPs) without any lignin modification. The LNPs are obtained through the dialysis of the kraft lignin-DES solution. The particle size distribution, Zeta potential and morphology of the LNPs are characterized by using dynamic light scattering (DLS), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The average diameter of LNPs is in the range 123.6 to 140.7 nm, and the LNPs show good stability and dispersibility in water. The composite beads composed of LNPs and sodium alginate (SA) are highly efficient (97.1%) at removing methylene blue (MB) from the aqueous solution compared to 82.9% and 77.4% by the SA/bulk kraft lignin composite and pure SA, respectively. Overall, the LNPs-SA bio-nanocomposite with high adsorption capacity (258.5 mg/g) could be useful in improving water quality and other related applications.
