Published: March 15, 2023

SiOx anode has a more durable cycle life than Si, being considered competitive to replace the conventional graphite. usually serves as composites with carbon achieve extended life. However, microstructure dependent Li-ion storage behaviors in /C have received insufficient attention. Herein, this work demonstrates that disorder of can determine ratio inter- and intragranular diffusions. The resulted variation platform characteristics will result different compatibility when matching . Rational induced intergranular diffusion benefit phase transition /C, benefiting electrochemical performance. Through series quantitative calculations situ X-ray diffraction characterizations, proposes rational strategy for future optimization, thus achieving preferable performance anode.

The use of Battery Electric Vehicles is one the biggest transformations in field sustainable development, holding potential to address many sustainability challenges. Despite their high energy efficiency, utilisation these vehicles remains largely underexplored due several factors. One prominent factors phenomenon range anxiety (RA). This review aims provide an overview phenomenon, identifying its primary influencing variables and strategies for mitigating it. places particular emphasis on methodologies tools employed assessing related Following PRISMA guidelines, a systematic search was performed PubMed, Scopus, APA PsycInfo, using following keywords: "range" AND ("stress" OR "anxiety") ALL ("electric" "vehicle"). protocol registered with OSF, registration number https://doi.org/10.17605/OSF.IO/FN4VW. articles were selected by two independent authors. methodological quality risk bias assessed.

MXenes and Their Derivatives for Advanced Solid‐State Energy Storage Devices

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 33(41)

Published: June 7, 2023

Abstract Solid‐state energy storage devices (SSESDs) are believed to significantly improve safety, long‐term electrochemical/thermal stability, and energy/power density as well reduce packaging demands, showing the huge application potential in large‐scale storage. Nevertheless, some key issues like low ionic conductivities, poor interface contact, dendrites growth limit practical of SSESDs. In recent years, MXenes for SSESDs have received reassuring advances on account unique parameters. overall reviews about subject seldom. this review, current their derivatives solid‐state Li–metal, Li‐ion, Li–I/S, Na‐ion, Zn–air, Zn–metal batteries, supercapacitors cathode/anode optimization, medication, electrolyte fillers, etc., comprehensively reviewed. First all, essential principles shown, such precursors, etching/delamination strategies, superior properties systems. Meanwhile, classification evaluation parameters electrolytes summarized. Subsequently, application, modification mechanism, design strategy boosting electrochemical behaviors systematically reviewed discussed. At last, perspectives challenges future construction strategies recommended. This review shall assist scientists build advanced with along safety.

Is Soft Carbon a More Suitable Match for SiO_x in Li‐Ion Battery Anodes?

Small, Journal Year: 2023, Volume and Issue: 19(37)

Published: May 5, 2023

Silicon oxide (SiOx ), inheriting the high-capacity characteristic of silicon-based materials but possessing superior cycling stability, is a promising anode material for next-generation Li-ion batteries. SiOx typically applied in combination with graphite (Gr), limited durability /Gr composites curtails large-scale applications. In this work, demonstrated part related to presence bidirectional diffusion at interface, which driven by their intrinsic working potential differences and concentration gradients. When Li on Li-rich surface captured Gr, shrinks, hindering further lithiation. The use soft carbon (SC) instead Gr can prevent such instability demonstrated. higher SC avoids compression thus allowing scenario, evolution gradient conforms its spontaneous lithiation process, benefiting electrochemical performance. These results highlight focus as strategy rational optimization /C toward improved battery
