Abstract To achieve high ionic conductivity for solid electrolyte, an artificial Li‐rich interface layer of about 60 nm thick has been constructed in polymer‐based poly(ethylene oxide)‐lithium bis(trifluoromethanesulfonyl)imide composite electrolyte (briefly noted as PEO m ) by adding Li‐based alloys. As revealed high‐resolution transmission electron microscopy and energy loss spectroscopy, amorphous feature is created around the alloy particles with gradient distribution Li across it....
The development process of electrified vehicles can benefit significantly from computer-aided engineering tools that predict the multi-physics response batteries during abusive events. A coupled structural, electrical, electrochemical, and thermal model framework has been developed within commercially available LS-DYNA software. finite element leverages a three-dimensional mesh structure fully resolves unit cell components. mechanical solver predicts distributed stress strain with failure...
SnS with high theoretical capacity is a promising anode material for lithium‐ion batteries. However, dramatic volume changes of during repeated discharge/charge cycles result in fractures or even pulverization electrode, leading to rapid degradation. To solve this problem, we construct dual‐carbon‐confined nanostructure (denoted as SnS@C/rGO) by depositing semi‐graphitized carbon layers on reduced graphene oxide (rGO) supported nanoplates high‐temperature reduction. The dual rGO and situ...
To develop anode materials with superior volumetric storage is crucial for practical application of lithium/sodium‐ion batteries. Here, we have developed a micro/nanostructured SnS/few‐layer graphene (SnS/FLG) composite by facile scalable plasma milling. Inside the hybrid, SnS nanoparticles are tightly supported FLG, forming nanosized primary particles as building blocks and assembling to microsized secondary granules. With this unique micro/nanostructure, SnS/FLG possesses high tap density...
SnO 2 , with its high theoretical capacity, abundant resources, and environmental friendliness, is widely regarded as a potential anode material for lithium‐ion batteries (LIBs). Nevertheless, the coarsening of Sn nanoparticles impedes reconversion back to resulting in low coulombic efficiency rapid capacity decay. In this study, we fabricated heterostructure by combining MoS nanosheets via plasma‐assisted milling. The consists in‐situ exfoliated predominantly 1 T phase, which tightly encase...
The potential risk of transition metal (TM) ion dissolution is a prevalent issue in nearly all layered oxide cathodes. While the detrimental effects this are widely discussed context cathode material design, implications for electrolyte design receive comparatively less attention. In fact, severe decomposition frequently occurs after TM ions. This phenomenon typically attributed to catalytic However, there lack research that clearly explains destabilization electrolyte. study delves into...
Abstract Quasi‐solid‐state Zn‐air pouch cells (QZPCs) promise a high energy‐to‐cost ratio while ensuring inherent safety. However, addressing the challenges associated with exploring superior energy‐wise cathode catalysts along their activity origin, and super‐ionic electrolytes remains fundamental task. Herein, realistic high‐performance QZPCs are contrived, underpinned by robust NiVFeCo medium‐entropy metal sulfides (MESs) bifunctional air record‐low potential polarization of 0.523 V,...
Abstract Lithium iron phosphate (LFP) cathode is renowned for high thermal stability and safety, making them a popular choice lithium‐ion batteries. Nevertheless, on one hand, the fast charge/discharge capability fundamentally constrained by low electrical conductivity anisotropic nature of sluggish lithium ion (Li + ) diffusion. On other interface internal structural degradation occurs when subjected to high‐rate condition. Herein, multifunctional boron‐doping graphene/lithium carbonate...
The wide application of Manganese-rich cathode materials have been severely restricted by the large initial irreversible capacity loss, poor cycling stability and low discharge capability at high rate.
