Solid polymer electrolytes (SPEs) for lithium metal batteries have garnered considerable interests owing to their low cost, flexibility, lightweight, and favorable interfacial compatibility with battery electrodes. Their soft mechanical nature compared solid inorganic give them a large advantage be used in pressure solid-state batteries, which can avoid the cost weight of cages. However, application SPEs is hindered by relatively ionic conductivity. In addressing this limitation, enormous efforts are devoted experimental investigation theoretical calculations/simulation new classes. Recently, metal-organic frameworks (MOFs) been shown effective enhancing ion transport SPEs. mechanisms Li

High-energy density dielectrics for electrostatic capacitors are in urgent demand advanced electronics and electrical power systems. Poly(vinylidene fluoride) (PVDF) based nanocomposites have attracted remarkable attention by intrinsic high polarization, flexibility, low density, outstanding processability. However, it is still challenging to achieve significant improvement energy due the common contradictions between electric polarization breakdown strength. Here, we proposed a novel facile strategy that simultaneously achieves construction of in-plane oriented BaTiO3 nanowires crystallization modulation PVDF matrix via an in-situ uniaxial stretch process. The polar phase transition enhanced Young's modulus facilitate synergetic voltage endurance capability matrix. Additionally, aligned distribution could reduce contact probability nanowire tips, thus alleviating field concentration hindering conductive path. Finally, record 38.3 J/cm3 40.9 achieved single layer optimized sandwich-structured nanocomposite, respectively. This work provides unique structural design universal method dielectric with ultrahigh which presents promising prospect practical application modern storage

Опубликована: Март 19, 2025

Abstract Alkali metal batteries (AMBs) have undergone substantial development in portable devices due to their high energy density and durable cycle performance. However, with the rising demand for smart wearable electronic devices, a growing focus on safety durability becomes increasingly apparent. An effective strategy address these increased requirements involves employing quasi-solid gel electrolytes (QSGEs). This review focuses application of QSGEs AMBs, emphasizing four types influence battery performance stability. First, self-healing gels are discussed prolong life enhance through self-repair mechanisms. Then, flexible explored mechanical flexibility, making them suitable electronics. In addition, biomimetic inspired by natural designs introduced high-performance AMBs. Furthermore, biomass materials presented, derived from biomaterials, offering environmental friendliness biocompatibility. Finally, perspectives challenges future developments terms enhancing ionic conductivity, strength, stability novel materials. The underscores significant contributions AMBs performance, including lifespan, safety, adaptability, providing new insights directions research applications field.

Silicon is considered one of the most promising anode materials owing to its high theoretical energy density, however, volume expansion/contraction during electrochemical lithiation/delithiation cycles leads instability solid electrolyte interphase (SEI), which ultimately results in capacity degradation. Herein, local stress and deformation evolution status an SEI layer on particle are investigated through a quantitative electrochemical-mechanical model. The impacts structural uniformity, mechanical strength, operating conditions stability detail. simulation demonstrate that when silicon radius decreases from 800 nm 600 400 nm, failure time increases 129% 165%, respectively, original time; When defect depth ratio reduced 0.6 0.4 0.2, 174% 237%, respectively; For discharge rate, extended 134% 239% at 0.2 C 0.3 C, compared with 0.1 C. This work provides insight into rational design stable layers sheds light possible methods for constructing silicon-based lithium-ion batteries longer cycling lives.
