The sodium (Na) has abundant resources in the earth's crust and its physicochemical properties are similar to Li, which ensure that sodium-ion batteries (SIBs) are considered as a substitute for LIBs in certain fields. Unfortunately, the lower energy density of SIBs limits its application range. Therefore, studying high specific capacity anode materials to improve the energy density of batteries is an important direction of SIBs. Red-phosphorus (P)-based anode materials are ideal candidates for high energy density SIBs because of their high theoretical specific capacity and suitable working voltage. However, the red-P-based anode materials for SIBs meet intractable challenges in terms of the poor electrical conductivity and huge volume changes during cycling, resulting in inferior electrochemical performances. In this article, the research progress of red-P-based anode material for SIBs in recent years, including the red-P/carbon composite, element-doped composite, metal phosphide, and stable interface design, is reviewed. Herein, the decisive role is highlighted that composite design with highly conductive carbon materials plays in addressing the challenges associated with red-P-based anodes and a perspective on their development direction is given.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143119410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The inferior mechanical performance and inadequate ionic conductivity of polymer electrolytes have hampered their widespread use. By utilizing a matrix of polyethylene oxide (PEO) along with succinonitrile (SN) and lithium bis(trifluoromethane)sulfonimide (LiTFSI) as additives, the WPI enhances the stability of the PSL electrolyte structure through reinforced internal hydrogen bonds of poly(amic acid), its precursor, post-thermal imidization in the presence of deionized water. This structural enhancement leads to improved mechanical properties, evidenced by a tensile strength of 12.2 MPa at a high porosity of 85.6%. The WPI-PSL electrolyte exhibits favorable ionic conductivity, thermal stability, and electrochemical compatibility with lithium metal. As a result, the WPI-PSL configuration demonstrates exceptional performance in a LiFePO4/Li ASSLIBs system, showcasing outstanding cycling performance at both 30 and 60 °C, with capacity retention ratios reaching 94.6% and 96% after 100 cycles at 0.3 C, respectively.

However, there is currently a lack of reported methods for large-scale preparation and high-efficiency molding of these flexible electrodes. In this study, PBAT-co-PEG/NaSCN blends-based ionic conductive thermoplastic elastomer (ICTE) are successfully prepared by initially conducting melt transesterification, followed by melt blending. The STENG, featuring an ICTE electrode, exhibited a remarkable open-circuit voltage of 50 V, short-circuit current of 460 nA and charge transfer of 16 nC. With the aid of Fourier transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC), the conduction mechanism of ICTE is elucidated. Due to good fluidity and processing performance, bars of ICTE suitable for mechanical properties test could be conveniently prepared via injection molding, which demonstrates the tensile strength and elongation, 13 MPa and 2500%, respectively. A 4 × 4 cm2 STENG fabricated with ICTE electrode could not only have good energy-harvesting performance but also could be used in a sensor to sense the motion detection.

Specifically, the electrolyte filling process is critical for optimal cell performance. In this study, the unknown effects of differential pressure, different temperature for the materials, and the geometrical cell design are investigated through the aspect ratio (lengths to height ratio) on the wetting behavior of LIB cells. Using a custom-designed test stand, impedance change |ż| at 1 Hz is measured during electrolyte dispensing and wetting while varying temperature, pressure, and the cells’ aspect ratio. In the results, it is indicated that lower evacuation pressures significantly increase the wetting rate, reducing wetting durations. Higher differential pressures enhance wetting efficiency by compressing the electrode-separator composite (ESC) materials. Elevated electrolyte temperatures decrease viscosity, resulting in faster wetting times. Temperature variations between the ESC material and electrolyte lead to heat equalization, with no discernible impact on partial gas pressure. Additionally, increased aspect ratios in cell design reduce wetting times due to shorter distances for the wetting front to travel. In these findings, valuable insights are provided for optimizing battery cell manufacturing, contributing to improved efficiency and performance in next-generation battery technologies.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ente.202401338","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143119087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To tackle this issue effectively, it is imperative to pierce beyond the superficial causes of lithium-ion battery (LIB) failures—such as equipment malfunctions or physical damage—and to excavate the underlying triggers. This nuanced approach is pivotal to refining EV quality, diminishing fire incidents, and bolstering consumer trust. While issues that are readily apparent to consumers, like spontaneous battery degradation, vehicular collisions, or submersion, may seem like the primary culprits, they merely scratch the surface of a more complex problem. The true mechanisms behind these fires involve internal and external short circuits, yet these explanations fall short in providing actionable guidance for manufacturers or end-users to enhance LIB safety. The heart of the issue is identifying the root causes that bridge failure triggers and resulting fires. A total of 20 root causes are identified, linking them to real-world scenarios like overcharging causing internal shorts or wire harness issues leading to external shorts. With this insight, stakeholders can more effectively investigate and understand EV LIB fire incidents, bolstering EV safety and reliability, and promoting consumer confidence.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"12 12","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142862269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
