“…Ramesha and Babu achieved a capacity value of 1169 mAh g −1 at 0.2 C and retained 898 mAh g −1 after 200 cycles, and 454 mAh g −1 at 4 C, for the same number of cycles . Finally, Pietrzak and co‐workers obtained a specific discharge capacity of 829 mAh g −1 at 0.05 C and accomplished 50 cycles with a capacity value of 712 mAh g −1 . In comparison with these important studies and even with very relevant recent reports of non‐biomass‐derived carbon cathodes, such as that reported by Carbone and co‐workers, in this study we have obtained higher capacity values, lower loss capacity values in cycling, and long cyclability, even at high discharge rates.…”

“…They found that using a carbon/melamine ratio of 1:15 w / w can produce an excellent cathode material . Pietrzak and co‐workers (2020) reported a composite sulfur cathode using a hierarchical carbon obtained from waste PET bottles (through K 2 CO 3 activation) . Practically all carbon reported for this application has been obtained by controlled pyrolysis of the waste (or biomass) or by using chemical (NaOH, KOH, H 3 PO 4 , ZnCl 2 , K 2 CO 3 , KHCO 3 ) or physical activating agents (carbon dioxide flow, steam) .…”

The development of renewable energy sources requires the parallel development of sustainable energy storage systems because of its noncontinuous production. Even the most‐used battery on the planet, the lithium‐ion battery, is reaching its technological limit. In light of this, lithium–sulfur batteries have emerged as one of the most promising technologies to address this problem. The use of biomass to produce cathodes for these batteries addresses not only the aforementioned problem, but it also reduces the carbon footprint and gives added value to something normally considered waste. Here, the production, by simple and nonactivating pyrolysis, of a carbon material using the abundant “after‐boiling waste” derived from beer brewing is reported. After adding a high sulfur loading (70 %) to this biowaste‐derived carbon by the “melt diffusion” method, the sulfur–carbon composite is used as an effective cathode in Li–S batteries. The cathode shows excellent performance, reaching high capacity values with long‐term cyclability at high current—847 mAh g−1 at 1 C, 586 mAh g−1 at 2 C, and even 498 mAh g−1 at 5 C after 400 cycles—drastically reducing capacity loss to values approaching 0.01 % per cycle. This work demonstrates the possibility of obtaining low‐cost, highly sustainable cathodic materials for the design of advanced energy storage systems.

“…In addition to Na half-cell technologies, there is also profitability of waste-derived carbons to be used as electrode components for lithium–sulfur (Li–S) cells. − While the capacity source of Li–S cells is reliant on sulfur-containing materials rather than carbon, the incorporation of a carbon framework as a component in the electrode is often necessary for the Li–S cell to be sufficiently conductive for current to pass through due to the insulating nature of sulfur. Reports focusing on the design of these carbon frameworks for Li–S cell electrodes also typically focus on the functionality of these materials as a means to physically confine redox-active sulfur species, thus mitigating the loss of active material from shuttling in the electrolyte. − …”

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.

In the last few decades, there has been an increasing demand for low-cost raw materials and environmentally eco-friendly end products. This demand stimulated a growing interest in natural particles as potential reinforcement materials for composite manufacturing. In this paper, we introduce organic date-seed nanofillers (DSN) as reinforcement materials for the development of enhanced polymer nanocomposites. We particularly investigate the effect of these nanoparticles on two types of polymer base materials, namely medium-density polyethylene (MDPE) and polyethylene terephthalate (PET). A collection of MDPE and PET nanocomposite samples with DSN content ranging from 0.0–0.75 wt% has been prepared using a hot compression method. The MDPE-DSN and PET-DSN nanocomposite structures were analyzed using a scanning electron microscope (SEM), energy-dispersive X-ray analysis (EDXA), and Fourier-transformed infrared spectroscopy (FTIR). The mechanical characteristics of these nanocomposites were experimentally examined through wear loss and Vickers micro-hardness tests. The experimental results show that the MDPE-DSN composite is chemically more stable than the PET-DSN one. Moreover, the MDPE-DSN nanocomposite shows enhanced hardness and wear resistance properties, while the PET-DSN one shows less noticeable enhancements. The best enhancements were obtained with a DSN reinforcement of 0.75 wt%., and a normal load of 10 N. As well, the experimental outcomes show a good agreement with theoretical predictions. In general, the DSN material enhances the mechanical properties of polymer materials and reduces their economic costs.
