However, their inherent disadvantages, such as leakage during melting, low thermal conductivity, poor photothermal response, and electrical insulation, have considerably limited their practical application in solar energy utilization and electrothermal conversion systems. In this study, we propose for the first time the design and fabrication of a lightweight biomass-derived carbon aerogel (CKA) with a highly porous structure and superior light absorption, prepared via controlled carbonization process using natural kapok fibers (KF) with sodium silicate as the structural binder. The resultant CKA was employed as the encapsulation of myristic acid-palmitic acid (MA-PA) binary PCM by a vacuum impregnation method. The obtained CKA/MA-PA composite PCMs (CMPPs) exhibit excellent form stability, enhanced thermal properties, and high energy storage density. These results show that the unique three-dimensional network structure of CKA enables a high PCM loading ratio (> 80%) and outstanding thermal cycling reliability. The carbonized structure forms continuous heat conduction pathways, yielding a thermal conductivity of 1.676 W m−1 K−1, which is 3.37 times higher than that of the noncarbonized samples (KMPP). Moreover, CMPPs demonstrate a high enthalpy of phase change (165.7–166.2 J/g) and significantly improved photo/electro-to-thermal conversion performance. The design offers a novel biomass-carbonization-based strategy for developing high-performance composite PCMs, which show great potential for applications in solar energy storage and building energy efficiency.\u0000 </div>","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145846067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As EV adoption accelerates, their charging demand, particularly under Grid-to-Vehicle (G2V) operations, significantly alters the system's load profile. A Time-of-Use (TOU) tariff plan is used to alleviate the problems caused by peak demand and decrease the peak-to-valley load differential, promoting more balanced energy consumption patterns. To enable bidirectional power flow in Vehicle-to-Grid (V2G) applications, to enable energy exchange between EVs and the grid, certain chargers are needed, thereby providing economic incentives to users. In this work, a comprehensive bidirectional EV charging model is developed using the MATLAB/Simulink platform. The model comprises a DC-DC bidirectional converter, an AC-DC front-end, and an LCL filter, all configured for a Level 2 charger that supports a 32A bidirectional current. The Proportional-Integral (PI) controller, on which the control strategy is based, has its settings improved by a Genetic Algorithm (GA) to improve system performance. An evaluation of previous research informs the TOU tariff structure used for cost analysis.

The combination of CQDs and Y2O3 within the conductive PPY matrix resulted in a synergistic enhancement of electrochemical properties, featuring excellent electrical conductivity, numerous redox-active sites, and superior structural stability. Among all formulations, the 0.4 PCY(PPY, sulphonated CQDs, and Y2O3) composite demonstrated the highest specific capacitance of 894.3 F/g at a rate of 2 mV/s, surpassing pure PPY (493.3 F/g), CQDs (128.2 F/g), and Y2O3 (398.2 F/g). This significant enhancement is attributed to the optimized charge transfer pathways facilitated by CQDs and the strong pseudocapacitive effect of Y2O3, which promote efficient ion diffusion and electron transport. Galvanostatic charge–discharge tests further validated the exceptional performance of 0.4 PCY, which achieved a specific capacitance of 860.16 F/g at 1 A/g, maintaining 42% (361.79 F/g) even at 5 A/g. The electrode reached an impressive energy density of 119.4 Wh/kg and a corresponding power density of 2022.5 W/kg, exhibiting remarkable cycling stability with 98.1% capacitance retention after 10 000 cycles. These findings illustrate the high reversibility and durability of the composite.

However, its low thermal conductivity (about 0.2 W/m·K) and phase segregation significantly limit its practical application. While nanofillers and carbon additives can enhance conductivity, they often reduce latent heat, increase costs, and complicate processing. This study introduces a novel, sustainable solution by valorizing Algerian slack wax, a local petroleum refinery byproduct, as a multifunctional enhancer for paraffin. Composites with 6, 10, 15, and 20 mass% slack wax were formulated and characterized using the T-history method. The results demonstrate a breakthrough in simultaneous property enhancement, overcoming typical trade-offs. The 20% composite achieved a 35.65% increase in latent heat (from 106.93 to 145.06 kJ/kg), a 30.48% rise in specific heat (from 3.51 to 4.58 kJ/kg·K), and a 33% improvement in thermal conductivity (from 0.18 to 0.24 W/m·K in the solid state). Furthermore, the material's thermal responsiveness was enhanced, with a 25% reduction in solidification time (from 165 to 120 s) and a 20% faster melting rate (from 125 to 100 s). These improvements are attributed to molecular interactions that disrupt paraffin's crystalline order, facilitating more efficient phonon transport and energy distribution.
