Abstract Lithium manganese silicate (Li-Mn-Si-O) cathodes are key components of lithium-ion batteries, and their physical and mechanical properties are strongly influenced by their underlying crystal structures. In this study, a range of machine learning (ML) algorithms were developed and compared to predict the crystal systems of Li-Mn-Si-O cathode materials using density functional theory (DFT) data obtained from the Materials Project database. The dataset comprised 211 compositions characterized by key descriptors, including formation energy, energy above the hull, bandgap, atomic site number, density, and unit cell volume. These features were utilized to classify the materials into monoclinic… More >

Abstract Self-assembled highly hierarchical novel SnS₂ microflowers having acute edge nanopetals have been fabricated using a facile template-free hydrothermal growth technique utilizing Tin (II) chloride dihydrate (SnCl₂·2H₂O) and Sodium sulfide nonahydrate (Na₂S·9H₂O) as reaction reagents. Morphological analysis exhibits the flower-type SnS₂ microarchitectures ranging from 4 to 7 μm. The vibrational mode measured at A_1g = 314 cm⁻¹ confirms the existence of hexagonal phase SnS₂ using Raman spectroscopy. The electrochemical results suggest the promise of as-synthesized SnS₂ structures as a cathodic material in lithium-sulfur batteries. More >

Abstract The pursuit of safer energy storage systems is driving the development of advanced electrolytes for lithium-ion batteries. Traditional liquid electrolytes pose flammability risks, while solid-state alternatives often suffer from low ionic conductivity. Gel polymer electrolytes (GPEs) emerge as a promising compromise, combining the safety of solids with the ionic conductivity of liquids. Cellulose, an abundant and eco-friendly polymer, presents an ideal base material for sustainable GPEs due to its biocompatibility and mechanical strength. This study systematically investigates how drying methods affect cellulose-based GPEs. Cellulose hydrogels were synthesized through dissolution-crosslinking and processed using vacuum drying (VD),… More >

Abstract Biomass-derived hard carbon has gradually become an important component of sodium-ion batteries’ anodes. In this work, Setaria viridis, a widely distributed plant, was employed as a precursor to synthesize hard carbon anodes for sodium-ion batteries. However, the hard carbon derived from raw precursors contains substantial impurities, which limit the performance of the obtained hard carbon. With different chemical etching processes, the content of impurities in the resultants was reduced to varying degrees. The optimized hard carbon anode delivered a reversible capacity of 198 mAh g⁻¹ at a current density of 0.04 A g⁻¹. This work shows the More > Graphic Abstract

Abstract Delving alternative high-performance anodes for lithium-ion batteries have always attracted scientist attention. A wide-bandgap semiconductor with excellent mechanical properties, “silicon carbide (SiC)”, has been introduced as the anode electrode. Two-dimensional SiC has special hybridization which can build it as an appropriate substitution for graphene. Energy storage technologies are keys in the extension and function of electric devices. To keep up with steady innovations in saving energy technologies, it is essential to progress corresponding practical strategies. In this research article, SiC has been designed and characterized as an anode electrode for lithium (Li), sodium (Na), beryllium… More > Graphic Abstract

Abstract This study investigates the feasibility of a novel dual two-phase cooling system for thermal management in lithium-ion batteries used in electric vehicles (EVs). The proposed system aims to combine low-boiling dielectric fluid immersion cooling and pulsating heat pipes (PHPs), in order to leverage the advantages of both technologies for efficient heat dissipation in a completely passive configuration. Experimental evaluations conducted under different discharge conditions demonstrate that the system effectively maintains battery temperatures within the optimal range of 20–40°C, with enhanced temperature uniformity and stability. While the PHP exhibited minimal impact at low power, its role More >

Abstract In recent years, ultrathin polymer-based electrolytes (UPEs) have emerged as a promising strategy to enhance the energy density of rechargeable batteries for wearable devices by minimizing electrolyte volume, demonstrating higher ionic conductance and lower internal resistance, and more compact battery stacking compared to conventional thick polymer-based electrolyte. This mini review systematically summarizes recent advances in ultrathin solid-state and gel-state electrolytes, focusing on their preparation strategies, advantages, and disadvantages, where the energy density, interfacial stability, mechanical properties, and ion-transport mechanisms are also analyzed for understanding the UPE application. Moreover, the challenges such as dendrite penetration and More >

Abstract With the rapid development of flexible and wearable electronic devices, the demand for flexible power sources with high energy density and long service life is imminent. Zinc-air batteries have long been regarded as an important development direction in the future due to their high safety, environmental efficiency, abundant reserves and low cost. However, problems such as zinc dendrite growth, corrosion, by-product generation, hydrogen evolution and leakage, and evaporation of electrolyte affect the commercialization of zinc-air batteries. In addition, currently widely used aqueous electrolytes lead to larger batteries, which is not conducive to the development of… More >

Abstract Since lithium-ion batteries have been put into use, the recession of work cycle efficiency at low temperatures has received widespread attention. In this paper, we investigated the effect of low temperature (−5°C, 0°C, 5°C) environments on the performance of lithium-ion batteries, which are well-known for their excellent discharge performance, cycle life, and safety. However, lithium-ion batteries exhibit significant capacity degradation at low temperatures, especially at 0°C, losing availability after only 10 cycles. Therefore, we conducted cycle degradation tests at 1C discharge and 100% charge-discharge conditions. In this paper, we analyzed the surface morphology, structure, and More > Graphic Abstract

Abstract The growing concern for energy efficiency and the increasing deployment of intermittent renewable energies has led to the development of technologies for capturing, storing, and discharging energy. Supercapacitors can be considered where batteries do not meet the requirements. However, supercapacitors in systems with a slower charge/discharge cycle, such as photovoltaic systems (PVS), present other obstacles that make replacing batteries more challenging. An extensive literature review unveils a knowledge gap regarding a methodological comparison of batteries and supercapacitors. In this study, we address the technological feasibility of intermittent renewable energy generation systems, focusing on storage solutions… More > Graphic Abstract
