Vanadium redox flow batteries (VRFBs) have emerged as a viable solution for large-scale energy storage, valued for their high efficiency, safety, scalability, design flexibility, and long operational lifespan. The proton exchange membrane (PEM) is a pivotal component in VRFBs, exerting a profound influence on battery efficiency and economic viability. Sulfonated poly(ether ether ketone) (SPEEK) membranes have garnered considerable attention as promising PEM candidates for VRFBs, due to their simple structure, straightforward synthesis, superior thermal and mechanical stability, cost-effectiveness, and amenability for modification. However, the large-scale application of SPEEK membranes in VRFBs is impeded by the inherent tradeoff between proton conductivity and vanadium ions permeability. The degree of sulfonation in SPEEK membranes is a critical parameter influencing their performance, as increased sulfonation improves proton conductivity but also augments ions permeability and membrane swelling simultaneously, compromising both membrane and battery performance. Addressing these limitations requires innovative strategies, such as structural regulation, functionalization, surface modification, and composite structure to enhance SPEEK membrane performance. In this review, we examine the recent research progress in the development of SPEEK membranes for VRFBs, encompassing recent advancements in optimizing their structure-performance relationship and chemical stability. The review culminates with a critical evaluation of the challenges and potential future research directions for advancing the development of SPEEK membranes for VRFB applications.

Thermal performance of lithium-ion battery tabs under liquid immersion cooling conditions

Future Batteries

Pub Date : 2025-02-01 DOI: 10.1016/j.fub.2025.100037

The thermal performance of the electrode terminals or tabs of a 26650 LiFePO₄ cylindrical lithium-ion battery under direct contact liquid immersion cooling conditions is experimentally investigated during charging and discharging, highlighting their contribution to the overall heat transfer from the battery which has not been examined previously. High rates of heat transfer occur from the terminal surfaces for complete immersion in Novec 7000 due to the battery’s anisotropic thermophysical properties, coupled with additional heating from the electrical connections. The establishment of two-phase conditions for initial bulk fluid temperatures of 33 °C ± 0.5 °C further augments the heat transfer, providing greater thermal uniformity across the entire battery as nucleate boiling is induced on the terminal surfaces. Vigorous vapour bubble growth and departure limits the temperature difference between the terminals and the bulk fluid, indicative of the heat transfer intensity, with values two to three times lower than those observed under natural convection liquid immersion conditions. For the discharge rate of 10C, the phase change restricts the temperature difference between the positive and negative terminals and the bulk fluid to a maximum of 3.5 °C and 5 °C respectively. A corresponding cell thermal inhomogeneity of 2.2 °C is maintained, minimising accelerated electrochemical material degradation. Similar performance is exhibited during charging at the rate of 4C, restricting the temperature difference between the positive and negative terminals and the bulk fluid to a maximum of 1.4 °C and 2.2 °C respectively, and the cell thermal inhomogeneity to 1 °C.

The rapid expansion of the electric vehicle (EV) market has necessitated the use of high-performance battery packs, predominantly lithium-ion batteries (LIBs). Their implementation in devices and adaptation to specific applications can profit of computational models able to predict their functional behaviour and aging. However, the advancement of LIBs is constrained by the chemical and electrochemical limits of their materials, leading to interest in lithium metal batteries (LMBs) due to lithium's superior theoretical specific capacity and redox potential. Despite the potential advantages of LMBs, challenges such as uneven metal deposition leading to continuous side reaction with the electrolyte, active material loss through formation of dead Li, dendrite formation and safety issues hinder their practical application. These critical points limited the developments of reliable predictive models to outline in silico the functional properties of LMBs and aging. This study aims to develop a computational tool to monitor the state-of-health (SOH) of LMBs and predict capacity fading. A D-optimal experimental design approach was employed to systematically investigate the effects of various aging factors, including state of charge (SOC), C-rate, rest time, and depth of discharge (DoD) on LMB performance by selecting 18 compatible experimental cycling conditions. Starting from this dataset a regression framework was utilized to model the SOH, providing key insights into the aging mechanisms. The results indicate that while overall capacity loss correlates with the selected variables, the specific impact on open-circuit voltage changes was less pronounced. This study highlights the effectiveness of combining experimental design and chemometric analysis to enhance our understanding of LMB aging, thereby paving the way for improved battery health monitoring and management strategies.

Titanium(IV) oxide (TiO₂) is a promising alternative to graphite anodes used in Li-ion batteries (LIBs) due to its low toxicity and small volume change during cycling. SnO₂ has a higher specific capacity than TiO₂ but suffers from large volume changes during charging-discharging. Accordingly, doping of TiO₂ with Sn can provide higher Li-ion storage capacity, while maintaining the advantages of TiO₂. Here, a mesoporous Sn-doped TiO₂ with high surface area (up to 259 m²/g) is synthesized using an inverse micelle sol-gel method followed by varying the calcination temperature. Crystallographic studies showed successful Sn doping. The electrochemical performance of the synthesized materials was evaluated by constructing a lithium-ion half-cell battery and all the batteries were cycled at both constant and variable charge rates. The 8 % Sn doped TiO₂ calcined at 350℃ had the highest 340 mAh/g specific capacity which is twice that of the same amount of Sn-doped sample calcined at 250℃. There is a correlation between increased Li-ion storage capacity of the calcined mesoporous samples and the porosity and oxidation state of the constituent ions. The intent of this study is to show the importance of optimizing calcination temperature that may result in improved electrochemical performance of Li-ion batteries with similar anode materials, not necessarily to outperform the existing Sn-doped TiO₂ samples.

Charging strategy optimization using a dynamic programming and physics-based model for fast and safe battery charging at low temperatures

Although fast-charging technology for lithium-ion batteries is being developed for the continued commercialization of electric vehicles (EVs), fast charging at low temperatures can substantially shorten battery life and cause fires. Therefore, it is crucial to develop a technology that can balance the trade-off relationship between battery degradation and reduced charging time. This research offers a model-based optimization methodology for charging strategies to control the battery-charging time and lithium plating at low temperatures. A dynamic programming algorithm that guarantees a global optimum is used as an optimization method. To formulate the optimization problem for dynamic programming (DP), the electrochemical model of the battery was converted to a control-oriented model with model reduction methods. To overcome the high computational burden of DP, we developed a good fidelity model including single-particle model with electrolyte (SPMe), thermal model, and plating model with a small number of states. The conscious factor was defined as a weighting factor between the two costs of charging time and lithium plating thickness, and the algorithm was performed at various conscious factors and ambient temperature conditions. The optimization result was verified by simulating the optimized charging profile of the algorithm using a full electrochemical model. The final result was analyzed and discussed using Pareto frontier and sensitivity analysis. In all the optimizations performed, a cost reduction of at least 7 % and up to 57 % was achieved compared to conventional 1C-rate constant-current-constant-voltage (CCCV) charging strategy. This result indicates that the proposed charging strategy offers an effective optimization method that can easily handle the trade-off between degradation and charging time to achieve fast and safe charging under low-temperature conditions.

The facile synthesis of binder-free electrodes for supercapacitors is crucial, as it provides high electrochemical performance, excellent conductivity, easy manufacturing, and enhanced cycling stability. Layered double hydroxides (LDH) and layered triple hydroxides (LTH) are excellent candidates for achieving these storage characteristics. In this work, binder-free CoNi LDH/nickel foam (NF), CoMn LDH/NF, NiMn LDH/NF, and CoNiMn LTH/NF electrodes were prepared using a facile one-step hydrothermal method. Various characterization techniques were employed to investigate and compare the structural, microstructural, and electrochemical properties. The CoNiMn LTH/NF electrode demonstrated the highest specific capacitance of 2212 F g⁻¹ , attributed to its unique 1D nanoneedle morphology and the synergistic effect of Co, Ni, and Mn elements. The nanoneedle morphology of CoNiMn LTH/NF results in additional diffusion channels and facilitates the penetration of electrolytes. Moreover, the CoNiMn LTH/NF//activated carbon capacitor exhibited battery-type behavior with an energy density of 26.4 Wh kg⁻¹ at a power density of 1397 W kg⁻¹ .

Aluminum rechargeable batteries were prepared using commercially available iron oxide powder or reduced graphene oxide modified with iron oxide nanoparticles as positive electrode materials. The commercially available iron oxide powder was reversibly charged/discharged, but its capacity was very small, whitlow 15 mA h g⁻¹. The charge/discharge mechanism was investigated by using X-ray diffraction, and it was found that iron oxide was reduced to iron metal during discharge, indicating a conversion-type reaction. This is the first time that a conversion-type positive electrode material for aluminum rechargeable batteries has been constructed using iron oxide. By utilizing a sulfone base electrolyte, we have fabricated the aluminum rechargeable batteries using a conversion reaction with copper chloride. A similar effect is expected for iron oxide. The use of reduced graphene oxide modified with iron oxide nanoparticles as a positive electrode resulted in a significant increase to 100 mA h g⁻¹ in charge/discharge capacity, and the capacity retention after 100 cycles was about 60 %, showing good cycle characteristics for a rechargeable battery as a conversion-type electrode material.

The use of reduced graphene oxide modified with iron oxide nanoparticles as a positive electrode resulted in a significant increase to 100 mA h g<sup>−1</sup> in charge/discharge capacity, and the capacity retention after 100 cycles was about 60 %, showing good cycle characteristics for a rechargeable battery as a conversion-type electrode material.</div></div>","PeriodicalId":100560,"journal":{"name":"Future Batteries","volume":"5 ","pages":"Article 100030"},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143131389","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}

This paper presents a comprehensive survey on data-driven online estimation of state of health (SoH) for alternative battery chemistries for maritime applications, with a particular focus on LFP lithium-ion and sodium-ion types of batteries. In addition, the emerging concept of state of safety (SoS), a critical yet underexplored metric for maritime battery systems, is explored. Building on previous work on nickel–manganese–cobalt (NMC) lithium-ion batteries, this study evaluates the applicability of existing SoH estimation methodologies to alternative chemistries. The findings suggest that similar data-driven approaches, including empirical and semi-empirical methods, physics-based models, machine learning models, and hybrid approaches, can be employed across these chemistries. However, the methods require calibration, fine-tuning, and validation for each specific battery type. It is believed that SoS holds significant potential for maritime applications, provided it incorporates a relevant set of safety sub-functions with properly defined thresholds and warning criteria. Its integration into real-time monitoring systems appears feasible, given continuous measurement of relevant inputs. However, further research is recommended on how to best account for interdependencies between the various safety sub-function and correlations in the input data as well as how to account for the effect of degradation on SoS. Additionally, it seems reasonable to investigate whether some kind of memory could be incorporated in order to account for the experience of previous abusive conditions.

Nanocarbon composites have emerged as a vanguard technology in energy conversion and storage, redefining the paradigms of battery, supercapacitor, and solar cell design. Researchers are orchestrating a paradigm shift in energy storage dynamics by leveraging the exceptional characteristics of materials such as graphite, fullerene, graphene, and carbon nanotubes. The intrinsic attributes of nanocarbon, including superior electrical conductivity, mechanical resilience, and expansive surface areas, delineate them as pivotal constituents for augmenting the performance metrics of energy storage and conversion devices. In the domain of batteries, nanocarbon composites engender heightened energy density, accelerated charge/discharge kinetics, and prolonged cycle life. Concurrently, their integration into supercapacitors begets augmented energy and power densities, facilitating swift energy transference and storage. These composites' malleable and lightweight nature introduces a transformative dimension, enabling the fabrication of compact, pliable, and highly efficient energy storage apparatus.
