The present investigation aims to synthesize a novel (AlCuCoFeMnNi)₃O₄ type high entropy spinel oxide through the sol-gel and investigate the effect of different carbon-based additives on charge storage performance. The formation of the inverse spinel phase of [B(AB)O₄] type inverse spinel phase was confirmed through the detailed x-ray diffraction analysis of the synthesized sample. The synthesized spinel phase was indexed with the space group of Fd−3m and has a lattice parameter of 8.2697 Å. The synthesized high entropy oxide (HEO) phase Ni, Co, and Fe coexists in +2 and +3 states. At the same time, Cu in +2 state, Al in +3 state, and Mn in +3 and +4 states confirmed through x-ray photoelectron spectroscopy. The electrochemical charge storage performance of synthesized HEO was measured through the three-electrode setup in 2 M KOH aqueous electrolyte solution in two different potential windows, such as −0.2 to 0.4 V and 0.0 to 0.5 V. Different carbon-based conducting materials such as acetylene black, reduced graphene oxide (RGO), and carbon particles obtained from 10-hour ball-milling of used dry cell carbon electrode (CP). The charge storage mechanism changes from electrochemical double layer capacitance to pseudocapacitive type as the potential window varies from −0.2 to 0.4 to 0 to 0.5 V. The value of specific capacitance for an electrode made of HEO with acetylene black, RGO, and CP was found to be 32.67, 7.50, and 4.58 F/g and 30.68, 16.33, and 9.05 F/g in the potential window of −0.2 to 0.4 V and 0 to 0.5 V at a scan rate of 5 mV/s, respectively. The cyclic performance of the developed three electrodes was measured at a scan rate of 100 mV/s for 1000 cycles, and it was found to be 94%, 98%, and 99% for electrodes made of HEO with acetylene black, RGO, and CP, respectively.

The present study employs rigorous DFT analysis using WIEN2k for the best suitability of the Cr₂O₃ as an electron transport layer, synergetic with nontoxic and thermally stable CsSnCl₃ perovskite solar energy storage device, configured as FTO/Cr₂O₃/CsSnCl₃/CBTS/Au. The main objective of our investigation is to improve the device performance by optimizing thickness, carrier concentration, bulk defect density of each layer, interface defects, operating temperature, as well as the impact of parasitic elements on device performance. SCAPS-1D tool was used to optimize the novel device architecture. The simulation results reveal that a CsSnCl₃ layer with an optimized thickness of 800 nm and a doping concentration of 1 × 10¹⁵ cm⁻³ yields noteworthy outcomes, specifically, champion efficiency (𝜂) of 22.01% along with an open-circuit voltage (V_oc) of 1.12 V, a short-circuit current (J_sc) of 23.86 mA/cm², and a fill factor of 81.65%. These improved findings were compared with existing theoretical and experimental reported data and found to exhibit the best performance. The present research substantially enhances the understanding of eco-friendly CsSnCl₃ perovskite solar cell optimization, thereby extending its applicability to future photovoltaic and optoelectronic devices.

In terms of electric vehicle architectures, the drivetrain offers unprecedented freedom, but it also creates new obstacles in terms of achieving all needs. The architecture of electric vehicles is simplified and adjustable at the component level because they don't have a combustion engine or fuel tank, only an electric motor and a battery. Implementing safe zones within electric vehicles (EVs) to accommodate battery packs necessitates significant adjustments to ensure the secure integration of the battery. A Battery EV, also known as a pure EV, solely relies on rechargeable battery packs as its source of energy, without any additional propulsion system. The Battery Management System (BMS) plays a significant role in maintaining the safety of electric vehicles by controlling the electronics of rechargeable batteries, whether they are individual cells or battery packs. The BMS plays crucial role in protecting both the user and the battery by monitoring and maintaining the cell's operation within safe limits. This research paper focuses on the control of solar-powered charging for lithium-ion batteries. An optimized FOPID controller is utilized to maximize power extraction from PV array and efficiently charge the battery. A hybrid optimization model is employed to optimize the gain parameters of the FOPID controller.

In order to achieve the “carbon peaking and carbon neutrality” goals, we must vigorously develop renewable energy power generation. As the penetration of renewables progressively escalates, the corresponding demand for battery energy storage systems (BESS) within the power grid rises concomitantly. This paper presents an innovative optimization approach for configuring BESS, taking into account the incremental variations in renewable energy penetration levels and BESS charge-discharge cycles. Employing incremental analytical techniques and pivotal metrics such as capacity elasticity, the proposed method determines the optimal penetration rate and corresponding BESS capacity outcomes for deploying energy storage systems. An example analysis of a rural power distribution benchmark is carried out by using the method in this paper, which proves the effectiveness of the method in this paper. This methodology was substantiated through its application to a case study of a rural power distribution benchmark, thereby validating its efficacy. Furthermore, it was compared with the particle swarm optimization, providing a comparative assessment of their relative performance.

The current study is focused on the development of phase change material composites (PCCs), attained by the solvent-casting method, comprising a hydrophilic polymer matrix (polyvinyl alcohol) enclosing polyethylene glycol (PEG600) as an active thermal energy storage (TES) component, and anchored with titanium dioxide nanoparticles (TDN). The impact of the integrated metal oxide nanoparticles at different loadings (0.25%-1%) on the TES attributes, thermal stability, UV resistance, and flame retardancy of the fabricated composites has been studied. The Fourier-transform infrared and field-emission scanning electron microscopy techniques have been used to characterize the PCCs obtained. Phase change attributes and thermal stability of the resultant PCCs are evaluated by differential scanning calorimetry (DSC) and thermogravimatric analysis (TGA). The introduction of TDN particles in different concentrations to the PCCs considerably refines the phase change variables and thermal resistance of the reinforced film samples. PCCs film with 1% TDN concentration exhibited onset melting and crystallization temperatures at −9.9°C and 13.5°C, respectively, and peak melting and crystallization transitions occurred at 8.7°C and 3.6°C, with associated heat enthalpies of 25.57 and 22.22 J g⁻¹, respectively. UV and flame-retardant (FR) features of the PCCs were found to be improved with the presence of metal oxide particles in the composite films. The metal oxide nanoparticles enhance the FR behavior of fabricated composites by 11.45% as compared to unfilled films.

Generation of green energy is critical for addressing the environmental pollution and saving aquatic life in future by reducing the greenhouse gas. Green energy is generated using sources like wind, water, sun, living plants, and so on. These sources are essential for long-term efforts to mitigate climate change. The large-scale use of green energies will contribute to sustainable development which ensure access to reliable, and chemical free energy to power up the portable devices. This research article proposes design of green rechargeable and regenerative battery for brighter future. The proposed battery is not only rechargeable and eco-friendly but also non-flammable and can survive at extreme weather conditions T = 70°C (V = 1.52 V, I = 75.5 μA) and T = −65°C (V = 1.52 V, I = 55.2 μA). The electric current of the designed battery also depends on shaking/rotation. The proposed battery can charge 80% to 90% of its initial value within 30 to 40 minutes which makes it a favorable candidate where faster recharging is needed. The designed battery does not show any heating effect even at T = 70°C. Since, battery is free from any chemical, it is therefore does not release any hazardous chemicals once dispose of.

Phase change materials (PCMs) can absorb, store, and release substantial latent heat within a specific temperature range during phase transition and have gained huge attention due to environmental concerns and energy crises. However, PCMs have a significant downside in energy storage due to their relatively lower thermal conductivity, leading to inadequate heat transfer (HT) performance. The foremost aim of the research is to synthesize an eco-friendly coconut shell biochar (CSB) dispersed with organic A46 PCM in the temperature range of 44°C to 46°C to form a green nanocomposite. A two-step approach is adopted to formulate the nanocomposites with different weight concentrations (0.2% and 0.8%) of green CSB particles. The developed nanocomposite's thermal conductivity and chemical stability were examined using a thermal properties analyzer and a Fourier transforms infrared spectrometer. The developed biochar composites have excellent thermal conductivity (0.39 W/m K) compared with base PCM (0.22 W/m K). Also, the developed nanocomposites were physically mixed together; there were no additional functional groups formed compared to pristine PCM, and the prepared materials were composite. Furthermore, a numerical analysis was performed using two-dimensional energy modeling software to ascertain the HT rate of A46 composites. These thermally energized green nanocomposites show great promise for thermal energy storage and thermal management applications like battery thermal management, photovoltaic thermal systems, desalination systems, electronic cooling, building applications, and textiles.

Extreme climate events are on the rise, posing significant challenges to power systems, leading to blackouts and infrastructure damage. Energy storage plays a crucial role in enhancing grid resilience by providing stability, backup power, load shifting capabilities, and voltage regulation. While stationary energy storage has been widely adopted, there is growing interest in vehicle-mounted mobile energy storage due to its mobility and flexibility. This article proposes an integrated approach that combines stationary and vehicle-mounted mobile energy storage to optimize power system safety and stability under the conditions of limiting the total investment in both types of energy storages. The principal aim is to minimize the weighted energy not served index in the presence of fault conditions. By strategically allocating energy storage resources and dynamically dispatching stored energy, operators can ensure rapid response and effective power restoration, improving overall reliability in the face of extreme weather events.
