Abstract Layered transition metal dichalcogenides (LTMDs), such as MoS 2 , are promising anode materials for high‐energy‐density lithium‐ion batteries (LIBs) due to their high specific capacities. However, practical applications hindered by poor cycling stability resulting from the instable structure during charge/discharge and inherently low electronic conductivity.

ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: 16(5), P. 5915 - 5925

Published: Jan. 26, 2024

The development of a high-rate SiO lithium-ion battery anode is seriously limited by its low intrinsic conductivity, sluggish interfacial charge transfer (ICT), and unstable dynamic interface. To tackle the above issues, encapsulation engineering for effectively regulating reaction thus realizing stable solid electrolyte interphase significantly important. Hybrid coating, which aims to enhance coupled e-/Li+ transport via employment dual layers, has emerged as promising strategy. Herein, we construct hybrid MXene-graphene oxide (GO) coating layer on microparticles. In design, Ti3C2Tx MXene acts "bridge", forms close covalent connection with GO through Ti-O-Si Ti-O-C bonds, respectively, greatly reducing ICT resistance. Moreover, rich surface groups (e.g., -OH, -F) outer layers an intertwined porous framework synergistically enable pseudocapacitance dominated behavior, beneficial fast storage. Accordingly, as-made Si@MXene@GO exhibits considerably reinforced storage performance in terms superior rate (1175.9 mA h g-1 at 5 A g-1) long cycling stability (1087.6 capacity retained after 1000 cycles 2.0 g-1). In-depth chemical composition analysis further reveals that inorganically gradient distribution LiF Li2O formed electrolyte/anode interface ensures mechanical during repeated cycles. This work paves feasible way maximizing potential anodes toward fast-charging batteries.

This work demonstrates impact on electrochemical performance silicon/carbon composites from two perspectives: 1) affects loadings particles; 2) structural stability and mechanical properties. The smaller substrate cannot support high loadings, which results forming thick shell surface, thereby being detrimental cycling diffusion electrons ions. On top that, larger has poor due fragility, also not conducive realizing long cycle life rate performance. Achieving excellent performances should match proper content. study will provide important insights into rational design based substrates.
