The extraction and identification of voltage inconsistency characteristics serve as vital methods for conducting safety risk assessments and early warnings of batteries. However, the inconsistency features caused by variations in cell's basic properties and various abusive behaviors remain unclear. To address this, a series of battery module cycling tests were conducted to comprehensively analyze inconsistency features and quantify these features using mean normalization (MN) and coefficient of consistency variation methods. Some inconsistency features such as “V-type” and “Λ-type” features, sharp fall feature, and continuous increase of deviation feature, that caused by the variation of initial SOC, capacity, and resistance were captured and quantitatively analyzed. Moreover, the inconsistency features of mechanical deformation, overcharge, over-discharge and low-temperature operation were investigated. “V-type” feature and sharp fall of MN value feature can be found in mechanical deformation, overcharge, and low-temperature operation at 0.5C-rate. For the cell with 6.8 mm indentation depth, the ISC induced continuous increase of low voltage deviation with cycling was also characterized. For low-temperature operation at high C-rates, the “V-type” feature vanished but the sharp fall feature aggravated. These results provide insight into understanding voltage inconsistency features and highlight new directions for safety risk assessment.</div></div>","PeriodicalId":15942,"journal":{"name":"Journal of energy storage","volume":"115 ","pages":"Article 116007"},"PeriodicalIF":8.9,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143508791","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}

However, challenges such as high costs, solvent dependency, and limited functionality have hindered their widespread adoption. This study addresses these challenges by repurposing untreated waste cardboard to create oriented aerogels through a solvent-free directional freeze-casting technique. The aerogel's hierarchical porosity facilitates the efficient encapsulation of n-eicosane with 87.48 % loading. This is followed by sealing the composite with polydimethylsiloxane to create a shape-stabilized composite with a latent heat of 188.64 J/g. Unlike previous approaches that rely on chemical cellulose extraction, our method retains raw wastepaper fibers, significantly reducing production costs to $0.106/g. The composite demonstrates exceptional thermal stability, with less than 2.1 % enthalpy loss after 200 thermal cycles, and effectively prevents PCM leakage even when exposed to 60 °C for 80 min. Dynamic indoor and outdoor experiments conducted in Kunming, a region with temperature fluctuations greater than 15 °C, show a reduction in peak temperature by 4.8 °C and an extended thermal retention period 2.3 times longer than without the composite. Additionally, the phase change composite exhibits excellent cushioning properties in its molten state, as validated by controlled impact tests.

The result shows that the Pd-doping has better stability in comparison to the Pt-doped and Ru-doped TiH₄. Furthermore, the calculated hydrogen dissociation energy of TiH₄ is 2.7613 eV. Note that these noble metals can improve the hydrogen decomposed capacity of TiH₄ because the dissociation energy of the TM-doped TiH₄ is lower than that of the parent TiH₄. In particular, the Ru-doping has better hydrogen decomposed capacity compared to the Pd-doping and Pt-doping. Naturally, the better dehydrogenation of the TM-doped TiH₄ is that these additive noble metals weaken the localized hybridization between Ti and H, which is demonstrated by the Ti<img>H bond. In addition, the undoped TiH₄ and the TM-doped TiH₄ show ultraviolet properties. In particular, the Ru-doping induces the main peak to occur migration from the ultraviolet region to the visible light region for TiH₄ hydrogen storage material.

The integration of WS₂ quantum dots and NCP microflowers within the Ti₃C₂ layers (NCP-M-W) significantly enhances the electrocatalytic efficiency of the NCP-M-W composite by eliminating the restacking issue, thereby making it a highly effective electrode for energy storage applications. Subsequently, the advantages of synthesizing the NCP-M-W with ternary metal formulation increase the layer-to-layer distance that allows the KOH electrolyte to penetrate the inner surface of the electrode.

To investigate the heat transfer mechanism of PCMs under different heat source powers and foam metal pore densities, a visualized thermal energy storage device was designed and constructed in this study. The effects of heat source power and the pore density of copper foam metal on the thermal properties of the composite PCMs, including internal temperature differences, equivalent thermal conductivity, comprehensive heat transfer coefficient, and heat storage performance during the melting process, were thoroughly analyzed. An empirical correlation for calculating the Nusselt number (<em>Nu</em>) of the composite PCMs was also derived. The research results indicate that the rate of temperature rise in the internal temperature difference of the composite PCMs increased with the rise in heat source power, while the melting time shortened accordingly. When the heat source power was increased from 30 W to 90 W, for composite PCMs with copper foam, the pore density of copper foam increased from 5PPI to 25PPI, and the rate of temperature rise in the internal temperature difference during the melting process enhanced from 176.9 % to 183.5 %, while the reduction in melting time enhanced from 61.9 % to 62.5 %.
