Complex battery fault mechanisms and limited poor-quality data collection impede fault detection for battery systems under real-world conditions. This paper proposes a novel graph-guided fault detection method designed to recognize concealed anomalies in realistic data. Graphs guided by physical relationships are constructed for learning the dynamic evolution of physical quantities under normal conditions and their potential change characteristics in fault scenarios. An ensemble Graph Sample and Aggregate Network model are developed to tackle sample distribution imbalances and non-uniformity battery system specifications across vehicles. Failure risk probabilities for diverse battery charging and discharging segments are derived. An ablation study verifies the necessity of ensemble learning in addressing imbalanced datasets. Analysis of 102,095 segments across 86 vehicles with different battery material systems, battery capacities, and numbers of cells and temperature sensors confirms the robustness and generalization of the proposed method, yielding a recall of 98.37%. By introducing the graph, spatio-temporal global fault characteristics of battery systems are automatically extracted. The coupling relationship and evolution of physical quantities under both normal and faulty states are established, effectively uncovering fault information hidden in collected battery data without observable anomalies. The safety state of battery systems is reflected in terms of failure risk probability, providing reliable data support for battery system maintenance.</div></div>","PeriodicalId":15728,"journal":{"name":"Journal of Energy Chemistry","volume":"106 ","pages":"Pages 507-522"},"PeriodicalIF":13.1,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143747800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we employed triphenylphosphine (TPP) and triphenylphosphine oxide (TPPO) as the model passivators in p-MPSCs. TPPO has a more negatively charged center than TPP, which enables its stronger coordination with one of the most common and detrimental defects at the GBs—undercoordinated lead. When added into the perovskite with the same ratio, TPPO passivates defects more significantly and thus less TPPO remaining inactive compared with TPP. Inactive organic passivators accumulated at the GBs could impose barriers to charge carrier transportation. Indeed, TPPO improves the device performance more significantly with a champion PCE of 20.54% achieved.

However, the underlying relationship between high-rate cycling and electrode degradation for LRMO, particularly concerning structural evolution, still remains unclear. Benefiting from the high time resolution abilities of liquid-metal-jet operando two-dimensional X-ray diffraction, it is observed that the Li<sub>2</sub>MnO<sub>3</sub> phase in LRMO is gradually activated accompanied by the emergence of oxygen vacancies during cycling at 1 C (1 C = 250 mA/g).

A comprehensive understanding of the low-temperature aging mechanisms throughout the whole life cycle of LIBs is crucial. However, existing research is limited, which typically focuses on capacity degradation to 80%. To fill this gap, this paper conducts low-temperature cyclic aging tests at three different charging rates. The investigation employs differential voltage analysis, the distribution of relaxation times technique, and disassembly characterization to explore both thermodynamic degradation and kinetic degradation, alongside a correlation analysis of the factors influencing these degradation processes. The results reveal two distinct knee points in the capacity decline of LIBs during the whole life cycle, in contrast to prior studies identifying only one. Before the first knee point, the thickening of the SEI film dominates capacity loss, with higher charging rates accelerating the process. After the first knee point, the main degradation mechanisms shift to lithium plating and the fracture of the positive electrode active particles. These two aging factors become more pronounced with ongoing cycling, culminating in a second knee point in capacity decline. Notably, a novel finding demonstrates that after the second knee point, capacity degradation progresses faster at lower charging rates compared to medium rates. The reason is the fracture of graphite particles also becomes a critical contributor to the severe capacity degradation at lower charging rates. These insights will guide the designs of next-generation low-temperature LIBs and low-temperature battery management systems.</div></div>","PeriodicalId":15728,"journal":{"name":"Journal of Energy Chemistry","volume":"106 ","pages":"Pages 31-43"},"PeriodicalIF":13.1,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143680006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their widespread application is hindered by Zn corrosion and uncontrolled Zn dendrite growth. One promising approach involves creating a functional organic-inorganic interface on the Zn surface. Traditional binders, such as polyvinylidene fluoride (PVDF), fail to regulate water activity and ion migration, limiting the effectiveness of the interface. Herein, we introduce an aqueous dual ionic/electronic conducting binder, poly(3,4-ethylenedioxythiophene): polystyrene sulfonate (PEDOT:PSS), to build a water-scarce, Zn<sup>2+</sup>-enriched interface. Our findings demonstrate that PEDOT:PSS not only facilitates uniform distribution of inorganic fillers, forming a cohesive and compact interface, but also significantly enhances mechanical integrity. Additionally, the sulfonate groups within the binder matrix disrupt the hydrogen bond network of water molecules, reducing water activity and lowering the desolvation energy barrier of Zn(H<sub>2</sub>O)<sub>6</sub><sup>2+</sup> clusters. Therefore, the transference number of Zn<sup>2+</sup> is elevated to 0.81 (compared to 0.61 with PVDF), mitigating undesirable side reactions and enabling dendrite-less Zn deposition.
