Exploring the effect of the surface terminal regulation on the performance of MXene is crucial yet challenging. In this study, the phosphorus-terminal groups (P─C and P─O) with a P concentration of 2.71 at% are successfully tailored and interlayer spacing is enhanced during the ultraviolet light irradiation process of Ti3C2Tx MXene, which is the first report of photoinduced P-doped MXene modification. Density functional theory calculations show that P doping is more likely to be adsorbed by ─O groups than to replace Ti vacancy, and the stability of the MXene electrode can be improved by the introduction of a phosphorus terminal. The resulting P-doped Ti3C2Tx MXene shows a significant increased pseudocapacitance performance, achieving superior results compared with traditional resistance furnace heating methods. The specific capacitance achieves 500.5 F g−1, due to the ─P functional group and Ti atom double reoxidation sites. Furthermore, a Zn-HSC device of P-doped Ti3C2Tx exhibits a specific capacitance of 207.4 F g−1 and energy densities of 56.5 Wh kg−1. This study also provides valuable insights and a reference for the realization of phosphorus doping in other MXene materials.","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"4 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.20240117","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145012753","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}

Reported work has focused mainly on the electrochemical properties of complete electrolyte without any insight of the necessity of complete electrolyte and contribution of thermal processes and individual electrolyte components towards the electrical output. Therefore, in present research, the electrochemical properties of complete electrolyte and its individual chemical components (Amido black 10 B, Iso-amyl alcohol, H3PO4, KOH) have been investigated. It is observed that each chemical individually has some inherent electrical properties (zero or non-zero potential/current) due to thermal processes. Photo-illuminated complete electrolyte shows 13,750 μA current and 855 mV potential as a result of photogalvanics. In illuminated conditions, the role of thermal process in current/potential generation of about maximum possible 3715 μA/347 mV cannot be denied. Therefore, the rest current/potential generation, i.e., ~10,000 μA/500 mV may be attributed to photo-induced processes in the complete electrolyte. Thus, on the basis of these observations, it may be concluded that the reductant or sensitizer or alkali or surfactant individually shows only thermal-induced potential and current. But, the complete electrolyte is able to show photogalvanics (i.e., conversion of solar energy into electrical energy) in the presence of the sunlight. In photogalvanics, the obtained current and potential may be attributed to combined effect of thermal and photo-processes. Hence, it may be concluded that use of complete electrolyte in photo-galvanic cells is a necessary condition for harvesting solar energy commercially through photogalvanics. Photogalvanic cells based on complete electrolyte only may be of industrial relevance.","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"4 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.20240087","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145013223","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}

But the side reactions of self-corrosion and passive film severely impede the advancement of aluminum batteries. Besides, the ideal matched electrolyte system and cathode working mechanism still need to be explored. Herein, a high specific energy aqueous aluminum–manganese battery is constructed by interfacial modified aluminum anode, high concentration electrolyte and layered manganese dioxide cathode. At the anode, in addition to boosting the wettability of the interface between the electrolyte and aluminum electrode, the altered surface of aluminum anode can also retard side reactions. At the same time, high concentration electrolyte (5 mol L−1 Al(OTF)3) with a broad electrochemical window allows the battery system to attain a specific capacity of 452 mAh g−1 at 50 mA g−1 and an energy density of 542 Wh kg−1, with greatly increased cycle stability. At the cathode, the mechanism investigation reveals that δ-MnO2 is reduced to soluble Mn2+ during the first cycle discharge, whereas AlxMn(1−x)O2 generates during the charging process, acting as a highly reversible active material in the succeeding cycle. This comprehensive study paves the way for the development of aluminum-based energy storage devices.","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"4 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.20240093","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145013105","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, the issue of dendrite growth has emerged as a significant obstacle in battery development. Excessive dendrite growth during charging and discharging processes can lead to battery short-circuiting, degradation of electrochemical performance, reduced cycle life, and abnormal exothermic events. Consequently, understanding the dendrite growth process has become a key challenge for researchers. In this study, we investigated dendrite growth mechanisms in batteries using a combined machine learning approach, specifically a two-dimensional artificial convolutional neural network (CNN) model, along with computational methods. We developed two distinct computer models to predict dendrite growth in batteries. The CNN-1 model employs standard CNN techniques for dendritic growth prediction, while CNN-2 integrates additional physical parameters to enhance model robustness. Our results demonstrate that CNN-2 significantly enhances prediction accuracy, offering deeper insights into the impact of physical factors on dendritic growth. This improved model effectively captures the dynamic nature of dendrite formation, exhibiting high accuracy and sensitivity. These findings contribute to the advancement of safer and more reliable energy storage systems.","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"4 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.20240088","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145013291","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}

The conductive and porous CF film not only ensures the uniform distribution of Ni-Co-S nanosheets but also offers an efficient pathway for the transportation of electrons and electrolyte ions. The Ni-Co-S nanosheet arrays, characterized by their small thickness and open pores, facilitate to provide a rapid diffusion path for electrolyte ions and expose sufficient active surfaces for charge storage.

NiCu, a transition metal alloy, has shown great potential as an efficient and cost-effective catalyst for AOR.

In this study, the aging behavior and thermal safety of LIBs at different overdischarge cut-off voltages are investigated. The results show that overdischarge significantly affects the discharge ability of the battery, with a capacity decay rate of 38.2% at an overdischarge cut-off voltage is 0.5 V. Electrochemical test results indicate that overdischarge accelerates the loss of the active materials and the increase of impedance. Quantitative analysis shows that the conductive loss and lithium inventory loss are the main causes of battery aging. The disassembly images and further physicochemical characterization indicate that with the decrease of overdischarge voltage, the dissolution of copper current collector and the increase of electrode surface attachments intensify. The differential scanning calorimetry test indicates that the thermal stability of the anode is reduced. These aging behaviors lead to the loss of active materials, the damage of the electrode structure, and the increase of gas production inside the overdischarge batteries, which results in the advance of the thermal runaway time, the decrease of the thermal runaway onset temperature and the thermal runaway peak temperature.","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"4 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.70008","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144582168","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}
