As more charging stations are built, it also becomes critical to ensure that the waiting time before charging is reduced. Reducing waiting times will be crucial in promoting EV adoption. The majority of individuals prefer using electric two-wheelers, such as electric bikes (e-bikes). The e-bikes use low-voltage batteries, which need low power. Therefore, it is crucial to implement chargers that are suited to charge low-voltage, low-power EVs. This study proposes a single-input multi-output (SIMO) modified SEPIC-Ćuk Combined Isolated DC-DC Converter for charging low- and medium-voltage batteries with varying power levels. The modes of operation are described in detail with the pertinent dynamic equations. The non-ideal modeling of the proposed converter parts is detailed. Calculations of the currents and voltages of the components are provided after presenting the converter design for the considered specifications. A detailed design of the high-frequency transformer is provided with the corresponding design equations. The criteria for the selection of components are described, along with the importance of testing the transformer frequency range. Simulation results are provided to validate the calculations, and the converter hardware prototype is implemented to validate the operation and novelty. The high frequency of MOSFET switching ensures a reduced size of inductors and capacitors, leading to a reduced converter size. The proposed converter is a novel isolated DC-DC converter that can be used to charge three EV batteries of different voltage levels simultaneously for low- and medium-power EV applications.\u0000 </div>","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":"7 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143944517","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}

Beyond widely used Li-ion batteries and Pumped Hydro Energy Storage (PHES), Advanced Adiabatic Compressed Air Energy Storage (A-CAES) offers promising potential, although it is not yet commercially available in Europe. This study evaluates the environmental impacts and exergy demand of daily electricity discharge over 30 years for both 10 and 100 MWe A-CAES systems. The 10 MW system is compared to Li-ion batteries (NMC/Graphite, LFP/Graphite, and NMC/LTO chemistries), while the 100 MW system is compared to PHES. Analyses are conducted at both endpoint (human health, ecosystems, and resources) and midpoint levels (climate change and exergy demand). Results show that the 10 and 100 MW A-CAES systems have similar or higher impacts compared to their counterparts when coupled with the French electricity grid mix. This is primarily due to the impacts associated with the electricity to be stored and round-trip efficiency losses: Li-ion batteries and the PHES system have higher efficiency (79.1% and 82%, respectively) than A-CAES systems (54.4% for the 10 MW and 70% for the 100 MW). However, when coupled with renewable sources, which have lower impacts than the French grid mix, A-CAES systems are more beneficial due to lower equipment life cycle impacts, particularly for the 10 MW A-CAES (equipment impact: 11 gCO2eq/kWh returned to the grid) compared to Li-ion batteries (equipment impact: 54 gCO2eq/kWh returned to the grid). The study highlights A-CAES as a viable long-term storage alternative within a cradle-to-grave framework, though it acknowledges limitations, such as differences in technology readiness level (TRL) and the need for measured data to strengthen comparisons with established solutions.","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":"7 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/est2.70194","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143944650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microwave heating is an efficient and green method of heating. It is a facile and mild heating method through which uniform and synchronized heating can be done. Thus, it helps in enhancing the uniform porosity throughout the graphene matrix. The optical, structural, and thermal characterization of synthesized RGO and after microwave heat treatment (MWRGO) have been done using UV–Visible absorption spectroscopy, Transmission Electron Microscopy (TEM), Fourier Transform Infrared (FTIR) spectroscopy, Raman spectroscopy, and Thermogravimetric Analysis (TGA). The prepared materials were tested for supercapacitor (SC) in a symmetric electric double layer capacitor (EDLC) type parallel plate cell design. The prepared cell has been checked for electrochemical performance using cyclic voltammetry (CV) measurements and cross-confirmed through Electrochemical Impedance spectroscopy (EIS) and Galvanostatic Charge–discharge (GCD) measurements. Enhanced electrochemical performance of MWRGO-based supercapacitive cell depicts specific capacitance of 289 F/g at low ESR of 3.4 Ω and energy density of 24 Wh/Kg at power density of 1000 W/Kg. This is due to enhanced specific surface area to 731.81 m2/g after microwave heat treatment, which hence plays a major role in achieving virtuous electrochemical performance of RGO for energy applications.\u0000 </div>","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":"7 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143944688","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}

To improve the performance of BTMS, the bare batteries with different extended surfaces (straight and arc) are considered to enhance the dissipation of heat, leading to significant enhancement of bare battery performance. In the present study, numerical simulations are carried out to study the impact of extended surfaces and the influence of CuO (10%) nano additive dispersion in PCM. Also, analyses are carried out by modifying the geometries of the arc fins to enhance the thermal performance of the battery. Results reported that the proposed extended surfaces improved the battery life by 61%–90% compared to conventional BTMS systems. Extended surfaces boost heat exchange surface area, improve battery-to-PCM/CuO heat dissipation, and form a novel method for heat conduction during liquid fraction melting. This network expands by increasing arc fin radial distance, enhancing thermal performance. At ambient temperature range of 15°C–45°C, the PCM/CuO/fin system substantially improved compared with the PCM-based system by 163%, 192%, and 212%, respectively. These findings demonstrate the possibility of straight and arc fin shapes to improve PCM battery thermal control. The experimental and numerical results show how these fin designs optimize heat transport, increasing battery life and improving thermal control under varied operating situations. This novel approach overcomes PCM-based system restrictions to improve battery performance and lifetime.\u0000 </div>","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":"7 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143939201","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}

Structural authentication revealed that CNPs act as suitable spacers, isolating the 3D GO network layers up to 3.8 sheets (single-sheet thickness: ~0.55 nm). The as-prepared nanocomposites, characterized under a three-electrode electrochemical system in aqueous solution (1 M KOH), displayed high electrochemical capacitive charge storage (97% at scan rate of 100 mV s−1), very high specific capacitance (250 F g−1 at 0.25 A g−1 and 277 F g−1 at 50 mV s−1), and excellent cyclic retention (85.6% of the initial capacitance after 10 000 cycles). A GO-sheet/CNP-based symmetric supercapacitor device delivered excellent specific energy-power density of 64.8 W h kg−1 and 1372.2 W kg−1, respectively. Consequently, the device could power a white-emitting LED of 10 W at 2.5 V for 1 min with full brightness against a charging time of 20 s.

To enhance their H2 molecule adsorption properties, Y atoms are decorated on the COFs with an average binding energy of about 5–6 eV per Y atom. Each Y atom of Y-decorated COFs, YCOF1, YCOF2, and YCOF3 effectively adsorbs six H2 molecules with an average H2 adsorption energy of −0.28, −0.34, and −0.35 eV per H2 molecule, respectively.
