“…26 The microstructure and performances of the final hard carbon materials depend strongly on the nature of the precursor. 27,28 According to the different precursors, hard carbon can be divided into resin-based hard carbon, 29,30 pitch-based hard carbon [31][32][33] and biomass-based hard carbon. 12,[34][35][36] Among them, biomass-derived hard carbon represents great advantages in terms of precise nature-made structure, sustainable carbon sources, low cost as well as large-scale production.…”

The utilization of binders has severely hindered ionic diffusion and electron transfer in the traditional lithium-ion battery. Herein, a self-standing hard carbon film using nanocellulose as precursor has been constructed as binder-free electrodes via two-step thermal treatment. The cyclization and aromatization of small molecular fragments promote the formation of hyper-crosslinked framework with abundant welded junctions. Importantly, carbon nanofibers not only serve as an inter-connected conductive network for fast electron transfer, but also as an interlinked mechanical skeleton for convenient Li + diffusion and electrode structural stability. Furthermore, the optimized carbon film, with accessible redox-active carbonyl groups (C O) and abundant micropores, is beneficial for Li + accommodation. It exhibits high reversible capacity of 513.1 mAh g −1 at 50 mA g −1 and excellent cycle stability to extend over 1000 cycles without signs of decay. This study provides an efficient strategy for the design of high-performance biomass-derived anode materials with stablestructure for alkaline batteries.

“…Therefore, developing new material with outstanding performance for Na-ion batteries is of most importance and urgency. 7,11,12 A recent upsurge in the two-dimensional (2D) materials such as graphene, layered oxides, black phosphorus, and transition-metal dichalcogenides has established their prominent role of 2D materials in energy storage applications. 6,13,14 Among them, MXene, as a potential energy storage material, has received extensive attention due to its following properties: ultralarge interlayer spacing, excellent electrical conductivity, significant safety performance, large specific surface area, and high storage capacity.…”

“…Energy storage devices like lithium-ion batteries or supercapacitors have been widely used in the present stage. − With respect to Li-ion batteries, the limited content of Li ions in the Earth’s crust has restricted their development and application. − It is worth noting that Na-ion batteries with the same main group as lithium have been receiving more and more attention. − However, the radius of Na ions is much larger than that of Li ions, so the electrode materials commonly used in Li-ion batteries are not effective when used for Na-ion batteries. Therefore, developing new material with outstanding performance for Na-ion batteries is of most importance and urgency. ,, …”

Two-dimensional (2D) MXenes, including carbides, nitrides, and carbonitrides MXene, have been proved to be a possible candidate as anode materials of sodium-ion batteries. This paper focuses on the electronic properties and the electrochemical performance of nitrides MXene. First, density functional theory simulations were utilized to disclose the geometric structure and electronic properties, Na diffusion path, and storage behaviors of titanium carbonitrides Ti3CNT x , nitrides MXene Ti3N2T x , and carbides MXene Ti3C2T x with oxygen terminations, predicting the more excellent performance of Ti3N2O2 than Ti3C2O2. Also, then the structure characterization and electrochemical performance experiments of Ti3C2T x and Ti3CNT x were conducted to verify the theoretical predictions and test the cycling performances. The superior performance of Ti3N2O2 originates from the stronger connection of O–Ti–N than that of O–Ti–C, resulting in the stackings of Ti3N2O2 being tighter and the interlayer spacings being larger than that of Ti3C2O2, which is advantageous to sodiation and desodiation. The capacity of Ti3CNT x increased again to 145 mAh/g after 35 cycles at a current density of 20 mA/g, which demonstrated a better rate performance than Ti3C2T x corroborated by the diffusion barriers of the theoretical calculation results. Ti3CNT x exhibits a good cycling performance of 110 mAh/g (≈60% of the initial value) after 200 cycles, which is better than that of 87 mAh/g (≈51% of the initial value) of Ti3C2T x . It is worth noting that all these performances ensure that nitride MXene is more suitable as the anode material of Na-ion batteries than carbide MXene. These findings are conducive to expanding the MXene family and promoting their application in energy storage applications.

More recently, Lu et al explored another way to reduce pitch graphitization and suggested to pre-oxidize the precursor in order to introduce cross-linking between the Basic Structural Units (BSUs) within the structure.…”

Recently, sodium-ion batteries have been intensively studied as an alternative to lithium-ion batteries because of the abundance of sodium and its ability, for example, to answer to smart grid energy storage applications. Among all anode materials, carbonaceous materials have shown promising results, particularly hard carbons owing to their high capacity and low insertion voltage (vs. Na + /Na). However, these materials often suffer from their high cost and low initial coulombic efficiency. In this paper, we investigate an easy route of hard carbon synthesis from low-cost pitch precursor. A pre-treatment under a controlled atmosphere can hinder the graphitization of the pitch upon pyrolysis and induce an amorphous-like microstructure with high
