“…However, the higher pyrolysis temperature not only reduces the specific surface area of the material and the reactive sites, but also reduces the interlayer spacing, which is not conducive to the fast insertion/extraction of sodium/potassium ion. 8,[15][16][17] On the basis of the previous research experience, the carbonization temperature of the precursor material is set to 1200°C. The TGA results show that the carbon yield rate of the CMGL is about 30%, and from an ecological and economic point of view, it has broad application prospects.…”

Hard carbon materials are characterized by having rich resources, simple processing technology, and low cost, and they are promising as one of the anode electrodes for commercial applications of sodium-/potassium-ion batteries.Simultaneously, exploring the alkali metal ion storage mechanism is particularly important for designing high-performance electrode materials. However, the structure of hard carbon is more complex, and the description of energy storage behavior is quite controversial. In this study, the Magnolia grandiflora Lima leaf is used as a precursor, combined with simple pyrolysis and impurity removal processes, to obtain biomass-derived hard carbon material (carbonized Magnolia grandiflora Lima leaf [CMGL]). When it is used as an anode for sodium-ion batteries, it exhibits a high specific capacity of 315 mAh/g, and the capacity retention rate is 90.0% after 100 cycles. For potassium-ion batteries, the charge specific capacity is 263.5 mAh/g, with a capacity retention rate of 85.5% at the same cycling. Furthermore, different electrochemical analysis methods and microstructure characterization techniques were used to further elucidate the sodium/potassium storage mechanism of the material. All the results indicate that the high potential slope region represents the adsorption/desorption characteristics on the surface active sites, whereas the low-potential quasiplateau region belongs to the ion insertion/extraction in the graphitic microcrystallites interlayer. It is noteworthy that potassium ion is randomly

“…Conversely, hard or nongraphitizable carbons are proven to be one of the most suitable materials for SIB anodes, as noted by the abundance of literature on this topic. ,− Although hard carbons can be synthesized using several raw materials, their production from waste or end-of-life materials has recently received considerable attention. Different types of waste including bio, ,− ,− plastics, and rubber tires have been used to synthesize such hard carbons, and high capacities between 200 and 250 mAh g –1 have been achieved when used as active anode materials in SIBs.…”

Selectively resourcing electrode components can provide a significant advantage in the uptake of next generation battery systems especially considering the performance of currently incumbent lithium-ion battery technology. This work systematically explores the use of a waste stream to generate electrode components and the influence that treatment and preparation factors have on electrochemical performance. A series of carbonaceous materials derived from waste rubber tires are prepared, involving pyrolysis at 700 and 900 °C as well as physical activation using a feed of CO 2 gas. Results from Raman spectroscopy and X-ray powder diffraction (XRD) show an increase in graphitic character and larger particle size distribution of the carbon with increasing temperatures of pyrolyzation. They also reveal the impact of air and moisture on the evolution of crystalline impurities such as ZnS, CaCO 3 , and Ca(OH) 2 , and consequently their impact on the evolution of the carbon morphology. Galvanostatic cycling of Na-ion and Li−S cells involving the pyrolyzed rubber tires as an electrode component reveal different priorities as to which parameters to improve when designing materials for different cell systems. While higher specific capacities are achieved with more graphitic carbon morphologies in Na half-cells (300 mAh g −1 discharge capacity maintained after 20 cycles at 10 mA g −1 ), less graphitic morphologies were observed to reduce capacity fading experienced in Li−S cells (1003 mAh g −1 discharge capacity maintained after 18 cycles at 167.2 mA g −1 , ∼ 76% of initial value). Ex situ Raman, XRD, and X-ray absorption near-edge structure (XANES) spectroscopies were used to elucidate the mechanisms involved in post electrochemical treatment. This work highlights a pathway to use waste tires to generate valuable electrode components (active material in Na half-cells and S hosts in Li−S cells), and a similar methodology could be applied to other waste streams.

“…[9] The nonmetal elements in the precursor can be directly fixed on the carbon framework to prepare intrinsic heteroatoms doping carbon materials. Many biomass precursors such as rice husk, [10] Setaria viridis, [11] peanut shell, [12] and bagasse [13] have been developed into promising anode materials. However, they still face low initial coulombic efficiency and high cost.…”

Hard carbon is one of the most promising anode materials for sodium-ion batteries (SIBs). However, it still faces the obstacle of low reversible capacity. Modifying the carbon skeleton with heteroatoms is an effective method to improve the electrochemical properties of carbon electrodes. Herein, cocklebur fruit, a plant which is rich in natural alkaloids, is selected as the precursor to prepare N/O co-doped hard carbon. The obtained sample pyrolyzed at 1100 °C (H1100) can exhibit 366.07 mAh g À 1 specific discharge capacity and 69.08 % initial coulombic efficiency. The balance between the suitable configuration of N/ O groups and graphitization forms a carbon material with a high sodium-ion storage capability. The storage mechanism is analyzed by cyclic voltammetry (CV), differential capacity (dQ/ dV), galvanostatic intermittent titration technique (GITT), and ex-situ Raman. The results show that the sodium ions are first adsorbed on defect sites, then filled with micropores and embedded in graphite sheets.
