However, its practical application is hindered by severe structural instability arising from large volume changes during cycling. Drawing inspiration from conversion/alloying-based anode design strategies, hierarchical micro/nano-structured Bi/ZnO@C composites is developed to mitigate rapid capacity fading and enhance electrochemical performance. The optimized Bi/ZnO@C anode exhibits outstanding reversibility and cycling stability, delivering high gravimetric and volumetric capacities of 797 mAh g⁻¹ and 1546 mAh cm⁻³, respectively, after 180 cycles at 0.1 A g⁻¹, and retaining 379 mAh g⁻¹ after 1000 cycles at 1.0 A g⁻¹—surpassing the performance of conventional Bi-based anodes. Furthermore, a full-cell configuration paired with a LiCoO₂ cathode achieves a high energy density of 829 Wh L⁻¹. This exceptional performance is attributed to the uniform dispersion of Bi and ZnO nanoparticles within a carbon microsphere matrix, which forms beneficial heterointerfaces and defect structures. These features effectively accommodate (de)lithiation-induced stress, preserve continuous ion/electron transport pathways, and promote rapid ion and charge transfer. Ex situ characterizations combined with density functional theory (DFT) simulations confirm enhanced Li⁺ adsorption capability, accelerated reaction kinetics, reduced charge-transfer resistance, and improved structural integrity of the Bi/ZnO@C electrode.</div></div>","PeriodicalId":15942,"journal":{"name":"Journal of energy storage","volume":"128 ","pages":"Article 117039"},"PeriodicalIF":8.9,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144169385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study proposes a hybrid fuzzy linear programming based energy management strategy considering adaptive multi-linear membership functions of fuzzy models. The fuzzy models are established for the grid’s power outputs, Photovoltaic power, load power, the power grid’s cost, and both power and energy of the involved batteries into the microgrids. The multi-linear membership functions emulate the objectives’ physical characteristics and operational constraints. Additionally, with the objective function of the minimum power’s cost, the parameters of membership functions are optimized by the Tunicate Swarm algorithm. Two realistic microgrid applications from Bangladesh and South France are employed to prove the efficiency and accuracy of the proposed strategy under different climate changes, which are divided into two cases for clear and cloudy days. The implementation of the proposed methodology is carried out using SimScape/Matlab software. Compared to the conventional methods, the simulation results demonstrate that the proposed strategy leads to more economical energy management with significant savings of up to 14%–27%, and enhances the battery’s lifetime as the number of charging/discharging per clear/cloudy day compared to the heuristic method. Therefore, the proposed strategy can effectively provide a generic energy management strategy under important uncertainty and climate changes.</div></div>","PeriodicalId":15942,"journal":{"name":"Journal of energy storage","volume":"128 ","pages":"Article 116977"},"PeriodicalIF":8.9,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144169390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During engineering design, the laminar mixed convection often occurs in high-heat-flux tubes, thereby altering the flow and heat transfer characteristics. However, the use of traditional correlations in the design of thermal energy storage system can lead to substantial errors. To address this issue, the laminar mixed convection of molten salt in horizontal tubes under the non-uniform heat flux condition is investigated. Furthermore, the effects of tube diameter, inlet temperature, and heat flux are analyzed. Results showed that increasing heat flux and tube diameter boosts Nusselt number and thermal entropy production rate, yet reduces flow entropy production rate and exergy efficiency. Increasing heat flux and decreasing tube diameter decreases friction factor. Increasing inlet temperature decreases friction factor, flow and thermal entropy production rates, but increases exergy efficiency. Compared to forced convection, the friction factor, Nusselt number, flow entropy production rate and exergy efficiency increases by 47.03 %, 114.43 %, 62.90 %, 21.06 % at most for mixed convection under non-uniform heat flux conditions, respectively. However, the thermal entropy production declines by up to 51.82 %. By increasing heat flux, inlet temperature and tube diameter, the location, at where the buoyancy force takes effect, decreases. Finally, a new friction factor correlation with 3.75 % uncertainty and Nusselt number correlation with 15.00 % uncertainty are proposed. The investigation finding will not only help improve the design of thermal energy storage systems, but also will help to optimize heat transfer, minimize energy loss and improve safety.</div></div>","PeriodicalId":15942,"journal":{"name":"Journal of energy storage","volume":"128 ","pages":"Article 117218"},"PeriodicalIF":8.9,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144169386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared with the existing STD algorithm, the proposed improved spatiotemporal decomposition (ISTD) algorithm extends the piecewise approximate value function from the linear form to the quadratic form, which helps to describe the nonlinear characteristics among different decomposed subproblems. Different from the existing STD algorithms, which needs to call commercial solvers repeatedly to solve a number of subproblems, the proposed ISTD algorithm directly obtains their closed-form solutions according to the algebraic expressions.
