The challenges of fast charging of LIBs have limitations such as low lithium-ion transport in the bulk and solid electrode/electrolyte interfaces, which are mainly influenced by the ionic conductivity of the electrolyte. Therefore, electrolyte engineering plays a key role in enhancing the fast-charging capability of LIBs. Here, we synthesize a novel propionic acid-based viologen that contains a 4,4′-bipyridinium unit and a terminal carboxylic acid group with positive charges that confine PF6‒ anions and accelerate the migration of lithium ions due to electrostatic repulsion, thus increasing the overall rate capability. The LiFePO4/Li cells with 0.25% of viologen added to the electrolyte show a discharge capacity of 110 mAh g‒1 at 6C with 95% of capacity retention even after 500 cycles. The added viologen not only enhances the electrochemical properties, but also significantly reduces the self-extinguishing time.","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"4 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.20240039","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145012937","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}

Arguably, the best approach to the problem of EOL LIBs is recycling and recovery of the metals contained within the cells. This allows the diversion of the EOL battery cells from the environment and the recovery of precious metals that can be reused in the manufacturing of new products, allowing the reduction of the requirements of virgin materials from the mining industry. The most significant hindrance to the recycling process of EOL LIBs is their unstable chemical nature and significant safety hazards related to opening the air-tight casings. To minimise these issues, the end-of-life cells must be stabilised in one of the few available ways. This review aims at a comprehensive presentation of the studied chemical methods of EOL LIB cell discharge and stabilisation. The advantages and disadvantages of the method and its variations are discussed based on the literature published to date. The literature review found that a significant number of authors make use of chemical stabilisation techniques without proper comprehension of the associated risks. Many authors focus solely on the cheapest and fastest way to stop a cell from producing an electrical charge without extra thought given to the downstream recycling processes of safety hazards related to the proposed stabilisation method. Only a few studies highlighted the risks and problems associated with chemical stabilisation techniques.","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"4 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.20240086","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145012695","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}

However, LSBs have various promising advantages, including an ultrahigh energy density (2600 Wh kg−1), cost-effectiveness, environmental friendliness, low weight, and flexible attributes, which suggest the feasibility of their current and near-future practical applications in fields that require these characteristics, irrespective of their moderate lifespan.

In particular, electric double-layer (EDL) mSCs utilizing flexible graphene electrodes have gained significant attention due to their quick and efficient charge/discharge capabilities. Despite significant progress in fabricating mSCs, particularly through the development of laser-induced graphene (LIG) for creating 3D porous electrodes, challenges remain in increasing both energy and power densities. One promising strategy to address these challenges is the incorporation of pseudo-capacitive materials into the 3D graphene structure. However, conventional methods for embedding pseudo-capacitive materials often involve complex and additional labor-intensive steps to the manufacturing process. In this work, we introduce a high-speed mSC fabrication method (< 5 min) that employs a continuous laser-scribing process to directly integrate Mn2O3, a pseudo-capacitive material, onto LIG electrodes, forming hierarchical Mn2O3/LIG structure. By precisely controlling the fabrication parameter, this approach can significantly improve the electrochemical performance by optimizing the density and thickness of Mn2O3, leading to 550.5% increase in capacitance and energy density compared to the LIG electrode. Additionally, the mSCs exhibit outstanding cyclic (> 88% @ 20,000 cycles) and mechanical stability (@ bending radius of 5 mm), confirming their potential for seamless integration into electronic circuits. This innovation not only simplifies the production process of high-performance mSCs but also broadens their potential applications in sustainable and compact electronic device system.","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"4 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.20240079","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145013101","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}

Herein, to improve the low-temperature tolerance, a localized high-concentration electrolyte based on weak solvation (Wb-LHCE) has been designed by adding a diluent hexafluorobenzene (FB) in a weak solvating solvent tetrahydrofuran (THF). Combining theoretical calculations with characterization tests, it is found that with the addition of diluent FB, the dipole–dipole interaction between the diluent and the solvent causes FB to compete with Li+ for THF. This competition causes the solvent to move away from Li+, weakening the binding energy between Li+ and THF, whereas the anions are transported into the solvation shell of Li+, forming an anion-rich solvation structure. In addition to accelerating the Li+ desolvation process, this unique solvation structure optimizes the composition of the CEI film, making it thin, dense, homogeneous, and rich in inorganic components, and thus improving the interfacial stability of the battery. As a result, the assembled LiFePO4/Li half-cell shows excellent electrochemical performances at low temperature. That is, it can maintain a high discharge specific capacity of 124.2 mAh g−1 after 100 cycles at a rate of 0.2C at −20°C.

We have employed the Optimal Homopotic Asymptotic Method technique to solve the equation of the system. The effects and influences of Casson factors, permeability, flow constraints, Prandtl values related to flow and thermal dissipation, and boundary layer profiles have been studied. From the results, it is concluded that thermal parameters and porousness have affected the system, and the upsurge in the porousness actually decreases heat transport effects and proportions. The results of this study are relevant to the development of more effective porous electrodes for achieving high performance with long cycle life.
